I've done some remodeling in my house and part of that was some re-wiring. I installed my new AFCI breakers a couple weeks ago and all but one of them worked fine. This one circuit tripped as soon as I tried to turn it on. It was like a couple other circuits I had wired with outlets and lights on it. For the time being I installed a regular breaker which worked fine while I finished the rest of the project.
Yesterday I decided to try and figure out the issue, so I installed the AFCI breaker again, except this time it didn't trip right away. I proceeded to go upstairs and test each plug with my plug tester and it indicated all the plugs were wired correctly. Just for the heck of it, I pushed the GFCI "trip" button on the top of the tester and of course nothing happened. When I finally got to the light switches, both lights on that circuit tripped the AFCI breaker when I tested them individually. I tested the lights on another AFCI circuit and everything was ok. I proceeded to check for wires touching each other somewhere or a disconnected ground, but found nothing. Out of frustration I put everything back together, and for the heck of it tried my plug tester again. This time when I pushed the GFCI test button, it tripped the AFCI breaker on all that circuits breakers. I tested other outlets on other AFCI breakers and they didn't trip.
Any ideas on what I should be looking for?
Thanks
Here are the things I tried so far
Tried switching out AFCI breakers
Tried switching out the lights on different AFCI circuits
Plug tester indicates all wired correctly
GFCI "test" button on the plug tester didn't do anything the first time. Later it trips the AFCI...not sure why?
Visually wiring looks ok (no crossed wires, no touching wires, etc)
