Wiring and protectionFeeders.

002 Minimum rating and size.
(1) For other than one- or two-family dwelling feeders rated up to 400 amperes, if the feeder conductors have a lesser ampacity than the equipment rating that they terminate in or on, an identification plate showing conductor ampacity stating: "Feeder conductor ampacity: _____ " must be installed on the equipment at the load end of the feeder conductors.
005 Diagrams of feeders.
(2) Other than plan review projects, the installer must provide a one-line diagram showing the service and feeder details for the project before the initial inspection can be approved for all nondwelling services or feeders:
(a) Larger than 400 amperes; or
(b) Over 600 volts.
The diagram must be signed and dated by the project owner if the owner is doing the work, the assigned administrator or master electrician if an electrical contractor is doing the work, or stamped with an engineer's mark and signature who is registered under chapter 18.43 RCW. The diagram must show:
(c) All services including: Wire size(s), wire type(s), service size(s) (e.g., voltage, phase, ampacity), overcurrent protection, available symmetrical fault current at the service point, equipment short-circuit rating, total load before and after demand factors have been applied including any demand factors used, and a panel schedule where multiple disconnecting devices are present; and
(d) All feeders including: Wire size(s), wire type(s), feeder size(s) (e.g., voltage, phase, ampacity), overcurrent protection, total calculated load before and after demand factors have been applied including any demand factors used, and a panel schedule(s) where multiple disconnecting devices are present.
If the installer deviates, in any way, from the service/feeder design shown on the diagram, a supplemental diagram must be supplied to the inspector showing the most recent design before inspection can proceed. Load reductions and moving branch circuit locations within a panelboard do not require a supplemental diagram. Written documentation must also be provided to the inspector that the supplemental diagram was provided to the project owner at the time of submission to the inspector.
The diagram must be available on the job site during the inspection process.
010 Ground fault protection testing.
(3) Equipment ground fault protection systems required by the NEC must be tested prior to being placed into service to verify proper installation and operation of the system as determined by the manufacturer's published instructions. This test or a subsequent test must include all system feeders unless the installer can demonstrate, in a manner acceptable to the inspector, that there are no grounded conductor connections to the feeder(s). A firm having qualified personnel and proper equipment must perform the tests required. A copy of the manufacturer's performance testing instructions and a written performance acceptance test record signed by the person performing the test must be available at the time of inspection. The performance acceptance test record must include test details including, but not limited to, all trip settings and measurements taken during the test.

(1) The owner, the owner's agent, or the electrical contractor making the installation must consult the serving utility regarding the utility's service entrance requirements for equipment location and meter equipment requirements before installing the service and equipment. Provisions for a meter and related equipment, an attachment of a service drop, or an underground service lateral must be made at a location acceptable to the serving utility. The point of contact for a service drop must permit the clearances required by the NEC.
(2) A firewall must have a minimum two-hour rating as defined by the local building official to be considered a building separation in accordance with Article 100 NEC.
(3) The height of the center of the service meter must be as required by the serving utility. Secondary instrument transformer metering conductor(s) are not permitted in the service raceway.
028 Service or other masts.
(4) Conduit extended through the roof to provide means of attaching:
(a) All overhead drops for service, feeder, or branch circuits exceeding #1 AWG aluminum or #3 AWG copper must be rigid steel galvanized conduit no smaller than 2 inches.
(b) All overhead drops for service, feeder or branch circuits not exceeding #1 AWG aluminum or #3 AWG copper must be rigid steel galvanized conduit no smaller than 1 1/4 inches. The installation must comply with drawings E-101 and/or E-102, or must provide equivalent strength by other approved means. Masts for altered or relocated installations will be permitted to comply with drawing E-103.
Notes to drawings E-101, E-102, and E-103
(1)An approved roof flashing must be installed on each mast where it passes through a roof. Plastic, nonhardening mastic must be placed between lead-type flashings and the conduit. Neoprene type flashings will also be permitted to be used.
(2)Masts must be braced, secured, and supported in such a manner that no pressure from the attached conductors will be exerted on a roof flashing, meter base, or other enclosures.
(3)Utilization of couplings for a mast is permitted only below the point the mast is braced, secured, or supported. There must be a minimum of two means of support above any couplings used. A properly installed cable or stiff leg type support qualifies as one of the two required means of support.
(4)Except as otherwise required by the serving utility, service mast support guys must be installed if the service drop attaches to the mast more than 24 inches above the roof line or if the service drop is greater than 100 feet in length from the pole or support. Masts for support of other than service drops must comply with this requirement as well.
(5)Intermediate support masts must be installed in an approved manner with methods identical or equal to those required for service masts.
(6)For altered services, where it is impractical to install U bolt mast supports due to interior walls remaining closed, it will be permissible to use other alternate mast support methods such as heavy gauge, galvanized, electrical channel material that is secured to two or more wooden studs with 5/16 inch diameter or larger galvanized lag bolts.
(7)Conductors must extend at least 18 inches from all mastheads to permit connection to the connecting overhead wiring.
