Giải thích
Section 410.10(A) requires luminaires installed in wet locations to be marked 'Suitable for Wet Locations' and installed so water cannot enter or accumulate in wiring compartments or lampholders. A 'damp locations' marking is not sufficient for a wet location such as one exposed to rain or hose-down.
