When I plugged my 30 amp plug to the recepticle, I HAD power inside. The microwave LED was lit. At that point I tried plugging in a tv and as soon as I plugged it in it stopped flowing current immediately. I then suspected something wrong so I started inspecting wiring. The 30 amp recepticle was wired correctly with 2 hot wires and a groundIn the RV world, the correct receptacle has one terminal to power (usually black), one terminal to neutral (usually white), and one terminal to ground. NOT two hot wires to the receptacle.. When I checked the breaker I found a double 30 amp breaker with one hot wire and one neutral wire connected.Where is this 30 amp breaker located, in the RV or in the load center of the house? A double breaker has two hot wires, not a neutral and a hot. Therefore I had 220 going to my rv. At that point we changed to a single 30 breaker.What happened with that other wire that was attached to the double pole breaker? Powered back up and all was fine. But the microwave has no power, the refrigerator (I think) is running on gas. (no "on" light only auto)it killed the tv that I was plugging in but everything appears to be working except half of the cabin lighting does not come on. The hotwater heater works, the a/c works, the heat works and half of the lights work. Any ideas about the refrigerator and microwave? None of the breakers in the breaker panel tripped......Havent checked any fuses and don't know where to start. Any help would be greatly appreciated.

The lights are powered by the 12V system. Look on the 12V side for a blown fuse or possibly a burnt wire near the converter. It may be that one of your primary battery fuses took a hit, also. I would just check all fuses and breakers for function.

I hope you have the AC side up to par, maybe you know an electrician that could take a look to confirm that.

Steam,

I worked for years as a ship's electrician and a lot of what you wrote makes no sense..

Did you actually measure ~220V anyplace? Or is this just an assumption based on what you saw in the panel.

An RV-30 receptacle should have: A Ground, A Neutral, and a Hot terminal. If the breaker it is on has a connection to the neutral, then I would expect it to also have a test and reset buttons because it is a GFCI. Many of the older GFCI were in a double breaker body.

I suspect you have other problems you have not yet located. I suggest that you drop your shore power connection and open the MH AC distribution panel and check every screw for tightness and then do some checking inside there.

The house lights on every RV I have known run from the house battery bank. Again, check fuses and connections there before you do anything else.

I did a lot of this stuff before the depression hit. I have seen a lot of terminals come loose on their own. RVs are worse than boats for this.
