YOU SPEAK TRUTH BWANA! GFCI's save people's lives every day. We curse them when we're standing in the bathroom and our hairdryer trips one, but it's far better than the third degree burns that you could get if it didn't.

BTW, a very bad repair person I used to know (big fan of duct tape) used to say "I trace shorts in the wire by sticking a penny in the fuse box, then sniffing for burning insulation." Why he doesn't say that anymore? You guessed it. Electrocuted himself.

some people have reported that their replacement cnverter trips the gfci breaker.

something to try is to turn all the breakers in the trailer off and see if it still trips. if it does not trip, turn the breakers on one by one to try to isolate the circuit causing the problem.

If your problem comes back it could be the heater element in the frig you can run it on propane to get around it until repaired.

Sounds like you may have wired your 110 plug backwards should not make any difference.

The output of the inverter has netural and ground tied together most are designed this way. A work around is to run the inverter to dedicated outlets.

Should not make any difference in regards to the plug 30 or 20 popping the breaker.

I have tested all the outlets inside with 2 different 3 light plugin testers and all is good. I have also turned all the breakers off and the gfi still trips. I plugged in just the cord and the gfi didn't trip so it's not my cord. I also dissembled and cleaned the plug where the cord plugs into the trailer. I will try another 30 amp to 15 amp 110 adapters and see if that is my problem. If that isn't it what do I test next?

After reading the answers to my question I looked at my power converter where the 110 line is connected and found the problem. When I wired it, I wired it like a house with the common and grounds tied together at the breaker box on a common bonded buzz bar. There is a separate buzz for the grounds at the top in the power converter box that I didn't see, so all I have to do is move the ground wires to the correct buzz bar. Thanks for the helpful replies and again sorry to hijack this thread.

I just bought an Argosy 30 1978. When I plugged in to the shore line I noticed the 20am GFI kept tripping. I tried several times to reset...not happening. I might add I am hooked up temporarily to a 110 3 prong outlet. I have the adapter in place with a 15ft medium duty extension cord. Could this cause the tripping problem. A/C works outside outlet works. I am new to all of this. Any suggestions? Thanks.

You asked the same question over on the "How to solve tripping GFCI" thread, so this answer is also a repeatů

Since you have a GFCI circuit already in the trailer, plugging into a GFCI shore power source means you've got two GFCI's in series. Because of the internal wiring that allows a GFCI to detect a current leak, the upstream GFCI mistakenly sees the downstream GFCI as a ground fault. Turn off the breaker for your trailer's internal GFCI, and the shore power GFCI should quit tripping.

Thanks Protagonist for getting back to me. Sorry for the double post I'm new at this and wasn't sure where to post.
Anyway, the shore line is not a GFCI it is a regular 3 prong plug. I was going to replace the 20 amp GFCI breaker in the trailer today but thought I would ask for advise first. Any other thoughts?
Again thanks so much.

Sorry; I misread it, when you said the "20amp GFCI" I thought you meant your home power.

Two other thoughts:
1 - A GFCI breaker is still a breaker. It can trip if you overload it even if there's no ground fault, just like any other breaker. If so, try unplugging everything, then plug in items back in one at a time until you find which one trips it. Then do it again, in a different order, to see if the same appliance trips it when you plug it in first, or if a different appliance trips it next time. If it's the same appliance every time, there's your problem. If it's a different appliance every time, you're either plugging in too many things and overloading the circuit, or you have an internal wiring fault.

2 - Even though the breaker is a GFCI, there may be an outlet somewhere on the circuit that has a test/reset button. You may have to reset that button before you reset the breaker. My Airstream is like that.

I will check for GFCI plugs in the trailer. Off hand I don't remember seeing any. If that doesn't work then I will try your first suggestion. The wonders of electricity! Thanks again.