040 Service conductors - Two-family and multiple-occupancy buildings.
(5) Two-family and multiple-occupancy buildings. A second or additional service drop or lateral to a building having more than one occupancy will be permitted to be installed at a location separate from other service drops or laterals to the building provided that all the following conditions are complied with:
(a) Each service drop or lateral must be sized in accordance with the NEC for the calculated load to be served by the conductors;
(b) Each service drop or lateral must terminate in listed metering/service equipment;
(c) Each occupant must have access to the occupant's service disconnecting means;
(d) No more than six service disconnects may be supplied from a single transformer;
(e) All service drops or laterals supplying a building must originate at the same transformer or power supply;
(f) A permanent identification plate must be placed at each service disconnect location that identifies all other service disconnect locations in or on the building, the area or units served by each, the total number of service disconnecting means on the building/structure and the area or units served. If a structure consists of multiple buildings (i.e., by virtue of fire separation), all service disconnects in or on the entire structure must be labeled to identify all service disconnects in or on the structure; and
(g) A permanent identification plate must be placed at each feeder disconnecting means identifying the area or units served if the feeder disconnecting means is remote from the area or unit served.
042 Service conductor - Size and rating.
(6) For other than one- or two-family dwelling services rated up to 400 amperes, if the service conductors have a lesser ampacity than the overcurrent protection, permitted by NEC 230.90 or NEC 310.15, or the equipment rating that they terminate in or on, an identification plate showing the ampacity of the conductors stating: "Service conductor ampacity: _____" must be installed on the service equipment.
043 Wiring methods for 1000 volts, nominal or less.
(7) The installation of service conductors not exceeding 1000 volts, nominal, within a building or structure is limited to the following methods: Galvanized or aluminum rigid metal conduit; galvanized intermediate metal conduit; wireways; busways; auxiliary gutters; minimum schedule 40 rigid polyvinyl chloride conduit; cablebus; or mineral-insulated, metal-sheathed cable (type MI).
(8) Electrical metallic tubing must not be installed as the wiring method for service entrance conductors inside a building. Existing electrical metallic tubing, installed prior to October 1984, which is properly grounded and used for service entrance conductors may be permitted to remain if the conduit is installed in a nonaccessible location and is the proper size for the installed conductors.
(9) In addition to methods allowed in the NEC, the grounded service conductor is permitted to be identified with a yellow jacket or with one or more yellow stripes.
070 Service equipment - Disconnecting means.
(10) The service disconnecting means must be installed at a readily accessible location in accordance with (a) or (b) of this subsection.
(a) Outside location: Service disconnecting means will be permitted on the building or structure or within sight and within fifteen feet of the building or structure served. The building disconnecting means may supply only one building/structure. The service disconnecting means must have an identification plate with one-half-inch high letters identifying:
(i) The building/structure served; and
(ii) Its function as the building/structure main service disconnect(s).
(b) Inside location: When the service disconnecting means is installed inside the building or structure, it must be located so that the service raceway extends no more than fifteen feet inside the building/structure.
095 Ground-fault protection of equipment.
(11) Equipment ground-fault protection systems required by the NEC must be tested prior to being placed into service to verify proper installation and operation of the system as determined by the manufacturer's published instructions. This test or a subsequent test must include all service voltage feeders unless the installer can demonstrate, in a manner acceptable to the department, that there are no grounded conductor connections to the feeder(s). A firm having qualified personnel and proper equipment must perform the tests required. A copy of the manufacturer's performance testing instructions and a written performance acceptance test record signed by the person performing the test must be available for the inspector at the time of inspection. The performance acceptance test record must include test details including, but not limited to, all trip settings and measurements taken during the test.
200 Wiring methods exceeding 1000 volts.
(12) The installation of service conductors exceeding 1000 volts, nominal, within a building or structure must be limited to the following methods: Galvanized rigid metal conduit, galvanized intermediate metal conduit, schedule 80 polyvinyl chloride conduit, metal-clad cable that is exposed for its entire length, cablebus, or busways.

Wiring and protectionGrounding and bonding.

028 (D)(3) Separately derived system with more than one enclosure.
(1) NEC 250.28 (D)(3) is amended to read: Where a separately derived system supplies more than a single enclosure, the system bonding jumper for each enclosure shall be sized in accordance with 250.28 (D)(1) based on the largest ungrounded feeder/tap conductor serving that enclosure, or a single system bonding jumper shall be installed at the source and sized in accordance with 250.28 (D)(1) based on the equivalent size of the largest supply conductor determined by the largest sum of the areas of the corresponding conductors of each set.
052 Grounding electrodes.
(2) Except for mobile/manufactured homes, a concrete encased grounding electrode must be installed and used at each new building or structure that is built upon a permanent concrete foundation. The electrode must comply, with NEC 250.52 (A)(3). Inspection of the electrode may be accomplished by the following methods:
(a) At the time of inspection of other work on the project, providing the concrete encased electrode is accessible for a visual inspection;
(b) At the time of the service inspection providing the installer has provided a method so the inspector can verify the continuity of the electrode conductor along its entire length, with a minimum 20 foot linear span between testing points (e.g., attaching a length of copper wire to one end of the electrode that reaches the location of the grounding electrode conductor that will enable the inspector to measure the resistance with a standard resistance tester). The concrete encased electrode does not have to be accessible for a visual inspection; or
(c) Other method when prior approval, on a job site basis, is given by the inspector.
