Is a shower ceiling considered a wet location or a damp location? Would a fan/fixture located in a shower ceiling have to show the rating in addition to stating that it is suitable for installation above a shower (along with GFCI requirements of course)?
Here is the 2011 NEC.
410.10 (D) Bathtub and Shower Areas. No parts of cord-connected
luminaires, chain-, cable-, or cord-suspended luminaires, lighting
track, pendants, or ceiling-suspended (paddle) fans shall
be located within a zone measured 900 mm (3 ft) horizontally
and 2.5 m (8 ft) vertically from the top of the bathtub rim or
shower stall threshold. This zone is all encompassing and includes
the space directly over the tub or shower stall. Luminaires
located within the actual outside dimension of the bathtub
or shower to a height of 2.5 m (8 ft) vertically from the top
of the bathtub rim or shower threshold shall be marked fordamp locations, or marked for wet locations where subject to
So the fixtures must be marked at least damp locations.
