My RV charged just fine in my garage on a GFI outlet until I replaced the converter with an inverter/charger. As soon as I plugged into my house power, the outlet tripped.

My RV has a Prosine 2.0 inverter/charger, and it has an option to defeat the internal automatic neutral bond which caused the GFI outlet used to feed the RV to trip. I set the option to defeat the automatic bond and no more external GFI tripping.

I had an intermittent short in an outside plug in my curb side storage bay. Water had gotten inside the plug, and the wires were corroded. Until it went completely bad, took a while to find it.

Sounds like a faulty installation to me. For a built in inverter the AC output neutral and hot should be isolated from the rest of the rig by a ATS and the neutral and ground for that output circuit should be bonded in the inverter. This bonding will not in any way effect the shore GFI because of the ATF isolation.

You must be using an adapter or some type of pigtail to plug into a household outlet I would suggest you try another adapter.

With the main breaker off you could still have a problem with your power cord that would trip the GFCI.

Thanks to all of you who responded to my original inquiry. When trouble shooting a new problem, I failed to look at the obvious; "what's different than the last time it worked". My wife had turned on the refrigerator before I moved it. A couple of you suspected the refrigerator and that finally rang a bell in my dense head. After turning off the refrigerator, the ground fault stopped tripping. It did not trip after the refrigerator was turned on after the power was turned on in the coach.

It worked all week although the campsites did not have GCFI and it is still working now that I am back home. Could be there was some moisture in the refrigerator circuits.

Do you have a Norcold 1200 series refer? If so, one of the 2 heat elements is your problem. Replace BOTH. Doug