If a special inspection trip is required to inspect a grounding electrode conductor, a trip fee will be charged for that inspection in addition to the normal permit fee.
Exception:
If the concrete encased grounding electrode is not available for connection, a ground ring must be installed per NEC 250 or other grounding electrode installed per NEC 250 verified to measure 25 ohms or less to ground. Resistance verification testing must be performed by an independent firm having qualified personnel and proper equipment. A copy of the testing procedures used and a written resistance test record signed by the person performing the test must be available at the time of inspection. The resistance test record must include test details including, but not limited to, the type of test equipment used, the last calibration date of the test equipment, and all measurements taken during the test.
053 (A)(2) Resistance of rod, pipe, and plate electrodes.
(3) For rod, pipe, and plate electrodes other than those installed in accordance with the exception in subsection (2) of this section, if a ground resistance test is not performed to ensure a resistance to ground of 25 ohms or less, two or more electrodes as specified in NEC 250.52 must be installed a minimum of 6 feet apart. A temporary construction service is not required to have more than one made electrode.
(4) For services only, when multiple buildings or structures are located adjacent, but structurally separate from each other, any installed rod, pipe, or plate electrodes used for those services must be installed so that each building's or structure's electrodes are not less than 6 feet apart from the adjacent building's or structure's electrodes.
064 Grounding electrode conductor installation – Physical protection.
(5) Grounding electrode conductors will be considered to be not exposed to physical damage when the conductor(s) are:
(a) Buried more than 12 inches deep in the earth outside the building's footprint;
(b) Encased or covered by 2 inches of concrete or asphalt;
(c) Located inside the building footprint and protected by the building's structural elements or when inside and determined, by the inspector, to not be subject to physical damage; or
(d) Enclosed by a metal or nonmetallic raceway or enclosure. The raceway or enclosure must be approved to protect from severe physical damage if it is not protected by appropriate physical barriers from contact with vehicles, lawn mowers, and other equipment that might damage the conductor or enclosure.
068 Accessibility.
(6) The termination point of a grounding electrode conductor tap to the grounding electrode conductor must be accessible unless the connection is made using an exothermic or irreversible compression connection.
090 Bonding.
(7) Metallic stubs or valves used in nonmetallic plumbing systems are not required to be bonded to the electrical system unless required by an electrical equipment manufacturer's instructions.
(8) Hot and cold water plumbing lines are not required to be bonded together if, at the time of inspection, the inspector can determine the lines are mechanically and electrically joined by one or more metallic mixing valves.
104(B) Bonding - Other metal piping.
(9) For flexible metal gas piping, installed new or extended from an existing rigid metal piping system, either:
(a) Provide a copy of the manufacturer's bonding instructions to the inspector at the time of inspection and follow those instructions; or
(b) The bonding conductor for the gas system must:
(i) Be a minimum 6 AWG copper; and
(ii) Terminate at:
(A) An accessible location at the gas meter end of the gas piping system on either a solid iron gas pipe or a cast flexible gas piping fitting using a listed grounding connector; and
(B) Either the service equipment enclosure, service grounding electrode conductor or electrode, or neutral conductor bus in the service enclosure.
184 Solidly grounded neutral systems over 1000 volts.
(10) In addition to the requirements of NEC 250.184(A), the following applies for:
(a) Existing installations.
(i) The use of a concentric shield will be allowed for use as a neutral conductor for extension, replacement, or repair, if all of the following are complied with:
(A) The existing system uses the concentric shield as a neutral conductor;
(B) Each individual conductor contains a separate concentric shield sized to no less than thirty-three and one-half percent of the ampacity of the phase conductor for three-phase systems or one hundred percent of the ampacity of the phase conductor for single-phase systems;
(C) The new or replacement cable's concentric shield is enclosed inside an outer insulating jacket; and
(D) Existing cable (i.e., existing cable installed directly in the circuit between the work and the circuit's overcurrent device) successfully passes the following tests:
• A cable maintenance high potential dielectric test. The test must be performed in accordance with the cable manufacturer's instruction or the 2019 ANSI/NETA maintenance test specifications; and
• A resistance test of the cable shield. Resistance must be based on the type, size, and length of the conductor used as the cable shield using the conductor properties described in NEC Table 8 Conductor Properties.
An electrical engineer must provide a specific certification to the electrical plan review supervisor in writing that the test results of the maintenance high potential dielectric test and the resistance test have been reviewed by the electrical engineer and that the cable shield is appropriate for the installation. The electrical engineer must stamp the certification document with the engineer's stamp and signature. The document may be in the form of a letter or electrical plans.
Testing results are valid for a period of seven years from the date of testing. Cable will not be required to be tested at a shorter interval.
(ii) A concentric shield used as a neutral conductor in a multigrounded system fulfills the requirements of an equipment grounding conductor.
(b) New installations.
(i) New installations do not include extensions of existing circuits.
(ii) The use of the concentric shield will not be allowed for use as a neutral conductor for new installations. A listed separate neutral conductor meeting the requirements of NEC 250.184(A) must be installed.

