So i have a 1990 Excella 29.
It has the mid bath.
My manual shows schematics as rear bath so maybe they never upgraded the manual.

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.

Any ideas?
Thanks for reading!

So in my mind, a couple things swimming around.,

-is there actually a wire problem in the walls? Or in some outlet?

-Or is it just some moisture causing a stray amount of current to trigger the breaker?

-or.. breakers do wear out

Should I order another (if available) GFI style breaker?

Should I forget the GFI and install a regular breaker?
(The manual says they normally install a regular breaker except if RV being shipped to a state that demands GFI)

Pull and check the exterior outlets for moisture intrusion if they are indeed on the same circuit as the GFCI breaker..

Assuming you like myself have had an extremely soggy last couple of months in PA heavy wind driven rain can get past the outdoor outlet covers..

I would recommend keeping the GFCI breaker, find and fix the problem. Not only is it required per NEC in wet locations such as bath, kitchen and outdoor outlets it most definitely save your life in the event of being exposed to a faulty appliance..

There are several possible answers
#1 suspect is the outside outlet... Full of water in many cases
Sometimes the fridge is on the GFCI (Need not be but they do it anyway) and sometimes the heat element in the fridge. can short to ground. or in my fridge (Which was NOT on the GFCI) there was a terminal board that if you did not follow instructions got wet and would have done the trip... (Dealer did not follow directions.. I did).

Easy to check the fridge though. when the GFCI trips. does it still say "AC" or does it switch to "GAS" (or LP)? if it says AC. that's NOT a suspect.


Home was where I park it. but alas the.

Is the breaker popping or the GFCI popping?
2 different issues with generally different causes.

Breaker popping = overload (if being used), or generally live short to ground (overload again, but more and quicker)

GFCI popping = ground fault. In which case, I'd probably start with what GDEtrailer said.

You also have a 30+ year old camper and that may be a 30+ year old breaker. Both the breaker or the GFCI may be wore out.

Other possibilities, rodent damage to wires (not good and may be hard to find) could cause a ground fault or a live short.
Overloaded/burnt/melted outlet on that circuit.
Not sure if you asked what was on that circuit or were telling us, but
Barring moisture in the exterior outlet, start by disconnecting one outlet or light at a time. Then flip the breaker or GFI and see if it holds.
You may discover something by removing an outlet, or you will narrow it down to the offending outlet or appliance.

That could also be true.
I got back from Az in Jan, it was all 8 degrees at night. My poo hose froze along with the dump exit.
I bought a red heat lamp and have it under the trailer.
Plugged into the side outlet full time.

If you do not have one, they do make "in use" outdoor outlet covers which I would suggest..

HERE

They are designed to allow you to have items plugged in and the wire exits out the bottom to prevent rain from getting to the outlet and plug.

NEC requirement for new construction and retrofits..

Beats the old open clamshell "in use" ones that slammed shut as you pulled the plug out..
