Yes it's a 20 amp breaker. I'm pretty sure it's 14/2. It has a white
jacket, I think 12/2 is a different color. A wash machine has been the
only thing on the circuit for the last few years so I'm thinking its
ok. I asked the question because when I installed the GFI recept. the
GFI tripped. Not sure if you can jumper across the 2 hot sides of the
recept. with the black wire, white on neutral etc.