001 Installation.
(1) All telecommunications installations on an end-user's property, beyond the end-user's telecommunications network demarcation point, made by a telecommunications service provider, both inside and outside of a building or structure, must conform to all licensing, certification, installation, permitting, and inspection requirements described in chapter 19.28 RCW and this chapter.
(2) Telecommunications service providers including its subcontractors and agents must install and maintain points of demarcation in conformance with Code of Federal Regulations (C.F.R.), Title 47, Chapter 1, Part 68, Subpart B, Sec. 68.105 and may not place a point of demarcation further than twelve inches within an end-user's occupied space.
(3) The telecommunications service provider must identify the telecommunications network demarcation point(s) with an identification plate or label having:
(a) The provider's name;
(b) Customer/end-user's name; and
(c) If a CWSTP is used, the option type used.
(4) The C.F.R. prescribes that telecommunications service providers must choose either a MPOE (minimum point of entry) or CWSTP (cable wire service termination policy) which regulates where demarcations are placed within a multitenant environment.
(5) A telecommunications service provider, including its subcontractors and agents provisioning service for a second provider who is not the end-user of the service, must place the point of demarcation no further than twelve inches from the nearest POP (point of presence), of the serving provider, to the eventual end-user.
(6) Telecommunications service providers must designate each building that they provide services to with labeling at the terminating point(s) of their facilities indicating:
(a) Whether the building is under a MPOE policy; or
(b) Which option of a CWSTP is in effect.
(7) The CWSTP options for demarcation placement are as follows:
(a) All telecommunications service provider facilities will terminate at one location, mutually agreed upon by the provider and the building owner or designee, upon entry into the building, normally at the lowest common serving point. All demarcations will be placed no more than twelve inches from this point. The building owner and/or tenants will provide, manage and maintain building wire and cable placed beyond this demarcation point location.
(b) The telecommunications service provider's facilities will terminate at common locations, mutually agreed upon by the provider and the building owner or designee, throughout the building (terminal rooms, utility closets, etc.). The telecommunications service provider will provide, manage and maintain the building cable and registration jacks that denote the demarcation points. The demarcation points will be placed at these locations and will be accessible to end-users at these locations. This (b) is not an option for single tenant buildings.
(c) The telecommunications service provider will terminate facilities and place demarcations at locations, mutually agreed upon by the provider and the building owner or designee, within the individually occupied units, within twelve inches or a similarly reasonable distance of cable/wire entry. The provider will provide, manage and maintain the building cable, network terminating wire and registration jacks that denote the demarcation point. This (c) is not an option for single tenant buildings.
(d) All telecommunications service provider facilities and demarcations will terminate at one location on the property, mutually agreed upon by the provider and the building owner or designee. The building owner and/or tenants will provide, manage and maintain building wire and cable placed beyond the demarcation point location.
(8) The telecommunications installer must confer with the telecommunications provider when determining the point of demarcation.
002 Definitions.
(9) "CWSTP (cable, wire and service termination policy)" is the policy of the Federal Communications Commission (FCC) and the Washington utilities and transportation commission (WUTC) prescribed by tariff that governs negotiations between building owners and telecommunications service providers regarding the configuration of POP(s) and demarcation point(s) in multitenant buildings when a MPOE policy is not elected by the telecommunications service provider.
(10) "MPOE (minimum point of entry)" is a building wiring policy of the FCC and WUTC for multitenant environment locations that can be elected by telecommunications service providers. It prescribes that the telecommunications service provider will provide a single POP for access to its network and is located either at the closest practicable point to where a telecommunications service provider's facilities (fiber, coax, or copper) cross a property line or at the closest practicable point to where the wiring enters a multiunit building or buildings. All demarcations provided for customers and end-users by the provider will be placed within twelve inches of that POP.
(11) "POP (point-of-presence)," also called a "POT (point-of-termination)," is a designated point at or near a customer premise at which a telecommunications service provider's facilities for the provision of access service ends. This can be a fiber, coax, or copper connection point. Depending on the telecommunications service provider's CWSTP with the individual building owner, demarcations may be established at the POP or at other designated locations. When the customer of a telecommunications service provider is another carrier, the demarcation will be at the closest POP to the end-user. A telecommunications service provider may have multiple POPs within a multiple tenant environment.

GeneralElectrical work permits and fees.

General.
(1) When an electrical work permit is required by chapter 19.28 RCW or this chapter, inspections may not be made, equipment must not be energized, or services connected unless:
(a) A valid electrical work permit is obtained and posted per subsection (5) of this section;
(b) The classification or type of facility to be inspected and the exact scope and location of the electrical work to be performed are clearly shown on the electrical work permit;
(c) The address where the inspection is to be made is clearly identifiable from the street, road or highway that serves the premises; and
(d) Driving directions are provided for the inspectors' use.
(2) Except as allowed for annual permits and two-family dwellings, an electrical work permit is valid for only one specific job site address.
Permit - Responsibility for.
(3) Each person, firm, partnership, corporation, or other entity must furnish a valid electrical work permit for the installation, alteration, or other electrical work performed or to be performed solely by that entity. When the original purchaser is replaced, another entity may request, in writing, written approval from the chief electrical inspector to take responsibility for the work of the original installing entity under the original permit. If permission is not granted the entity must obtain a new permit for the remaining work.
