Giải thích
Section 410.10(D) prohibits such luminaire parts within a zone 3 feet horizontally and 8 feet vertically from the top of the bathtub rim or shower stall threshold, unless the luminaire is listed for damp or wet locations. This keeps ordinary fixtures out of reach of a person in the tub or shower.
