GFI Breaker trips when I use the outlet

In my timer box I have three Breakers. One is for the Pool pump, one is a GFI breaker for the pool and spot lights and the other breaker (non GFI) is for the outlet next to my pool equipment. When I use the outlet my GFI breaker for my pool/sopt lights trips off. The outlet works fine after that. After i'm done I turn off the breaker to the outlet and turn the GFI one back on and everything is fine. Would anyone know what is causing the breaker to trip like that? I would think the outlet is tide into the GIF breaker some how since all outside outlet needs to be on a GFI.
Please advise.
Thank you!

Does it matter what device is plugged into the non-GFCI outlet?

I fought something similar to this for a whole season. Turns out the outlet itself had a little corrosion where the ground pin goes in. Swapped out the outlet and everything worked. The strange thing about it was that it wouldnt *always* trip, and when it did, it would run for very different amounts of time before doing so (pump could run for 2 minutes, 2 hours, or 2 days before it acted up again).

Check the outlet to see if you have any corrosion. Also check the green bonding wire to your pump, along with the other electrical connections to the equipment. Since the GFCI basically requires every last bit of juice going out to actually come back (my simple way of putting it), any small amount of corrosion, loose fittings, etc. can cause it to trip.

I have tried two different devices and they would both would trip the breaker. I will look at the ground and the outlet again. This is all new equipment. Do you think the GFI breaker could be bad? I was hoping to figure this out before I have to call the pool builder back.

This is what happened to me as well. I tried the pool pump and that tripped it. I plugged in an oscillating fan and that tripped it. Just for further proof, I plugged in a Shop Vac and that tripped it as well (keep in mind these devices would actually run for some amount of time, it wasnt like they were shorting out and tripping the breaker instantly).

I too was worried it was the breaker, but in my case it just turned out to be the outlet causing a problem.

Sounds like something is causing a shortage. Maybe water got into it? Is it outside?

There's a good chance the breaker is bad. These things are very sensitive and when they go this is how it usually happens.
