Question Electrical Issues.

Have an RV plugged into a 220 station at a camp. Everything running fine off the power until this morning when all the lights dimmed and the A/C stopped working. The microwave and T.V. were still usable, since they can only operwate off of outside power or a genrator, but the power to the the fridge stopped. We ended up turning the "car" portion of the RV on, the engine in the driving area, and everything went back to normal, even after shutting it off. So that is where we stand now, but what exactly happened, and what can we do to prevent it from happening again?

It would help to know what kind of rig you have. Has there been an electrical failure within the campground. Do you have a generator. Do things work fine off your genny. Do you have a voltage meter.

Lots of questions before we can help.

Common problem, you were plugged into a 50 ampere 120 volt pedestal at the campground. All a/c appliances still worked because it was 120 volt supply. It also supllies the power to the ac-dc "converter" when that fails or the battery supply is interrupted, the DC 12 volt circuit in the coach go down. That sounds like what happened to you. No DC power available. Maybe the battery was cut off and for some reason the converter stop supply due to open fuse etc. When the truck was connected it supplies the 12 volt power also. You must now trace down bad or open circuit battery, bad or open circut converter etc. Can't be too hard to find now you know where to look. If you really plugged into 220 volt, you would now have alot of melted copper!

It wouldn't matter if it was 220 or not since 220 is just two 110 circuits center-tapped around neutral.

I had the same problem at my last campground. One of the two 50-amp breakers wasn't providing power, so some of your circuits work and some don't. The campground fixed it. It's strange that it still worked after your temporary work-around, but such is the nature of intermittent problems.
