New Trailer with 50 amp service?

Short answer. Yes

Ken

Yes, just be careful about using electric water heater, and microwave at the same time as the 1 AC.

Hi,

I'd recommend getting an Ems if you don't already.

I tend to monitor my voltage constantly using a Kill-a-Watt meter.

Yes and all of the above.

I'm looking at the HUGHES Autotransformer. It looks like I'll now need two adapters to use it.

“I think I can just use an adapter and ...”

Some basic RV electric reading should be in your immediate future. And dry camping is easy, fun....

Huges Autoformer just raises Line Voltage...not amps available
30A is 30A

50A RV on 30A (50A provides 6000W/per leg---12,000W and 30A is 3600W Total)
Place water heater on propane
1 A/C unit (shut down if wanting to use Microwave)

A autoformer can come in handy if you run into a low voltage problem but it can not do what a EMS can. Get a progressive industries EMS. I prefer hardwired.

Progressive Industries EMS is a very good protection system. I have the portable unit and no issues.

You will need to get a 30 amp to 50 amp adapter as well.

The other comments about not running 2nd air and microwave are all valid. Just watch what things you are powering on.

I just spent the 4th of July at a 30 amp campsite and my 5th wheel is 50 amp. We had no electrical issues at all.

Hi,

I don't understand why you would need two adapters for the Hughes.

I use an autoformer partly because my RV is 30 amp. I always check polarity and voltage under load before I plug in my unit.

I do have an inverter/charger that does load support--but that doesn't mean it does voltage support.

There are autoformers from Mexico that can support 50 amp. I have the Sola Basic (4000 VA) which both boosts and bucks voltage.

The Hughes folks do have a 50 amp autoformer, which supports both legs of a 50 amp RV. To use it with 30 amp shore power, a 30 amp to 50 amp dogbone adapter would be needed. This would be a good item to own.

The reason for having an ems, on 50 amp, is the risk of having an open neutral. That can present up to 240 volts on one leg, causing damaged to most of the 120 volt devices on that leg. The EMS would disconnect, or prevent current flowing when plugging in.

Or, alternately it would be quite possible to have 140 volts on one leg, and just 100 volts on the other. If an air conditioner were run on the 100 volt leg, it may be permanently damaged, what's even worse, is, the damage can 'sneak up' on you, as the damage is cumulative.

Get a top of the line EMS from Progressive Industries.

There is much lower risk with a 30 amp RV and I have superior surge repression on the RV. I do most often run with the Sola Basic autoformer as low voltage damages a lot more RV's than high voltage.
