A few years ago we were in the Northeast and experienced low voltage at several CG's. Many of the places up there are older,established parks and on a hot weekend when the parks filled up, voltage would drop to the point that the surgeguard that I had at the time, would shut down. Sometimes moving to a different area of the park would improve it, but more than once, we had to leave the park and go elsewhere. When I got home I saw a Autoformer on Craigslist and have had that hooked up ever since. The way I'm now set up is from the pedestal feed, I have a basic surge protector in front of the autoformer , while the autoformer does have surge protection, it is sacrificial, I'd rather have a cheap unit protect the autoformer, the autoformer then feeds into the PI surge protector which then goes into the xfer switch All units are in the bay and each can be unplugged in a moment should it fail.
