When I run the front air conditioner along with either the electric water heater or the refrigerator on electricity, one of the two coupled 50Amp main breakers pops. I am wondering if this is a common problem with the 2000 Alpines or if I just have a breaker that needs replacing.

This occurs if I am plugged into shore power or running off the generator. When it is hot I must switch the water heater and refrigerator to operate off gas to keep the air running in the front.

I had a 2000 40Ft same color as yours, wish I had kept it. I would get a amp probe and see at what amps breaker is tripping. The breaker is most likley weak and needs changing. I could run all and never tripped. Also check to see if all wiring is tight, from power cord and generator.

With 50 amp service, which is really 100 amp service, you should be able to run just about everything at once.

At noted above, an amp probe will determine the actual amperage draw of each item.

The coach could also be miswired so that the loads are not balanced between the two legs and one leg is drawing more than 50 amps.

If the amp probe shows correct amperage, then the breaker would be suspect.

Please do a search on generator wiring and also electrical issues. My guess, is the incoming service has loose connections, and the generator wiring has worked loose. You might not have had problems before, but things get loose on the coaches.

This morning I took the breaker panel cover off to check the 50a main breaker connection and guess what I found? The red cable coming from the transfer switch to the main breaker wasn't tight. Without much force I was able to pull the cable out of the breaker connection. Tonight I'll fire up the generator and test the breaker using an amp probe.
