I have a sub panel in my basement that has multiple GFCI circuit breakers. All the 'TEST' buttons work. However, when using a plug tester, they don't cause the breaker to 'Trip'. The tester was tried in another plug that is hooked up 'downstream' from a GFCI plug and it successfully caused the GFCI plug to trip.
UPDATE: In response to questions below:
- I can 100% confirm the outlet is connected to the breaker
- All grounds are wired correctly both at the panel and the plugs.
- I will get a picture here shortly.
- The tester used belonged to the inspector. I'm on my way shortly to get my own to confirm.
Just a note here, the breakers in question are ALL GFCI/AFCI combination breakers. Could this be why they don't trip with the tester?
UPDATE: I was able to fix one of the breakers. It turns out the White / Blank wires were reversed (According to the tester I got). Once I fixed this and then ran the GFCI tester, it worked great. I still have one more that I'm looking at will consider the 'Ground' solution proposed.