Two or more entities may never work under the same permit. Each electrical work permit application must be signed by the electrical contractor's administrator (or designee) or the person, or authorized representative of the firm, partnership, corporation, or other entity that is performing the electrical installation or alteration. Permits purchased electronically do not require a handwritten signature. An entity designated to sign electrical permits must provide written authorization of the purchaser's designation when requested by the department or city that is authorized to do electrical inspections.
(4) Permits to be obtained by customers. Whenever a serving electrical utility performs work for a customer under one of the exemptions in WAC 296-46B-925 and the work is subject to inspection, the customer is responsible for obtaining all required permits.
(5) Except as allowed for Class B permits, where an electrical work permit is required, the work permit must be obtained and posted at the job site or the electrical work permit number must be conspicuously posted and identified as the electrical work permit number on or adjacent to the electrical service or feeder panel supplying power to the work prior to beginning any electrical work and at all times until the electrical inspection process is completed.
Exceptions:
(a) For an owner, an electrical work permit for emergency like-in-kind repairs to an existing electrical system(s) must be obtained no later than the next business day after the work is begun.
(b) For an electrical contractor, in a city's jurisdiction where the city is authorized to do electrical inspections and does not have a provisional permit system, an electrical work permit for emergency like-in-kind repairs to an existing electrical system(s) must be obtained and posted, per the city's requirements at the job site no later than the next business day after the work is begun.
(6) Fees must be paid in accordance with the inspection fee schedule in Part C of this chapter. The amount of the fee due is calculated based on the fee effective at the date payment is made. If the project is required to have an electrical plan review, the plan review fees will be based on the fees effective at the date the plans are received by the department for review. In a city where the department is doing inspections as the city's contractor, a supplemental fee may apply.
Permit - Requirements for.
(7) As required by chapter 19.28 RCW or this chapter, an electrical work permit is required for the installation, alteration, or maintenance of all electrical systems or equipment except for:
(a) Travel trailers;
(b) Class A basic electrical work which includes:
(i) The like-in-kind replacement of lamps; a single set of fuses; a single battery smaller than 150 amp hour; contactors, relays, timers, starters, circuit boards, or similar control components; one household appliance; circuit breakers; single-family residential luminaires; a maximum of five snap switches, dimmers, receptacle outlets, thermostats, heating elements, luminaire ballasts or drivers/power supplies for single LED luminaires with an exact same ballast or driver/power supply; component(s) of electric signs, outline lighting, or skeleton neon tubing when replaced on-site by an appropriate electrical contractor and when the sign, outline lighting or skeleton neon tubing electrical system is not modified; one ten horsepower or smaller motor.
For the purposes of this section, "circuit breaker" means a circuit breaker that is used to provide overcurrent protection only for a branch circuit, as defined in NEC 100.
(ii) Induction detection loops described in WAC 296-46B-300(2) and used to control gate access devices;
(iii) Heat cable repair; and
(iv) Embedding premanufactured heat mats in tile grout where the mat is listed by an approved testing laboratory and comes from the manufacturer with preconnected lead-in conductors. All listing marks and lead-in conductor labels must be left intact and visible for evaluation and inspection by the installing electrician and the electrical inspector.
(v) The disconnection of electrical circuits from their overcurrent protection device for the specific purpose of removing the electrical wiring or equipment for disposal.
Unless specifically noted, the exemptions listed do not include: The replacement of an equipment unit, assembly, or enclosure that contains an exempted component or combination of components (e.g., an electrical furnace/heat pump, industrial milling machine, etc.) or any appliance/equipment described in this section for Class B permits.
In the department's jurisdiction, a provisional electrical work permit label may be posted in lieu of an electrical work permit. If a provisional electrical work permit label is used, an electrical work permit must be obtained within two working days after posting the provisional electrical work permit label. See WAC 296-46B-907(2) for provisional label requirements.
(c) The following types of systems and circuits are considered exempt from the requirements for licensing and permitting described in chapter 19.28 RCW. The electrical failure of these systems does not inherently or functionally compromise safety to life or property.
(i) Low-voltage thermocouple derived circuits;
(ii) Low-voltage circuits for residential garage doors and built-in vacuum systems;
(iii) Low-voltage circuits for underground: Landscape sprinkler systems, landscape lighting, and antennas for wireless animal containment fences.
For these types of systems and circuits to be considered exempt, the following conditions must be met:
(A) The power supplying the installation must be derived from a listed Class 2 power supply;
(B) The installation and termination of line voltage equipment and conductors supplying these systems is performed by appropriately licensed and certified electrical contractors and electricians;
(C) The conductors of these systems do not pass through fire-rated walls, fire-rated ceilings or fire-rated floors in other than residential units; and
(D) Conductors or luminaires are not installed in installations covered by the scope of Article 680 NEC (swimming pools, fountains, and similar installations).
