Same here though since Southwire bought TRC the Surge Guard equivlent is a very very close 2nd.. That's what I had.. Biggest difference is the Surge Guard the remote is... Optional.

Also some differences in the installation.

Home was where I park it. but alas the.

My recommendation for 30 amp is the Progressive Industries EMS-HW30C and for 50 amp is the Progressive Industries EMS-HW50C, but I prefer built in. They are also available in plug in varieties that you plug into the pedestal then plug your RV into them. I have been using mine since 2007.

Ours was a PI at that time. We currently have a Hughes Watchdog. Both are good to limit or prevent damage.

And the hard wired models are modular so they can be repaired in place.

My autoformer will take care of 97 volts and run my air conditioner safely.

An autoformer is a totally different discussion. I have both.

Just as a fast note
Autoformers are directly connected across both transformers at one end.
Significance? Zero reduction of transient voltage surges or spikes.
I didn't write the rules I just follow them.

Thanks for the heads up Mex.

I do use a surge suppressor but not an expensive one. It does work as I've had to replace it.

Don,
The following can be of great assistance in learning the difference between auto and isolation transformers.

Down here, its absurd to consider an auto disconnect circuit protector as it means total electrical disconnection more than half the time in rural areas.

Direct distribution lightning protection is the most challenging circuits to create. It means separating incoming power from the load by at least 8 inches of air while offering enticing Corona corona discharge path(s). I know of no lower voltage device that will not burn to a cinder if incoming voltage takes a direct strike.

Does any RV insurance company offer underwriting protection against damage to RV accessories?
