Hint: Rusted fixture remnants
The camera angle for this may be a little tricky, but I took this picture looking up, while I was walking along a sidewalk, and spotted this rusted light fixture mounted underneath an awning. The bottom of the fixture has completely rusted away! We can see the ballasts and internal wiring of this light fixture because so much of the fixture has rotted away. Section 410.10(A) requires luminaires in damp or wet locations to be installed so water cannot enter or accumulate inside the fixture. Luminaires installed in damp locations such as this, must be marked as suitable for damp or wet locations. According to Sec. 110.11, unless identified for the operating environment, equipment and conductors cannot be located in damp or wet locations, or where gases, fumes, vapors, liquids, or other agents where will have a deteriorating effect on the equipment or conductors. Perhaps in this case, the proximity to the salty ocean air played a role in severely rusting this fixture since this location was at a beachside town.
