Do I use 110v or 220v when charging my house batteries?

[BillJinOR]

There might be some confusion here as Its not the 50amp service that gets confused by electricians It is a standard 240 volt service.with a 14-50 plug. The RV itself doesn't utilize 240 it keeps them separate for Two 120 circuits.but the receptacle is a std 240volt wiring ! no difference.
The problem comes if your putting in 30 amp service!!! 30 amp can be wired as a 3 pin 240 like on a dryer
.. THAT will fry your coach electrical as your RV as its expecting 1 leg 120 not the typical dryer 30amp 240.The 30 amp is where the problems might exist.

Ditto!!!!! I see electrical mumbo jumbo posted on these RV forums all the time. When we professionals do post the correct answer to the OP's we get followed up by more mumbo jumbo. And why are electrical posts so interesting to so many people who think they know what they are talking about.
Sorry if offended anyone but mis-wired electrical devices because of bad advice can cause fires and electrocute people.

Emma Lou, Lots of well intentioned posts here, but we may have lost sight of your original question-charging your house batteries. If you ONLY want to keep your house batteries charged, and don't want to run the air conditioning, or heater, you could simply ask your electrician to run a 15a circuit to your parking area. A 15a circuit will be plenty to charge your batteries. It will cost almost as much to run a 15a circuit as a 50a circuit, but to answer your original question, a 15a, 120v circuit would work.
I would go with the 50a, 4-wire receptacle.

I think everyone should go out and look at their 50 amp plug.

Some will be surprised that it's marked 50 amp 120/240 volts.

Then Google the many articles explaining the 50 amp service use for RV power.

Here is an another option for the 50 amp box.

Neither. You use 12v.

Thank you in advance for your help.

This would be the correct answer to the Question as to the correct VOLTAGE to use to CHARGE your House Batteries.

BUT if you are asking to get you the correct information to Plug in your New Entegra - Look this over -

http://www.janeandjohn.org/docs/50am...stallation.pdf - T

This should be very simple for any Licensed Electrician.

If he reads this thread over and shakes his head and Laughs, I'm pretty sure he understand what he is doing, and you will be fine. On the other hand if he reads this Thread and looks for guidance you might just be in trouble, as is usually the case on things electrical and RV connected there is very little actual Knowledge that is correct and given on line - If you really understand and Know electrical system they are so easy to pick out - BUT the rest is Just Plain WRONG.

Best of Luck with the New Entegra,

Not always true. There are a fair number of higher end RVs that have 240V dryers in them. Maybe also 240V induction cooktops.

The outlet is 240V and the main breaker panel is 240V. They have to be, because of the way the neutral is handled. Individual circuits after that can be 240V or 120V.

But you are not in the USA. You are in an area that distributes 240 VAC single phase probably 50 HZ as their standard so you have mods in your RV to handle it.

True but that's the problem with saying there are not ANY RVs that need 220-240v

(Quite apart from as some have pointed out those with 240v dryers and induction hobs)

Actually you need 13.2 or more volts to push current into a 12 volt battery [emoji4]
