My storage has power outlets by every RV. They all have GFCI . mine trips when it feels like it. I set my inverter to 15 amps, thinking it was too much drain, no go. My neighbor RV plugged into my side for a little while, so I assume he has the same issue. I think I read somewhere that having a GFCI downstream from another causes problems. Is that right? Is there anything to be done? I have turned the batteries off and used a batt charger off an extension cord in the past, no problem. (The problem is when I plug the 50 amp coach cord to an adapter to the 125 receptical.

If it isn't wired correctly, yes, a string of GFCIs will have problems. You should ask at your storage site for them to take a look at your GFCI outlet. It might be wired incorrectly causing yours to pop. The GFCI might just be faulty also. Either way, or something else, ask them to take a look at it for you.

Sometimes RV's don't play nice with GFCI.

Do you have an absorption type fridge? One thing you might try is turning off the refrigerator, pulling the fuse, turn the breaker off.

If the GFCI doesn't trip right when you plug in, what is cycling on/off at a later time?

These trip when an imbalance of current between the Neutral and Line exists, in the USA they trip with 5 milliamps of current... and because everything is connected to one circuit for storage power... appliances, devices, and cords with 1 or 2 mA of current leakage, will not individually trip the GFCI, but together, they can.

Also remember that electricity travels in a circuit and will attempt to return to origin using the path of least resistance. When that path is interrupted or fails, current will still seek a return path.

Mike Sokol draws pictures of current flow to help him find the places bad things could be happening. It's a good thing to emulate.

GFCIs in strings works (I just looked at a string of 3 in a row that were fine). The trick with a string is figuring which one tripped. In storage, I would turn off all the AC circuit breakers except the one for the converter to keep the battery charged up. You can add breakers to see which is the trouble maker.

Oh, that's a great idea, thanks.
