I turn off pedestal breaker, plug in surge guard, check for proper lights, turn off pedestal breaker and plug in camper, then turn on pedestal breaker. I do this before I unhook for the reason already given in this thread. If I have to move I don't have to hook up.
Last year I had to move sites once based upon a floating netural in the pedestal. I found it with this method so no harm done to my rig.
