I have kitchen outlets that have one breaker powering the top outlets, and a separate breaker powering the bottom outlets with the tab broke off on each outlet. There are a total of 7 different outlets wired up the same way.
I wanted to have the outlet GFCI protected but did not know how I could use GFCI outlets and have the top of bottom of the outlets be powered but two different breakers. I bought two 20 amp GFCI breakers to change out the original breakers.
That is when I found out that I had one 12/3 wire with black, red, white, and ground wires. I tried to use two different GFCI breakers by trying to wire nut two wires off of the white wire so that I had a white for each GFCI breaker. When I turned on one of the breakers it was fine, but when I turned on the second breaker it tripped both breakers.
I thought that I might have to buy a double pole 20 amp GFCI breaker in my situation to make this work. I am not positive how double pole breakers work.
- Will I then have 240 volts instead of 120?
- Do I have to check every outlet to make sure they did not have black and red on same top or bottom circuit?
- Will I have 20 amps off of each side?