(8) An electrical work permit is required for all installations of telecommunications systems on the customer side of the network demarcation point for projects greater than ten telecommunications outlets. All backbone installations regardless of size and all telecommunications cable or equipment installations involving penetrations of fire barriers or passing through hazardous locations require permits and inspections. For the purposes of determining the inspection threshold for telecommunications projects greater than ten outlets, the following will apply:
(a) An outlet is the combination of jacks and mounting hardware for those jacks, along with the associated cable and telecommunications closet terminations, that serve one workstation. In counting outlets to determine the inspection threshold, one outlet must not be associated with more than six standard four-pair cables or more than one twenty-five-pair cable. Therefore, installations of greater than sixty standard four-pair cables or ten standard twenty-five-pair cables require permits and inspections. (It is not the intent of the statute to allow large masses of cables to be run to workstations or spaces serving telecommunications equipment without inspection. Proper cable support and proper loading of building structural elements are safety concerns. When considering total associated cables, the telecommunications availability at one workstation may count as more than one outlet.)
(b) The installation of greater than ten outlets and the associated cables along any horizontal pathway from a telecommunications closet to work areas during any continuous ninety-day period requires a permit and inspection.
(c) All telecommunications installations within the residential dwelling units of single-family, duplex, and multifamily dwellings do not require permits or inspections. In residential multifamily dwellings, permits and inspections are required for all backbone installations, all fire barrier penetrations, and installations of greater than ten outlets in common areas.
(d) No permits or inspections are required for installation or replacement of cord and plug connected telecommunications equipment or for patch cord and jumper cross-connected equipment.
(e) Definitions of telecommunications technical terms will come from chapter 19.28 RCW, this chapter, TIA/EIA standards, and NEC.
Inspection and approval.
(9) Requests for inspections.
(a) Requests for inspections must be made no later than three working days after an entity completes its electrical/telecommunications installation or one working day after any part of the installation has been energized, whichever occurs first.
(b) Requests for after hours, weekend inspections, or temporary installations that will be energized for less than 48 hours must be made by contacting the local electrical inspection supervisor at least three working days prior to the requested date of inspection. The portal-to-portal inspection fees required for after hours or weekend inspections are in addition to the cost of the original electrical work permit.
(c) Inspections for annual electrical maintenance permits and annual telecommunications permits may be done on a regular schedule arranged by the permit holder with the department.
(10) Inspections will not be made until all permit fees are paid in full.
Permit - Duration/refunds.
(11) Electrical work permits will expire one year after the date of purchase unless permission is granted by the chief electrical inspector or when the permit is closed or completed by the inspector. Refunds are not available for:
(a) Expired electrical work permits;
(b) Electrical work permit fee items, within the department's jurisdiction, where the electrical installation has begun or an inspection requested for that work; or
(c) The first twenty-five dollars of each permit purchase - Application fee.
All refund requests must be made using the Request for Refund application form.
Permit - Annual telecommunications.
(12) The chief electrical inspector or city that is authorized to do electrical inspections can allow annual permits for the inspection of telecommunications installations to be purchased by a building owner or licensed electrical/telecommunications contractor. The owner's full-time telecommunications maintenance staff, or a licensed electrical/telecommunications contractor(s) can perform the work done under this annual permit. The permit holder is responsible for correcting all installation deficiencies. The permit holder must make available, to the electrical inspector, all records of all the telecommunications work performed and the valid electrical or telecommunications contractor's license numbers for all contractors working under the permit. Upon request, the chief electrical inspector may allow the annual permit to be used for multiple worksites or addresses.
Permit - Annual electrical.
(13) The chief electrical inspector or city that is authorized to do electrical inspections can allow annual permits for the inspection of electrical installations to be purchased by a building owner or licensed electrical contractor. This type of permit is available for commercial/industrial locations employing a full-time electrical maintenance staff or having a yearly maintenance contract with a licensed electrical contractor. Upon request, the chief electrical inspector may allow the annual permit to be used for multiple worksites or addresses.
The permit holder is responsible for correcting all installation deficiencies. The permit holder must make available, to the electrical inspector, all records of all electrical work performed.
This type of electrical permit may be used for retrofit, replacement, maintenance, repair, upgrade, and alterations to electrical systems at a plant or building location. This type of permit does not include new or increased service or new square footage.
Permit - Temporary construction project installations.
(14) For temporary electrical installations, the department will consider a permit applicant to be the owner per RCW 19.28.261 under the conditions below:
Any person, firm, partnership, corporation, or other entity registered as a general contractor under chapter 18.27 RCW will be permitted to install a single electrical service per address for the purposes of temporary power during the construction phase of a project, when all of the following conditions are met:
(a) The installation is limited to the mounting and bracing of a preassembled pole or pedestal mounted service, the installation of a ground rod or ground plate, and the connection of the grounding electrode conductor to the ground rod or plate;

GeneralElectrical work permits and fees.

General.
(1) When an electrical work permit is required by chapter 19.28 RCW or this chapter, inspections may not be made, equipment must not be energized, or services connected unless:
(a) A valid electrical work permit is obtained and posted per subsection (5) of this section;
(b) The classification or type of facility to be inspected and the exact scope and location of the electrical work to be performed are clearly shown on the electrical work permit;
(c) The address where the inspection is to be made is clearly identifiable from the street, road or highway that serves the premises; and
(d) Driving directions are provided for the inspectors' use.
(2) Except as allowed for annual permits and two-family dwellings, an electrical work permit is valid for only one specific job site address.
Permit - Responsibility for.
