(A) General. Any combustible wall or ceiling finish exposed between the edge of a luminaire (fixture) canopy, or pan and the outlet box, shall be covered with noncombustible material or a material identified for the purpose.
(B) Shower Luminaires (Fixtures). If a luminaire (lighting fixture) is provided over a bathtub or in a shower stall, it shall be of the enclosed and gasketed type and listed for the type of installation, and it shall be ground-fault circuit-interrupter protected.
Many shower luminaires have a metal base and, due to low ceilings in recreational vehicles, may be easily reached by most persons under a shower or standing in a bathtub. In accordance with 551.53(B), the installation of luminaires that are listed for wet locations and have ground-fault circuit-interrupter protection is permitted above a tub or shower enclosure.
The switch for shower luminaires (lighting fixtures) and exhaust fans, located over a tub or in a shower stall, shall be located outside the tub or shower space.
