Requirements for painting the enclosure of electrical distribution boxes
Painting the internal electrical box—the container recessed within the wall that houses the wiring connections—is strongly advised against and prohibited by electrical codes. Before picking up a brush, homeowners and property managers should research local regulations. This manual is for electronic distribution only and is designed to provide you with the most current information on the Los Angeles Department of Water and Power's (Department) service equipment and installation requirements. Every effort has been made to make this manual as complete and accurate. The NEC, 110. 12 (B) does not explicitly prohibit painting the exterior covers of panels and switchboards, but it is recommended to do so if the panel can still be opened and operated with external handles.
