Of course you can. You can put a GFCI anywhere you want.
Thanks. I should have said that I wanted to make sure it wasn't required to be AFCI.Of course you can. You can put a GFCI anywhere you want.
Thanks, that's good info to know. The house was built around 1930, and aside from a heavy up in 1985 and a few relatively newer AC cables installed around that time, the wiring is mostly old BX cable with bonding strips. None of the receptacles were GFCI protected until I just started adding them.Any receptacle over a counter and less than 20 inches above is considered to be serving the countertop. Depending on the age of the house it should have already been gfi protected.
Thanks. None of the existing receptacles in the house were GFCI protected (either directly, from upstream receptacles, or breakers). But I do have a GFCI/receptacle tester and I'm using it as I install GFCI receptacles to make sure that they (and downstream receptacles that are connected to the GFCI load) are working properly.This is the one time it is nice to have a GFCI/receptacle tester. Plug it in, push the button. If the receptacle goes dead, it is already GFCI protected (assuming circuit is properly grounded).
