Baffled with electrical problem

What did you find that leads you to this decision? continuity and when we hooked that wire on the ceiling fan it tripped the main breaker, then we bypassed that line by running a seperate direct line and it worked fine

I still think you have some loose connections somewhere in the loom or breaker panel. I agree

What work or mods were performed prior to all of this happening, if any?
None
Why is the table light 120V? Most are 12V from the factory. Was it added later?
There are 2 lights in that are one is 12v other is 120v original factory

Sorry have to ask so many questions, just trying to understand what happened and the permanent repair.

Please check for hot skin periodically.

thanks

Great that you are on the trail to discovery. Keep at it! Trailers and RV's can be a bear to find the issues. But find them you will.

Note: your ceiling fan could be the problem. Check the motor leads.

Sounds like you may have “inadvertently” repaired the loose wire issue during the hooking up the jumper and redoing the original connection.

so what happened ?

If the living room circuit has the black (hot) and white (neutral) wires reversed on that breaker, then the breaker is opening the neutral and the fault on the black wire still goes to ground (green)

Most likely the issue if it mysteriously went away.

Here’s my take on your situation. You have isolated the problem to the wiring between your 5w connector and the breaker panel. With power disconnected and breakers off remove the main panel cover and follow the wiring to look for an overheated or chaffed wire shorting to ground. Do the same for the female outlet into which you plug your shore line. Travel and vibration may have found a way to short your hot line to the frame or to the ground wire. I had a burned connection at my converter box that caused a short. It took a while to find but once fixed everything now works.
Be careful with your service power most 30 amp systems are 120 volt and not 220 as might be thought given the plugs and outlets we see. A mistaken connection to a 220 home circuit will quickly blow the converter for your 12volt lights and fixtures.

carl oh;
Are you sure the outlet (house end) is wired correctly? I concur with the other posts that it appears to be a ground fault. If it trips when the 30AM to 50A F dogbone adapter is plugged in then I would suspect an outlet being miswired. If you can test the outlet with a multimeter, I think you should find the error. If you are unsure of using a voltmeter, you could pick up a 30A to 15A adapter block and an 3 light outlet tester. Just plug it in and see what the lights tell you. The tester should read the same as from an outlet inside your house.

I'll keep an eye on this thread and see what you post. ... Swampy

So is the ceiling fan and the outlet.

A loose wire most likely would not make the ground wire hot, that's a serous problem and needs to be figured out

You might have a problem with the transfer switch it converter, and the inverter if it has one. Think of electricity as a river and work your way upstream and you'll find your problem. A set of wiring diagrams would help.

All - If I was a betting man, I suspect he had a lose connection, which inadvertently was fixed with all the checking and putting back together. My MH new, in 08, friend told me about IRV2 then, so I started reading posts about my model. Found out the Electrical QA was horrible, so having some electrical training then, took it upon myself to check, every electrical connection on the 120V AC and 12V DC connections, over 65% of them were lose. I suggest to all annually, you check all of them, as we own "earthquakes going down the road". When I got to the Genset to house connection, one of the wire nuts just fell out of the box, they used the wrong size for that connection. I put the correct ones on, used Scotch 33 Rubber Tape, then Scotch 88 over that, they won't come lose again.

Obviously you have a short. Don't just turn off a rv breaker but pull the breakers one at a time until you ground is not longer hot. This doesn't mean the breaker is bad, but that somewhere in that circuit there is the short. It could be a wire chewed by a mouse, a bad outlet or any item on that circuit. Start at the nearest application in the circuit, discount the wires from the breaker, reinstall the breaker and recheck for a short. If there is no short move on to the next application and repeat the process. Once you have a short again the short is between that application and the previous application. If the previous application is an outlet replace that outlet. If you still have a short then the wire has shorted. Sometime this is caused by a mouse chewing on you wire. However i have heard of a staple in the wire and it not shorting until later after all the shaking of moving down the road. Good luck.

You can NEVER have a hot ground - that's really dangerous!

Here's what I'd try...
1) Flip all the breakers in your vehicle off.
2) Flip them on, one at a time and check to see if the main breaker has flipped. If it hasn't, turn that breaker back off and proceed to the next breaker.
3) If (hopefully when) you flip a breaker on, and the main breaker trips, then you've found the faulty circuit. Investigate it, and find the fault. In any case, LEAVE IT OFF until you've found and fixed the fault.

This is dangerous. If you've got a hot ground, you can get electrocuted! Please be careful!
