So, I'm having this exact issue, let me explain. Camping last year plugging into the RV resorts 50 amp. Now we "always" use our portable progressive surge protector at the post. It clicks on after the 2 min cycle sending power to the MH transfer switch and on to the hard wired surge protector. Now the power was coming in high at the surge protector at the post around 128 - 130. The Progressive at the post wouldn't trip but the hard wired one did over and over. It stated line 1 was 131 power removed. For some reason it reads higher voltage than what the post progressive reads.
After a while it stayed on but the meter we had plugged into a outlet was reading high around 129. So needless to say I'm heading to Fleetwood in Indiana in two weeks to verify we don't have eletrical problems. I wish it had a bypass I could have used it. Maybe if there's no problems I'll just have it disconnected and use the portable post only.
I'm not a electrician, but is there any reason voltage would increase after the portable post surge protector that would trip the hard wired surge protector?
