001 Mobile/manufactured homes - Inspection.
(1) All alterations to the mobile/manufactured home electrical system must be permitted and inspected.
(a) Any circuit or feeder that is fed from the pedestal or panel from an outbuilding feeding the mobile/manufactured home requires a permit from the electrical section.
(b) Any circuit or feeder that originates from the mobile/manufactured home's (i.e., red factory assembled structures label) panel and feeds an addition or equipment that is attached (e.g., garage, heat pump, or air conditioning unit) requires an FAS alteration permit.
(c) Any circuit or feeder that originates in the mobile/manufactured home panel and feeds an unattached structure or equipment (e.g., detached garage, hot tub, pool, well, septic system, yard lighting, or generation equipment, etc.) requires two inspections. An FAS permit is required for the circuit or feeder from the panel and must terminate in a J-box located under the home's exterior wall near the rim joist. A second permit is required from the electrical section for electrical work from the J-box to the equipment or structure.
