Electrical Issue

[JohnGrande]

Ok, so I have a 2006 Keystone Springdale 298bh that has been fine with no issues for a month now the way I have it set up. I have a 100' 115v 10 gauge extension cord running from a GFI outlet from my house to a 30amp adapter connected to the trailer's power cable. We have a lot of rain last night and woke up to the GFI at the house tripped and when resetting it would not stay. So I shut all circuit breakers in the camper off. and the GFI stayed reset then I turned on each breaker one by one seeing which circuit is tripping the GFI. All breakers turned on without tripping the GFI except for the GEN (General Circuit) breaker. Will someone please help? I would love a wiring diagram if anyone has one.

Update so when I took the panel cover off the GNR circuit has two wires going to it one to the inverter and one to the (I'm assuming) circuit with all the none GFI outlets. When I leave just the inverter connected and flip the GEN braker on all is well and the GFI on the home does not trip. So can anyone tell me what is on that other circuit? It looks to go out the back of the panel over the hot water tank under the oven and then into the wall where the fridge is and up.

Welcome to the forum

You won’t find any wiring diagrams or any schematics for that matter. The GEN breaker serves the CONverter and several plugs. If your troubles started after a heavy rain I would look at any exterior plugs first. They should be on a GFI circuit but there’s no telling.

You can use a plug checker to test which plugs are on the circuit in question, and after that it’s a matter of looking for moisture I think. You could remove the wire going to the converter to rule it out.
