Since I need to have it plugged in I am wondering if I can plug it in in the belly. There are two outlets in there but both only have one plug. There is one that is right next to the inverter on the right side and one that the water heater plugs into. What I would like know is what does the plug on the right side next to the inverter power. I can't see where the wire plugged into that side is going to. Does anyone have any idea what this powers?
Any suggestions on what I can do with these plugs to make sure I can keep my water line heated?
It would help you to know if the GFCI is operating on too much power draw (amps) or because there really is a ground fault. Most likely the other outlet in the basement is also on the same GFCI circuit, easy enough to check, add a lamp to that outlet with the GFCI in use, then trip it. As for the cause of tripping, you can easily separate the wires at the supply end and apply a current clamp to check load. Last resort would be change the GFCI outlet, they are cheap and fail often
