Do I use 110v or 220v when charging my house batteries?
Can you tell me if I am supposed to use 110V or 220V when charging my house batteries? The sales person we purchased our RV from didn't know. We tried calling Entegra but couldn't get through to a real person. We are hiring an electrician to run power from our house to our RV and need to know what power we should tell me we need. Thank you in advance for your help.

110V! No where do you use 220. Have the electrician run a 50 amp set up for you. That consists of two 110 lines and a ground. The receptacle is entirely different fro a 220 plug. That gives you two separate 110 circuits which can then be used to power different things.

Show your rv electrical cord plug to your electrician, if he says "I've never seen that before" or "I'll have to get an adapter" or some such, get another electrician.
Its a 50a 4-wire receptacle, if he says anything else, send 'em packing.
To answer your question directly, you need 110 v to charge your batteries, not 220v.

Make sure the electrician you hire has done RV 50 amp plugs before; and have him show you this test of his work before you plug in.

Ditto! Rv plug is different than other house receptacles. I am guessing your converter,that charges your House batteries is set for 220!

I seriously doubt that ANY RVs have a charger that is set up to need 220 volts.

OK--assume you have an Entegra coach since you were trying to contact the company??? There are hours of reading on this subject on the forum. "Needing to charging batteries" is not applicable here. To be able fully use all components and appliances while parked at home, you want a 4-prong, "50 amp" service installed. As me mentioned this consists of two 120v legs [out of phase], a ground and a neutral. This service is exactly the same as the configuration as the plug a 50 amp electric kitchen range uses. 120 vs 240 is misleading here in that while in fact your new 50 amp service provides 240v capability [two 120v legs] but the vast majority of RVs do not combine the 110v legs to create true 240v circuit. Examples of 240v appliances include: residential kitchen range, hot water heaters, clothes dryers, and whole house ACs/heat pumps....If your electrician is confused by this explanation, find a new electrician!!!!!
PS--if ALL you really what to do is charge your bats--then a "heavy duty 20 amp [120v] circuit is all you need. Make sure the wire you use is large enough to handle the distance of the run--normally that would be 12 ga but 10ga might be needed for a extra long run. Again, you electrician should know how to figure that out.

What's also scary is that the salesman that sold the rig didn't know!!!! What dealer was this?

A classic example of an RV Salesman , who has never owned an RV.
He was selling running shoes at Big 5 last week.
JMHO: First question to ask of a salesman at an RV lot.
" What kind of RV do you have ?"
If the answer is " I don't . " Find someone else, who has an RV to deal with.
I hate to bring this up , Emma Lou, but was there any discussion about , your home state laws about the drivers license requirements , with regard to the coaches weight or air brakes, and you needing special training, and a license change, to drive it?

PS--this topic always brings up a lot of input on this forum. What is really scary to me are some of the post from well-intended RV owners who don't have any professional training on electrical issues. Sorry if I hurt any one's feelings but giving inaccurate advice on this topic could get someone hurt--or worse.....

It isn't different from the modern range receptacle. You want a NEMA 14-50 R, the 3 pole, 4 wire receptacle used for new kitchen ranges. You do not want the older NEMA 10-50R range connector, which does not have a ground connection.
While a 50 amp receptacle makes sense if your RV has a 50 amp service, if your RV is only 30 amps, you could save money by installing a NEMA TT30 R receptacle - smaller wire & only one space in your breaker panel. Still, if there is a chance that you will upgrade to a larger RV in the future & the installation is underground or long, going with the higher amperage service might make sense. You can purchase a box that has 50, 30 & 20 amp receptacles.
IF you install the 30 amp only receptacle, it is important that the electrician understands that this is a 120V receptacle. It looks a lot like a 30 amp dryer 240V connector, and if wired that way it will let the smoke out of your trailer!
