Could someone tell me historically since when
GFCI on all counter top receptacles have been required,
two small appliance branch circuits for the kitchen counter top receptacles has been required,
the bathroom circuit has been required to be 20A protected,
the bathroom circuit should not have any other outlets
That’s been posed here several times in the past, but you need to know something else. Just because a particular code existed during a certain point in history doesn’t necessarily mean that code was in force in your jurisdiction.
GFCI or GFI, for reasons of safety, should be installed in **all bathrooms (required since 1975), kitchens (1987), unfinished basements (1987), outside receptacles (1973). garages (1978, wet bar countertops (1993), spas and hot tubs (1978, and ****boathouses **(1987).
