Hughes Autoformer power booster and surge protector

Thanks Larry. That does make more sense. I guess I was hoping to also offer surge protection for the Autoformer. I can see where your system will work.

I know some surge protectors do not have the "shut off" feature for low voltage drops. Im thinking maybe one of those would work well with the Autoformer. Plug the surge protector in first, then the Autoformer into the surge protector. That way the surge protector would offer some protection for the Autoformer as well as the RV in general. Maybe Im over thinking this!

I have a surge protector and autoformer. The autoformer should be closest to the pedestal followed by the surge protector. The reverse defeats the purpose of the autoformer by cutting off low voltage before the autoformer has a chance to compensate.

Hi,

I probably would be worried about the park low voltage shutting down the surge protector (if it does indeed shut off when input is say 100 volts) while using the autoformer.

The Autoformer output will stay above 110 volts all the time, and will not allow the surge protector to shut off due to low voltage.

I also found that the 30 amp receptacle at one campground was in such bad shape, that the internal brass was not gripping my power cord tightly, and was overheating. When I used my 50 to 30 amp adapter, everything went back to normal, voltage into my RV went up by 13 volts with the air conditioner running.

So if 50 amps is available, I will always plug in there, with the adapter. Then use my transformer if required to keep the voltage above 110 volts.

Fred.

Thanks for the reply. What you just said makes much sense. I never thought of that. My Surge Guard is suppose to shut off at 102-104 volts so that could be a problem. Thanks for enlightening me.

No reason why you can't. I also have a Hughes Autoformer 50amp, but don't have a surge protector. If I recall the surge protector may cut off power if the voltage gets to low, therefore negating the benefit of the Autoformer, which is to boost voltage in low voltage situations.
