So i have a 1990 Excella 29.

Anyway, whats on this circuit?
-battery charger
-bath outlet
-exterior outlet
-2 other interior outlets

I unplugged anything on the circuit including the charger.
Breaker still flips off.

Take wire out of breaker?
Breaker happy.

Is this a combination GFI/circuit breaker? Or are you referring to a standard circuit breaker and a downstream GFI outlet?

Assuming a combo GFI/CB

What is tripping, the GFI of the circuit breaker? There is a difference and it matters.

Don't spend money needlessly. If you removed everything on the breaker including the load wire from the breaker and it stops tripping, there is nothing wrong with the breaker. For the breaker/GFI to trip there has to be a load somewhere whether it's a shorted wire, shorted outlet, or an appliance you didn't think of. But something downstream of the breaker is leaking voltage or the GFI would not trip.

If it was me I'd take a sheet of paper and draw a rectangle on it. That's your RV. put a star where your circuit breaker box is located. Now put a circle in every place you think represents the location of an outlet.

Hook up the load wire and start with outside outlets or outlets in outside compartments. Pull the outlet cover and outlet with the power disconnected and see if you see moisture.
If no moisture or obvious damage you're going to have to figure out how to disconnect the wires (label them first) and see what outlets cause the trip. Test the CB with the outlets disconnected one at a time.

Keep disconnecting outlets one at a time until your GFI stops tripping. Once you find this oputlet, make note on your diagram of which outlets still have power, they are not suspect. Mark which outlets have no power, they are all suspect.

At the first suspect outlet remove teh outlet and wire nut the white wires together and wire nut the black wires together. If the GFI still trips you are at the wrong outlet. Keep removing and wire nutting outlets until you finally find the the outlet that is causing the trip.

If OP has self contained device outlets which doesn't require a workbox is a reality of a lot of RVs they will not be able to "disconnect" and isolate outlets.



The Romex is not cut, there are no splices, wire nuts, crimps, instead the sheathing is opened and wires are fanned out and outlet device is placed across the wires. Once the wires are in place, the outlet device is pressed together and the insulation on the wires is pierced and displaced to make electrical contact..



This is typical of many RVs, it is quick and effective means of assembling the RV. These devices also are very low profile so they easily fit in the thin walls of a RV where standard workboxes with sufficient fill capacity will not fit.

I also have found that more often than not, there is nearly zero slack or extra wire when RV manufacturers use these devices..
