Low voltage problems

We had that same issue at a campground we were working at for the summer. We were placed in with the seasonals at the end of the line and didn't even have enough voltage to operate our A/C or refrigerator on a hot weekend day. So frustrating as we also could not leave until the seasonals left and we had empty sites to maneuver around trees to get out. We did have to make use of our generator during the really hot times. The problem was old wiring and the number of sites overtaxing their system. It doesn't help that everyone is adding outdoor refrigerators, portable icemakers, elect rotissiere's etc. And if it goes out, everyone's A/C kicks back on at one time. That was a bad summer!
