Autoformer

Plug in the autoformer to boost the voltage. Then plug in the surge protector. It will shut off the RV at a low voltage, so if that was plugged into 105 volts, it would be cutting off the power when it really does not need to - because you have the autoformer.

Good luck!

I have wondered about getting a cheapie surge protector between the pedestal and the autoformer just for something to eat a spike or surge, but doesn't bother with low voltage shutoff.

Cheapy surge protectors have a tiny MOV. They react so slowly the transient voltage spike already passed right on through. I'm getting ready to order some bi-directional TVS transient voltage suppressors. Maybe I'll write up a little ditty. Lots of MOVS connected phases to neutral neutral to ground and TVS wired in parallel do something for a living beside lighten the wallet.

This is how mine is set up....Dennis

Some autoformers have built in spike and surge protection. I don't know how effective they are, but I see no need to add a surge protector ahead of the autoformer. Adding a surge protector after an autoformer that has protection may not help much. I have read that you should not stack surge protectors in this manner.

Though mine (When I use the surge protector) is temporarly the other way around..... Let me join the chorus of the above singers.

Future plans includ installing the portable Surge Guard unit (This is easier than it sounds) AFTER the already installed Autoformer.

Spike protection yes
Surge.. I have never seen one with Surge protection.. Just Spike.

That said there is ONE autoformr that can buck overvoltage (Surges) as well as boost under voltage (Brownout) I can never remember the brand..But a surge protector AFTER it is still a good idea since on both BOOST and BUCK..It has limits and I have seen campgrounds that test those limits.

Thanks for the help!
