I bought a Broan 455FL medicine cabinet for a bathroom. It has a single 15 amp receptacle and 2 fluorescent lights. This would be the only receptacle in the bathroom. Its a grounded outlet but not a gfci so my thought is to put a gfci breaker in at the panel. I know bathrooms need to be on a 20 amp w/12-2. So if I have 1 15 amp receptacle and 12-2 going to the bathroom, what can be done to get the medicine cabinet wired safely?
