I am currently working on a building for the military in Afghanistan. It's an ablution block, consisting of showers, toilets, and sinks. The electrical portion has ended up being surface mounted EMT, as the building is constructed of solid concrete walls. As it happens, a suspended ceiling has been installed. The military has consultants that supervise these projects. The consultant is telling me that all of the boxes above the suspended ceiling, cannot be steel 4 square boxes, and need to be weatherproof bell boxes, because the area above the suspended ceiling is considered to be a "damp location??" There is no plumbing in the ceiling void, nor will steam travel into the void. I'm pushing for 4 squares, he wants weatherproof, am I in the wrong?
