National Electrical Installation Standards

Standards as High as Your Own

Tuesday, May 16, 2023


Hello Charlie, we are seeing more and more lighted mirrors being installed in dwelling unit bathrooms. There are a couple of questions that come up when we install these units. (1)-Would a mirror/light combo mounted on the wall over a bathroom counter, require GFCI protection? (2)-If the mirror/light combo also has a factory installed receptacle built into it, does it require GFCI protection and is it required to be supplied by the 20A separate circuit required for bathroom the bathroom receptacle.

Thanks in advance for your input, Ben Mellows


Hi Ben, good questions. The NEC® would not require GFCI protection for a light/mirror combination unit. However, if the light/mirror unit can extend into the tub/shower space as defined in 410.10(D), then it must be marked as suitable for damp or wet locations, and if it is subject to shower spray it must be suitable for wet locations. If the light/mirror unit also has a factory installed receptacle, it would could not be used to comply with the bathroom receptacle requirement found in Section 210.52(D)require GFCI protection in accordance with Section 210.8(A), it would not be required to be on a 20A circuit, as Section 210.52(1)
