conduit or tubing that is continuous from the outlet or junction box inside the recreational vehicle to a weatherproof outlet box, junction box, or strain relief fitting listed for use in wet locations that is located on the underside of the recreational vehicle. The outer jacket of the flexible cord shall be continuous into the outlet or junction box.
(e) Where the flexible cord passes through the floor to an exposed area inside of the recreational vehicle, it shall be protected by means of conduit and bushings or equivalent.
Where subject to physical damage, the flexible cord shall be protected with RMC, IMC, Schedule 80
PVC, or other approved means and shall extend at least 150 mm (6 in.) above the floor. A means shall be provided to secure the flexible cord where it enters the recreational vehicle.
(Q) Prewiring for Air-Conditioning Installation. Prewiring installed for the purpose of facilitating future air-conditioning installation shall comply with the applicable portions of this article and the following:
(1) An overcurrent protective device with a rating compatible with the circuit conductors shall be installed in the distribution panelboard and wiring connections completed.
(2) The load end of the circuit shall terminate in a junction box with a blank cover or other listed enclosure. Where a junction box with a blank cover is used, the free ends of the conductors shall be adequately capped or taped.
(3) A label conforming to 551.46(D) shall be placed on or adjacent to the junction box and shall read as follows:
AIR-CONDITIONING CIRCUIT.
THIS CONNECTION IS FOR AIR CONDITIONERS RATED 110-125-VOLT AC, 60 HZ,
AMPERES MAXIMUM.
DO NOT EXCEED CIRCUIT RATING.
An ampere rating, not to exceed 80 percent of the circuit rating, shall be legibly marked in the blank space.
(4) The circuit shall serve no other purpose.
(R) Prewiring for Generator Installation. Prewiring in- stalled for the purpose of facilitating future generator installation shall comply with the other applicable portions of this article and the following:
(1) Circuit conductors shall be appropriately sized in
relation to the anticipated load and shall be protected by an overcurrent device in accordance with their ampacities. Where the generator provides overcurrent protection for the conductors, additional overcurrent protection is not required.
(2) Where junction boxes are utilized at either of the circuit originating or terminus points, free ends of the conductors shall be adequately capped or taped.
(3) Where devices such as receptacle outlet, transfer switch, and so forth, are installed, the installation shall be complete, including circuit conductor connections. All devices shall be listed and appropriately rated.
(4) A label conforming to 551.46(D) shall be placed on the cover of each junction box containing incomplete circuitry and shall read, as appropriate, either
