Main breaker trips with A/C and Microwave on.->RESOLVED
My main circuit breaker trips if we start the microwave when the A/C is running. Today when it happened, I forgot to turn off the AC before resetting the breaker and the A/C wouldn't start. I turned it off at the thermostat, set the breaker, and turned on the A/C and it ran.
Rig is a 2000 Coachmen Class C 30 amp system with a Dometic rooftop A/C unit.
This started last summer so I replaced the main breaker:
T&B
Type TB 120/240 VAC
Cu/Al HACR Type UL
1 POLE SR-100
E162469
LR102619
A/C works fine by itself and the thermostat is set to Auto and Lo.
Do I have a capacitor or something going bad?
I'm pretty handy but don't know what to look for or where. Can I be low on Freon or whatever they use now?
Thanks!

The issue was originally caused by a 14-year-old breaker getting weak. It was accidently replaced with a 20AMP breaker instead of a 30AMP. This replacement breaker continued to trip because it was below the required capacity to handle the load and was working as designed. A 30AMP replacement is on order.
