Why is there a GFCI breaker in the electric panel for the bathroom shower light and exhaust fan?
Tuesday, July 24, 2018
Although there is no citation in the National Electrical Code (NEC) requiring GFCI (Ground Fault Circuit Interrupter) protection for shower lights and bathroom exhaust fans, many manufacturers specify that they be GFCI-protected as part of their installation instructions. This is likely because it was necessary for the manufacturer to get a UL listing for the equipment. Since the NEC specifies at 110.3(B) that “listed or labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling,” it is—indirectly, at least—required by NEC code.
