When plugging our 2004 Arctic Fox 1150 camper into shore power, the GFI we are plugging into will trip. We found one exterior plug that the wire was a little loose on and we have fixed that. We checked every plug all is well, unplugged the microwave and plugged in still tripped. Not sure where to test next. When plugging into shore power things such as Refri, AC, plugs and Microwave come into play. Is there something else we are not thinking about that would be causing the GFI plug to trip??Thanks in advance!!! Tripping in Seattle

Turn off all circuit breakers in the rig, then see if it trips.If it does not trip, turn on main breaker in rig(if equipped). Then turn on each branch breaker to see what circuit problem is on.Unplug the refer from the exterior access. it is possible that the 120 volt AC heater element is going to groun.

If you have an inverter.. Was the neutral bonded to ground (unbond it)Some converters will trip a GFCI if the battery is hungrySome ... If the battery is fullAnd of course the above suggestions as well.I have heard of junction boxes under slide outs filling with water as well. The patio outlet (outside outlet) is another suspect, The list goes on.

I just went through this with my Arctic Fox. I found the problem in the junction box where the outside cord attaches to the trailer's electrical wiring. The attachment is made with wire nuts and the neutral connection had come loose and melted the wire nut and the insulation about 1" back from the connection. I made the repair and all was good.The use of wire nuts is problematic. Far better is to solder or use properly crimped on connections. I may go back and do that.Good luck.

Awesome suggestions. Actually did try turning breakers off one at a time, still tripped.We did have a loose wire in the outside plug so we replaced that still issue.Haven't checked the converter but will be doing that shortly. Thank you everyone for the quick and great responses!!!Will keep ya posted
