The fact that you can plug in with all the breakers off in the coach makes you want to say the problem is right in the electrical panel of the coach. Make sure the neutral and grounding conductor aren't tied together in there. It would be interesting to test between the grounding prong and the neutral prong of your RV cord and see if there's any resistance between the two. There should be none. I'd also take that meter with the main off and make sure you're getting power to the line side of the main breaker and that the GFCI isn't tripping before you think it is. It's amazing the advice that RV dealerships will hand out. Removing the GFCI from your garage is not the answer. It's like listening to the electrical guy in Menards, bad idea!

Inspection: no conductive material (copper wire, plug prongs) should be able to get wet.

Measurement: with power code disconnected from that GFCI outlet, measure between each conductor with an ohm meter. Anything connection between any two conductors that is near to or less than 20,000 ohms is a fault. A meter can help narrow down the search for that fault.

Testing: when everything is dry and the GFCI does not trip, then use a garden hose to slow wet different locations until the GFCI trips. You need not worry much about being electrocuted becaues the GFCI should trip before you can be shocked. As soon as a wet spot trips the GFCI, then you have a suspect location.

And finally, if the cable has a hole or crack, then moisture may have gotten inside. Getting inside of a cable dry before sealing it can be challenging. One popular solution was to put the break into a sealed container with rice. Over a week, rice may draw out that moisture.

One correction. Neutral and safety ground wire should not be connected anywhere until both meet at the pole. Or in this case, at the main breaker box in the house. If neutral and ground are shorted together in the coach breaker box, then that would explain a house GFCI trip and no coach GFCI trips.

Everyone keeps forgetting the fact that the garage breaker doesn't pop when the 50-A cable is plugged in and the mains are open.

That shows us that the problem is after the main, NOT in the cable.

It actually does. I adapt my 50 amp down to a 30 amp extension cord and then adapt it down to a 20 amp GFI outlet. The second I plug into 20 amp, my garage GFI pops. If I plug directly into 30 am, which I have in my RV storage barn, I have no issues in my coach. I realize I have no 30 amp GFI protection.

I guess your post #7 confused me. It stated that as soon as you turned the main breaker in the MoHo on it tripped.

When you solve this problem, please post the results. I really don't understand electricity that well and would like to hear the fault and the fix.

Thanks

Bill

Reason for tripping is layman simple. For every electron going to an RV (ie on black wire), a same electron must be returning to the house (ie on a white wire). A GFCI measures that current. For 20,000 milliamps, if five milliamps are unaccounted for, then a human life is at risk. So the GFCI cuts off current.

A GFCI measures current going out and current coming back. If not same, then current is going somewhere else; might harm a human. So a GFCI trips. A GFCI is that simple.

Brought my MH back from dealer today. Leaving on a trip tomorrow. I cannot connect to a GFI or non GFI circuit. If I connect to a GFI outside my house, the House/garage GFI trips. If I connect to a non GFI, it trips the breaker on my house electrical panel. Nothing in on in the MH. Help!!

If it's tripping the breaker on a non GFI circuit the instant you plug in, you have a direct short somewhere. I would take it back to the dealer
