I use an inexpensive (less than $5) tester to check power at the pole before I plug in the rig. It checks for ground faults, reversed polarity, etc. I bought it at Walmart in the electrical section. It has a 110v 3-prong plug that I just use with adapters to plug into 30 or 50 amp receptacles, whichever we are going to use. Twice it has detected ground faults and we moved to a different site. The tester is yellow and has three lights and a diagram showing what each light means. It does not replace a surge protecter. It is only for testing the power before plugging in the rig.
