Surge Protector

I have had my rv in a seasonal site for the last year and a half. When we originally parked at the site it, there was only 30 amp service. There was a 30 and a 20 amp plug. The owner had an electrician take the 30 and the 20 to make a 50 amp plug. Up until the last few weeks everything was fine. The surge protector has turned the power to the rv several times. Last night each time the surge protector would cut the power, and it would take only a matter of minutes for it to cut the power off again. We moved to another site today at a newer part of the campground and had no issues. We later moved back to our site, and hooked up again. We have had no issues since. The owner thought it was our rv, and I think it is the surging of electricity going into the rig. Could it be a surge protector getting old and going bad. Thanks.

One think to add. The owner changed the 50 amp breaker before I plugged back in. Haven't had issue since. Fingers crossed.

I'm thinking , that the circuit breaker or the connections to it , were the issue.

After a few heat cycles , wiring connections can work loose.

Would have been very interesting to be looking over the shoulder , of the person replacing that breaker.

Agree with Skip. It sounds as though there is a definite lack of electrical skill involved here, so anything is possible.

The owner had an electrician take the 30 and the 20 to make a 50 amp plug.

A 30A and a 20A cannot be combined to make full 50A service, which has 50A on each of TWO hot wires (100A total). The breaker should not have been changed to 50A - it should have remained as one 30A and one 20A, or at most a twin 30A breaker. Further, I'd be willing to bet that the power feed to your site is a single 10 gauge (30A max) wire that supplied both the 20A & the 30A outlets, so chances are the voltage will sag if you actually utilize the 30+20 total. That could lead to your surge protector dropping out (low voltage protection). It could also lead to burned wires or melted outlet in the pedestal box, but that's the campground's worry.

You may want to open up your ATS and check all of the wires going into it and out of it for tightness and melted wire coverings. OH yeah don't do this with it plugged in or the generator running. You want NO power, not even battery turned on when doing this, Think Safety First.
Also check all of the wires going into and out of your Surge Protector for loose and/or melted wire coverings..

The campground changed the 50 amp breaker and have not had a problem since. I sure didn't think it was anything in my rv. Thanks for the help.
