Electric power problem

Hi Everyone
Recently purchased a 2012 Allegro Breeze. We have it plugged into shore power turned on the air in both the living area and bedroom then left for a couple of hours. when we returned to the motorhome the air conditioning, refrig, and most of the power was off with the exception of a few recepticles. I tested the shore power and it has 220. The main house breaker is not tripped. (I reset it anyway) I turned on the generator and still got no lights or refrig. The owners manual says to check the generator breaker. (anybody know where it is?) I don't know much about these .... at a loss. I did notice that a little box that says intell battery charger/converter was not making noise as it usually dose. The owners manual also says that there is a breaker within 18 inches of the converter or batteries and I can't seem to find that either. Anybody ever run into this problem?

Assuming you have 50A service, you should never see 220VAC on one leg of the 4-prong receptacle you are plugged-into; if that is what happened in your instance, many appliance will be/has been permanently damaged. If you plugged into a 220VAC 3-prong dryer receptacle you just learned an expensive lesson; very few MH's are designed for 220VAC service inside. Their breaker panel is designed differently than an RV with only 120VAC inside service.

How did you test it? Confirm, please, which pins on the connect are for which conductor. I'm not being a condescending jerk, I'm trying to confirm your methodology.


As Ray points out, you shouldn't measure 220V (or 240V) at any Edison outlet in/on the coach, and you should measure 240V only between the 2 hot legs of the shore power outlet; 120V between neutral and either hot leg; about 0V between neutral and ground.

Assume you checked the main breakers on the house panel but did you check the main breakers in the coach. If all was working when you left the coach it wasn't hooked up wrong.

Thanks for your response curtsr. I checked the main breaker on the panel inside the coach. It's located in the bathroom area. I know this is really stupid but what house panel ? There's a panel on the outside below the drivers area but I only see fuses in that area. All tested good.

By house I mean the breakers on the shore power but you said that is good on previous post. Turn the main breakers off then back on in the coach to make sure they haven tripped, sometimes they look normal but are in fact tripped. Finally it could be a problem with the transfer switch. If you could check voltage going to the coach main breakers that would confirm if transfer switch is good. Generator breaker is on the generator some models are behind the service cover.

Also,the OP should NEVER switch power sources while the electrical system is under a heavy load; ie air conditioner, microwave, etc. It is hard on the transfer switch and can lead to early failure.

I had a similar situation earlier this year with my rig. When I hooked up to shore power I only had few circuits energized. I didn’t have any circuits from my EMS energized, A/C, Washer/ Dryer or HW tank!
I did have both hot legs at my main! I called the tech supporter the EMS supplier and they told me to disconnect from shore power and turn everything off. Then to disconnect the connectors going to the EMS circuit board for a minute or two to “reboot” the EMS! Went ahead and did this then everything came up once brought the shore power back up!!
