220v?

[cookeville34]

Hey is it advisable to install a 220V oven in our 79 Sovereign? (We are not using any gas appliances). We had already decided on a 110V cooktop and hadn't planned on installing an oven.

I could easily install a larger electric box, and the original wiring appears to be #10 gauge. Or is it possible to convert 220v to 110v?

220 volts to 110 volts, yes. As far as wire guage, I'll wait for the electrical types to respond.

I believe if you are going to do this you should keep it "legal" for RV use, and not put in some downrated system.

That means going up to 50amp service.

You need to run new wire, but you would need to at least add wire for smaller service. If you go to 50a "RV" service, you can plug into 50a-240V service at most larger campgrounds without worrying about adapter plugs and funny looks.

Make sure the oven draws less than half of the 50 amps. I seem to remember 50 amp service being split into a 30 amp pole and a 20 amp pole.

I think that may have been an earlier configuration that airstream used to try to tweak more power, before 240V 50A service became available.

What I'm recommending is full bore 50A service at 240V. You can't run a 240V service off of a 30A 120V service and a 20A outlet.

I would not advise it but it can be done.
You will need to be careful on how you wire it into your breaker box, in fact you may need a new breaker box. The “neutral” wire going to the CG pedestal will have to be the same gage as the 220 hot wires since you will have an unbalanced load.

You will only be able to use the oven in CG with the 50 amp service as CG 30 amp service is 120 only. Most state & federal parks are 120/30 amp only.

You will also need a pigtail adapter from 50 to 30 when camping in CG with only 30 amp service.

In a 30 amp CG you will "not" be able to run your AC & counter top stove at the same time.

Probably something else I didn’t think about but that is my quick version.

I may not have been clear, but the 240 volt service was split into two "halves", one side was 30 amp 120 volt, the other was 20 amp 120 volt.

Someone noted that it was possible to convert 220v to 110v, that appeals to me. How would you go about that?

[markdoane]

There are two ways.

1. If you have 240V service, you have two hot legs and a neutral. The voltage between the hot legs is 240V. The voltage between either of the hot legs and the neutral wire is 120V.

2. You can use a transformer.

Way #1 in the post above is the way it is done in your house.

I was wondering more if it was possible to convert a 220V appliance like an oven, to 110V?

I doubt it, but why not go with a convection/microwave oven which is 110V?

Way #2 is the only way I know off. Be prepared to use big wires, the transformer would weight +100 lbs.

[cookeville34]

Ok, it was just a thought anyway. I think I'll stick with the 110v cooktop and a microwave. I definately don't want to add 100# of weight.

Hi there;
As, in FRANCE, we use 240v / 50hz, I'have equipped the trailer with 3 transformers, to keep all genuine appliances:
One for the A/C (the biggest ), one for the fridge and finally one for the Univolt ( that passed this year....). the frequency is not a problem to run allright;
