OP here. So we were camped this past weekend at a FHU Site with 50 amp. I plugged in my 50 amp Surge Guard to see if it still I had issue with my main AC. After getting power on, flipped on the main 15k BTU AC and started and ran fine. Turned on the 13.5 BTU AC and started and ran fine. Now, it was not hot so I did not need to run both AC's but I did not experience any electrical issues all weekend.
So, what could have been the problem over Labor Day where, even after the CG replaced the 50 amp breaker I still could not run my 15k BTU AC unless I unplugged the surge protector and plugged my cord directly into their pedestal? Could that CG have another issue that my surge guard was protecting me from. I did not have any problems that weekend even though I was plugged in direct with no surge guard. tks
