Front AC tripping breaker

[marandjwr]

our front AC will run for 15-20 minutes then trip the breaker because it's hot... surge protector reads that it is only pulling 15 amps just like the back... what's your guess? weak breaker? or something more serious I should be looking into?... it's a 20 amp breaker

You may have an issue with a bad circuit breaker. I would recommend that you re-wire (interchange) the front and rear A/C circuit breakers. Then run the A/C's to see if the rear A/C now trips the circuit breaker. If so, you know that you have a bad circuit breaker.

Also, if you try the test that I previously posted, check the wire connections to to the circuit breakers prior to interchanging the wiring to the circuit breakers. There is always the possibility that the connections may be loose and causing heating at the terminals. This could also cause the circuit breaker to trip prematurely.

Hope these suggestions help.

I would agree with Guy's second post. Had a breaker tripping on the Dry circuit in our old Mobile Home, turned out to be loose terms in the breaker box heating up and causing the breaker to trip.
