I am trying to learn this MH, as we have only had it about 3 weeks.
Over the door ( inside ) are two switched that disconnect the batteries for long term storage. If I use these to disconnect, and plug in at the house, will the batteries get charged?

Also, I know there is an adapter for 30amp cords, to plug into household current with a standard plug. Can a 50amp do the same? Is there an adapter out there for that too?

I don't know about your first question, it would depend on how your coach manufacture designed your electrical system. However, why turn the switches off at all if you can plug into house power? I leave my coach switches in the on position if I am plugged in. The only time I turn them off is when the coach will be without "shore power" for a long time.

On the second question, I have a 50 amp to 30 amp pig tail, and a 30 amp to 15 amp pig tail. These are what I use when I plug into the house power outlet.

On mine when I use the battery disconnect it will not charge the batteries.

#1 - No. The batteries will not charge. The disconnect switches do exactly that, they disconnect the batteries , same thing as physically removing the cables.

#2 - Yes. you can use the various adapters - Word of caution. Your standard 120 wall outlet is rated at 15 amps. Most extension cards will NOT handle 15 amps.

At home, we use an adapter and keep ours plugged into a standard wall outlet with a 100 ft cord. Its enough to keep the battery charged and run the lights and furnace, but not the A/C unit or the 900 watt electric heater. Check the plugs and adapters occasionally for overheating. If they fell warm or look discolored, this means your drawing to many amps thru the adapter or cord connectors.

There are also 30 to 50 adapters, which you will need at places without 50amp service. You might want to invest in a 30 amp extension cord which is far cheaper then a 50 amp cord. These come in handy in campgrounds (mostly state parks and provincial parks) where the electrical boxes are pretty far from your site. It would also address any issue like Waiter21 pointed out of normal extension cords not handling the 15 amps. If you go this route and you have a need for an extension cord then you would get by with a 15 to 30 adapter/pigtail. No need for an extension cord then as Bigd9 pointed out the two adapters also do the trick.

The correct answer to whether the switches stop the unit from charging is "maybe". Our first one did not charge, our current one does anyway. The easiest thing to do is measure the battery voltage with the cord plugged in and the switch off and on. If it does not change then it probably charges anyway.

Seems everyone forgot to ask what type of RV he has, as that could lead to a different set up answers. Especially going from 50 amp to a standard 15 amp outlet. Current wise that is.
