Does a bathroom exhaust fan need to be GFCI protected by code?
Tuesday, February 25, 2020
Although the National Electrical Code (NEC) does not have a requirement for a bathroom exhaust fan to be GFCI protected, it is often specified by the manufacturer in the installation instructions when the fan is over a tub or shower. This is probably because it is required by a rating organization (such as Underwriters Laboratory - UL) in order for the fan to be listed and labeled for building code approval. The GFCI protection is usually provided by a GFCI breaker in the panel.