(3) Each person, firm, partnership, corporation, or other entity must furnish a valid electrical work permit for the installation, alteration, or other electrical work performed or to be performed solely by that entity. When the original purchaser is replaced, another entity may request, in writing, written approval from the chief electrical inspector to take responsibility for the work of the original installing entity under the original permit. If permission is not granted the entity must obtain a new permit for the remaining work.
Two or more entities may never work under the same permit. Each electrical work permit application must be signed by the electrical contractor's administrator (or designee) or the person, or authorized representative of the firm, partnership, corporation, or other entity that is performing the electrical installation or alteration. Permits purchased electronically do not require a handwritten signature. An entity designated to sign electrical permits must provide written authorization of the purchaser's designation when requested by the department or city that is authorized to do electrical inspections.
(4) Permits to be obtained by customers. Whenever a serving electrical utility performs work for a customer under one of the exemptions in WAC 296-46B-925 and the work is subject to inspection, the customer is responsible for obtaining all required permits.
(5) Except as allowed for Class B permits, where an electrical work permit is required, the work permit must be obtained and posted at the job site or the electrical work permit number must be conspicuously posted and identified as the electrical work permit number on or adjacent to the electrical service or feeder panel supplying power to the work prior to beginning any electrical work and at all times until the electrical inspection process is completed.
Exceptions:
(a) For an owner, an electrical work permit for emergency like-in-kind repairs to an existing electrical system(s) must be obtained no later than the next business day after the work is begun.
(b) For an electrical contractor, in a city's jurisdiction where the city is authorized to do electrical inspections and does not have a provisional permit system, an electrical work permit for emergency like-in-kind repairs to an existing electrical system(s) must be obtained and posted, per the city's requirements at the job site no later than the next business day after the work is begun.
(6) Fees must be paid in accordance with the inspection fee schedule in Part C of this chapter. The amount of the fee due is calculated based on the fee effective at the date payment is made. If the project is required to have an electrical plan review, the plan review fees will be based on the fees effective at the date the plans are received by the department for review. In a city where the department is doing inspections as the city's contractor, a supplemental fee may apply.
Permit - Requirements for.
(7) As required by chapter 19.28 RCW or this chapter, an electrical work permit is required for the installation, alteration, or maintenance of all electrical systems or equipment except for:
(a) Travel trailers;
(b) Class A basic electrical work which includes:
(i) The like-in-kind replacement of lamps; a single set of fuses; a single battery smaller than 150 amp hour; contactors, relays, timers, starters, circuit boards, or similar control components; one household appliance; circuit breakers; single-family residential luminaires and line voltage smoke or carbon monoxide alarms; a maximum of five snap switches, dimmers, receptacle outlets, thermostats, heating elements, luminaire ballasts or drivers/power supplies for single LED luminaires with an exact same ballast or driver/power supply; component(s) of electric signs, outline lighting, or skeleton neon tubing when replaced on-site by an appropriate electrical contractor and when the sign, outline lighting or skeleton neon tubing electrical system is not modified; one ten horsepower or smaller motor.
For the purposes of this section, "circuit breaker" means a circuit breaker that is used to provide overcurrent protection only for a branch circuit, as defined in NEC 100.
(ii) Induction detection loops described in WAC 296-46B-300(2) and used to control gate access devices;
(iii) Heat cable repair; and
(iv) Embedding premanufactured heat mats in tile grout where the mat is listed by an approved testing laboratory and comes from the manufacturer with preconnected lead-in conductors. All listing marks and lead-in conductor labels must be left intact and visible for evaluation and inspection by the installing electrician and the electrical inspector.
(v) The disconnection of electrical circuits from their overcurrent protection device for the specific purpose of removing the electrical wiring or equipment for disposal.
Unless specifically noted, the exemptions listed do not include: The replacement of an equipment unit, assembly, or enclosure that contains an exempted component or combination of components (e.g., an electrical furnace/heat pump, industrial milling machine, etc.) or any appliance/equipment described in this section for Class B permits.
In the department's jurisdiction, a provisional electrical work permit label may be posted in lieu of an electrical work permit. If a provisional electrical work permit label is used, an electrical work permit must be obtained within two working days after posting the provisional electrical work permit label. See WAC 296-46B-907(2) for provisional label requirements.
(c) The following types of systems and circuits are considered exempt from the requirements for licensing and permitting described in chapter 19.28 RCW. The electrical failure of these systems does not inherently or functionally compromise safety to life or property.
(i) Low-voltage thermocouple derived circuits;
(ii) Low-voltage circuits for residential: Garage doors and built-in vacuum systems;
(iii) Low-voltage circuits for underground: Landscape sprinkler systems, landscape lighting, and antennas for wireless animal containment fences.
For these types of systems and circuits to be considered exempt, the following conditions must be met:
(A) The power supplying the installation must be derived from a listed Class 2 power supply;
(B) The installation and termination of line voltage equipment and conductors supplying these systems is performed by appropriately licensed and certified electrical contractors and electricians;
(C) The conductors of these systems do not pass through fire-rated walls, fire-rated ceilings or fire-rated floors in other than residential units; and
(D) Conductors or luminaires are not installed in installations covered by the scope of Article 680 NEC (swimming pools, fountains, and similar installations).
