QUESTION: I have a cursory knowledge of construction, can you elaborate on "Depends on how the house was wired. I will add that the home is a tract home, with copper wiring, built in Carlsbad, CA in the 1980's, so it is not an older home. Hopefully this will give you enough info to respond. TIA
Great. There were three iterations of the NEC in the 80s, each one with more defined requirements for GFIs.
What gauge wire was used? 12 or 14?
Are all bathroom GFIs on same circuit?
Is everything in the one bathroom on the same circuit as the GFI outlet?
What else is on the circuit with the GFI outlet?
What year was the house built?
What version of NEC was being enforced in your town [call township offices] when the house was built? It wasn't always the most recent version.
I believe it was still allowed to have GFIs fed from lighting circuits in the 80s, in which case there may be one GFI in a bathroom someplace, with all other required GFI-protected outlets fed from that one receptacle, including the grade-access receptacles on the building exterior.
Further, in the last several years, California has turned the entire licensing process on it's head. I have no idea what the requirements were where and when your house was built.
You can't go wrong if you install a twenty-amp rated GFI. It isn't overcurrent protection.
