Lots of people are relying on a auto former to protect them. The problem is they only improve voltage by about 10% and they don't shut off if the voltage gets to low. I would recommend you get a Southwire Surge Guard and put it after the auto former. My Surge Guard saved me at least 3 times last year from bad power in campgrounds. The nice thing about the Southwire Surge Guard is it will turn on automatically if the power improves.
