My coach has 50 amp service. I have a 50 amp surge guard installed. While plugging into shore power, I noticed that there was a 60amp circuit breaker installed for the 50 amp plug-in. My question is, will the 60amp breaker be a problem. I have been plugged in to this breaker for about 2 weeks, today my surge guard shut down power to the coach and the over/under voltage indicator was flashing. I checked the shore power breaker and it had not tripped. I reset the breaker and the surge guard did its verification and allowed power back to the coach. Thanks in advance for all of you electrical guru's out there for your help.

The 60 amp breaker should be no problem at all(there probably are two 60a breakers, one on each leg of the connection). It would only come into play if you used more than 50 (or 60) amp on one leg of your connection. Sounds like your SurgeGuard did what you bought it to do, an protected you from a voltage problem!!

I run a digital line meter inside my coach in conjunction with my Surge Guard, so normally know if the park voltage is a bit lower or higher than desired, so have some idea of what the problem is when the SurgeGuard disconnects power. Another way to verify over/under voltage would be to check the power power with a multi-meter. Most of the time there is a problem it is low voltage. But the park we are in now tends to have high-voltage problems.

Your coach should have 50 amp breakers, preventing you from drawing over 50 amps.

50A breakers would be slightly better, but chances are anything that would trip a 50 would also trip a 60.

And your coach has a 50A breaker of its own in the onboard load center, so the only thing the shore side breaker is protecting against is a potential short in the shore cable itself or the receptacle it plugs into.

I wouldn't bother to change it.

The 60 amp breaker on the power pole is there to protect the campgrounds feed to the power pole and not your RV. Your coaches main breaker and surge guard are what protects your equipment between your coaches main breaker and the power post.
