Rainy and 40ish all weekend here ...
We've had a few instances over the last couple of years with the GFI popping. I read somewhere that GFIs over the years get that way.
We had a lot of rain here last month.
The GFI popped in the trailer & wouldn't reset.
Bought a new one & installed. It popped & wouldn't reset.
Started pulling outlets and replacing. I wanted to pull them anyway to trace and do some rewiring. The outlets were the pos kind that the wires push into.
After I opened the exterior outlet and removed the pos outlet the GFI problem went away. There seemed to be a couple of excess "cuts" in the insulation and I speculate that moisture trapped in there was the culprit.
You could have a moisture problem that is popping the GFI. If the problem persists at home, a hair drier on the exterior outlet(s) might help. If you wind up pulling and replacing the exterior outlet beware that it is not a simple job. My pos outlet was secured by plastic "ears". They didn't work with a real outlet. I wound up getting a "mud plate", cutting it down enough to fit in the hole and securing the new outlet to that.
Rewiring:
New "real" box and outlet for the refrig connected to the same circuit breaker as the water heater. Now I can kill the AC, MW, WH & refrig when dry camping.
All wall outlets connected to one circuit breaker through a transfer switch so they can be powered by my inverter. Also installed the inverter.
New "real" box and outlet for the Power Converter and a dedicated circuit breaker for it. The Power Converter lives under the stove and the outlet is behind a door. This gives me a outlet on a separate circuit for the electric heater, toaster oven or coffee pot if they cause problems on the same circuit as TV & etc.
Mystery:
There was a box under the pos outlet for the power converter with a blank cover. Inside the box a ac house wire came in, was connected to a rubber covered cable that went under the floor. I have no clue what that is. It is not anything mentioned above.
