Autoformer

I also have a 50 amp Hughes autoformer and use it on 30 amps frequently

Speaking of Autoformers...what is a ballpark price for one, installed?

Hi usersmanual,

I've come across low voltage on 15, 30 and 50 amp services.

so have I ? so what? I don't get your question?
please explain

Hi usersmanual,

I've come across low voltage on 15, 30 and 50 amp services.

i dont use hookups often, and haven't had 50amp hookup in the past 4yrs

but i have never had low voltage on 50amp, on the occasions i used it

I think your mistaken here; most rv parks have 50amp outlet and a 30amp one. the power supply comes from the same source so if u meter each part of the 50 amp out and the one from the 30 amp they should(will) have the identical voltage supply

you are still only one leg of the 50amp
still only have 30amp service, a solid 30amp,
and you do NOT need to use the autoFormer when using a 30amp rv on a 50amp service
however if its hardwired, just use a 50 male to 30amp female, it won't hurt any thing

Just because you are using 50 amp service for a 30 amp rv does not mean that the full 120 volts are there. I always test both plugs (30 & 50) to see if either has more voltage and rarely find a difference. So if the voltage is low on the 50 amp circuit it would help to have an autoformer.

Yes, either autoformer can be used on either service and supply either RV.

Although due caution using a 30 amp anything between a 50a supply and 50a RV.

Anybody no if you can run a 50 amp power former on a 30 amp service or do you need one for each service

let me give you the easiest answer possible... I do it, about half the summer and 2/3 the winter normally, I do it, ZERO problems.
