GFCI circuit breaker installation

Posted by avalon2all (My Page) on

I am trying to replace a standard 20A square D circuit breaker with a 20A square D one-pole QO/QOB circuit breaker and GFCI. The circuit is an existing circuit for our garage receptacles. Thanks to you guys on the forum I have hooked up the breaker properly (again short of hiring an electrician). I have both neutrals attached to the neutral bar and the black wire is connected to the circuit breaker.

WHAT HAPPENS: when I try to turn the breaker to the ON position, IT TRIPS ......everytime! Is there something I can do or is it time to call the electrician?

thanks for your help everyone.

. I have both neutrals attached to the neutral bar and the black wire is connected to the circuit breaker.

The GFCI works by measuring the electricity going and coming back. If you don't run the neutral through the GFCI it won't work.

thank you hendricus for the quick response.
I think I am covered there. one of the neutrals is the circuit wire that runs with the black wire to the receptacles. the other neutral is the white curly wire coming from the GFCI unit.

What hendricus tried to say was that the neutral that runs with the black wire to the receptacles does NOT go to the neutral bar. It goes to a terminal on the GFCI breaker.
If you actually have that correct, one other possibility is that this neutral is also the neutral for another branch circuit (i.e., of the other polarity).
