GFI Breaker Won't Trip with tester
 
I recently built a pole barn.
I have 3 Square D QO 20amp GFCI breakers installed with 8 to 10 outlets on each one.

The Breaker will trip with the test button on the breaker. It will not trip if I use a tester in the outlet. The tester shows that the outlets are all wired correctly.
I even tried taking my wiggys and touch from hot to ground. and still no tripping. I was told this will always cause it to trip.

I disconnected one circuit from the breaker and tried the same test in the panel. with the gfi pigtail to the neutral bar and the neutral to the neutral bar and the wiggy from the hot to the neutral bar. That finally tripped it. Obviously the circuit is no good like that to use because it can't handle a load. But it was a sanity check.
All 3 GFI breakers will not trip.

This barn has it's own Meter. I installed 3 ground rods to make sure I have a good ground. I made sure that the green screw to in the neutral bar was in so the panel is grounded.

I have run out of options. I am afraid that it will not pass inspection if the inspector can't walk up and trip it from the outlets. I am also afraid that there is no protection if there is a problem.

I have had a couple electrician friends say not to worry about it if it trips with the test button on the breaker.
I don't want to find out the hard way that it doesn't work.
Is the circuit protected? Will it pass inspection? Does it sound like I have a problem?
Any other ideas to try? I have run out of ideas.
Thanks for any help

This is the tester that you need for checking a GFCI

Yeah I already have one of those. That is what I tested it with first. Then I was told to use the Wiggy's to try and trip it because it shows more of a current differential across the neutral and the hot. Which is what the GFI is looking for.

The neutral of the circuit does not terminate on the neutral buss, it terminates on the GFCI circuit breaker.

Correct. That is how I have it.
Hot to copper screw. Neutral to Silver screw. White pigtail from breaker to the Neutral buss.

Ok if you have one of those testers did the lights turn on and show you installed it correct? If they did, did you push that button on the tester to set it off? Just asking…

Yes, All orange lights showed the wiring was correct on each outlet. Pushing the tester button did nothing.

Also as a sanity check I wired just one single outlet directly to the breaker. Straight out of the breaker box. Still would not trip using any of the listed methods.

Pushing the button on the tester did nothing? That’s supposed to trip the GFCI

Yes I know. That is the problem. I have pretty much tried everything I can think of.

Could be a faulty GFCI

All 3 of them? Brand new out of the box? Anything is possible I guess.

You could also have a lose connection somewhere…

Something to try is add a single receptacle, about 10 foot from the panel.
Use this receptacle as a test bed by connecting it to each gfci and then us the testers test button. button.

Yep in post #8 I already tried that. Like I said I am running out of ideas. I have been trying to figure this out for a few weeks now.
