RV Air Conditioners Trip The Breaker While Driving

by James Scott
(UNION POINT, GA)

I HAVE A DAMNON ASTORIA 38 FOOT CLASS A RV! IT HAS 2 ROOF TOP TRANE AIR CONDITIONERS. BOTH UNITS RUN FINE ON SHORE POWER! THE UNITS ALSO RUN FINE ON THE GENERATOR AS LONG AS THE COACH IS PARKED.---MY PROBLEM IS GOING DOWN THE ROAD! THE UNITS WILL TRIP THE CIRCUIT BREAKER AFTER ABOUT 1 HOURS WHILE I'M TRAVELING WITH THE GENERATOR RUNNING! WHAT CAN I CHECK FOR AS I NEED TO RUN AT LEAST ONE ROOF TOP UNIT AS I TRAVEL TO SUPLLEMENT THE CHASSIS AIR CONDITIONER

Robbie Your question is a good one, but there is no way to nail it down with a guess. What you are asking doesn't normally happen and I've never heard of such a thing. An amp draw will be needed on the breaker that is tripping to check the Air Conditioner's performance and the Voltage output on the Generator also checked. I strongly suggest a qualified tech tackle this problem as it could be from many different things.

It Could Be
by: Bud Corwin

Hey James,

As Robbie said, it could be any number of things that is tripping the breaker. One thing that pops into mind is a possible bare wire that is shorting out as you are traveling down the road.

One solution is to put up a curtain right behind the drivers and passengers seat. This would allow you to drive with just the front air on, that is if you don't have some reason to have the roof air on as you travel. It would also be a lot cheaper, saving your use of fuel.

Hope this might help and happy motoring.
