Surge Guard w/ ? Power pedestal - how do you handle this?

I always check the power pedestal BEFORE plugging my rig in - period. That said, I also trust the Surge Guard protection more so than most of the people I've seen that work on the pedestals in campground. I had to teach one of the techies in a Washington campground. Before hooking up, I notified them the pedestal was hooked up wrong. He questioned it and I showed him on my meters where it was wired wrong. He pulled the cover and sure enough, the wiring was not correct. Trust your surge protector....Dennis