(8) An electrical work permit is required for all installations of telecommunications systems on the customer side of the network demarcation point for projects greater than ten telecommunications outlets. All backbone installations regardless of size and all telecommunications cable or equipment installations involving penetrations of fire barriers or passing through hazardous locations require permits and inspections. For the purposes of determining the inspection threshold for telecommunications projects greater than ten outlets, the following will apply:
(a) An outlet is the combination of jacks and mounting hardware for those jacks, along with the associated cable and telecommunications closet terminations, that serve one workstation. In counting outlets to determine the inspection threshold, one outlet must not be associated with more than six standard four-pair cables or more than one twenty-five-pair cable. Therefore, installations of greater than sixty standard four-pair cables or ten standard twenty-five-pair cables require permits and inspections. (It is not the intent of the statute to allow large masses of cables to be run to workstations or spaces serving telecommunications equipment without inspection. Proper cable support and proper loading of building structural elements are safety concerns. When considering total associated cables, the telecommunications availability at one workstation may count as more than one outlet.)
(b) The installation of greater than ten outlets and the associated cables along any horizontal pathway from a telecommunications closet to work areas during any continuous ninety-day period requires a permit and inspection.
(c) All telecommunications installations within the residential dwelling units of single-family, duplex, and multifamily dwellings do not require permits or inspections. In residential multifamily dwellings, permits and inspections are required for all backbone installations, all fire barrier penetrations, and installations of greater than ten outlets in common areas.
(d) No permits or inspections are required for installation or replacement of cord and plug connected telecommunications equipment or for patch cord and jumper cross-connected equipment.
(e) Definitions of telecommunications technical terms will come from chapter 19.28 RCW, this chapter, TIA/EIA standards, and NEC.
Inspection and approval.
(9) Requests for inspections.
(a) Requests for inspections must be made no later than three working days after an entity completes its electrical/telecommunications installation or one working day after any part of the installation has been energized, whichever occurs first.
(b) Requests for after hours, weekend inspections, or temporary installations that will be energized for less than 48 hours must be made by contacting the local electrical inspection supervisor at least three working days prior to the requested date of inspection. The portal-to-portal inspection fees required for after hours or weekend inspections are in addition to the cost of the original electrical work permit.
(c) Inspections for annual electrical maintenance permits and annual telecommunications permits may be done on a regular schedule arranged by the permit holder with the department.
(10) Inspections will not be made until all permit fees are paid in full.
Permit - Duration/refunds.
(11) Electrical work permits will expire one year after the date of purchase unless permission is granted by the chief electrical inspector or when the permit is closed or completed by the inspector. Refunds are not available for:
(a) Expired electrical work permits;
(b) Electrical work permit fee items, within the department's jurisdiction, where the electrical installation has begun or an inspection requested for that work; or
(c) The first twenty-five dollars of each permit purchase - Application fee.
All refund requests must be made using the Request for Refund application form.
Permit - Annual telecommunications.
(12) The chief electrical inspector or city that is authorized to do electrical inspections can allow annual permits for the inspection of telecommunications installations to be purchased by a building owner or licensed electrical/telecommunications contractor. The owner's full-time telecommunications maintenance staff, or a licensed electrical/telecommunications contractor(s) can perform the work done under this annual permit. The permit holder is responsible for correcting all installation deficiencies. The permit holder must make available, to the electrical inspector, all records of all the telecommunications work performed and the valid electrical or telecommunications contractor's license numbers for all contractors working under the permit. Upon request, the chief electrical inspector may allow the annual permit to be used for multiple worksites or addresses.
Permit - Annual electrical.
(13) The chief electrical inspector or city that is authorized to do electrical inspections can allow annual permits for the inspection of electrical installations to be purchased by a building owner or licensed electrical contractor. This type of permit is available for commercial/industrial locations employing a full-time electrical maintenance staff or having a yearly maintenance contract with a licensed electrical contractor. Upon request, the chief electrical inspector may allow the annual permit to be used for multiple worksites or addresses.
The permit holder is responsible for correcting all installation deficiencies. The permit holder must make available, to the electrical inspector, all records of all electrical work performed.
This type of electrical permit may be used for retrofit, replacement, maintenance, repair, upgrade, and alterations to electrical systems at a plant or building location. This type of permit does not include new or increased service or new square footage.
Permit - Temporary construction project installations.
(14) For temporary electrical installations, the department will consider a permit applicant to be the owner per RCW 19.28.261 under the conditions below:
Any person, firm, partnership, corporation, or other entity registered as a general contractor under chapter 18.27 RCW will be permitted to install a single electrical service per address for the purposes of temporary power during the construction phase of a project, when all of the following conditions are met:
(a) The installation is limited to the mounting and bracing of a preassembled pole or pedestal mounted service, the installation of a ground rod or ground plate, and the connection of the grounding electrode conductor to the ground rod or plate;
(b) The total service size does not exceed 200 amperes, 250 volts nominal;
(c) The service supplies no feeders;
(d) Branch circuits not exceeding 50 amperes each are permitted, provided such branch circuits supply only receptacles that are either part of the service equipment or are mounted on the same pole;
