I'm shopping for a combination vent fan/light for a bathroom, and some of the ones I've found state this:
UL Listed for use over bathtubs and showers when connected to a GFCI protected branch circuit. 7 1/8" high housing, 4" round duct connector. Not for use over cooking surfaces. U.L. rated. If placed over bath or showers must be installed on a UFCL brand circuit.
What exactly is a "UFCL brand circuit"? I'm quite familiar with a GFCI protected circuit - is that just another term for the same thing?
