Electric signal systems.

(1) Where an electrical signal system is used, all wires, attachments, and connections must be weatherproof.
(2) Electric signal systems must be properly installed and adjusted. They must be protected against accidental signaling and must be maintained in good operating condition at all times. Enough signal wire must be provided to enable good voice contact between the whistle punk and rigging crew at all times.
