I plan to upgrade five 2-prong receptacles in our kitchen. The house was built in 1960. I will be replacing the very first receptacle in the run with a GFCI-AFI receptacle, then replacing the other 4 downstream receptacles with standard 3-prong receptacles, thereby protecting the entire circuit. My question is this: The kitchen circuit is protected by a 20 amp breaker in the panel box. But all of my new receptacles will be standard household 15 amp 3-prong receptacles. To meet code, is it allowable to use a 15 amp GFCI-AFI receptacle at the beginning of the run, or will I need to use a 20 amp GFCI-AFI receptacle since the circuit breaker itself is 20 amp? I've heard it is standard practice to use a 15 amp GFCI instead of a 20 amp GFCI receptacle since the receptacles are only 15 amp. Plus, I have no need for a 20 amp receptacle, nor have I ever, so I want to make sure I can use the 15 amp GFCI without any issues cropping up. If an experienced electrician can offer insight, I'd greatly appreciate it.
