I need help
First of all, I have a 50 amp fifth wheel and so obviously I have had a 50 amp power supply for several years. I also have a 50 amp surge protector/Electrical Management Systemm(EMS), which is used between the power supply and the trailer. This weekend after coming home from an outing, I hooked everything up and the surge protector/EMS showed an open ground and thus would not allow any power to be put in the trailer.
I borrowed another surge protector/EMS from a friend and found the same thing occurred, that is, no power and an open ground. I disconnected the surge protector and plugged the trailer's 50 amp cord into the 50 amp power supply and voila everything worked. I used a circuit tester in three different locations in the trailer and the indicator was that everything was wired correctly.
Any suggestions, could it be that one of the legs of the power picks up one of the "open ground" or what should I do?
