Question about Dometic Rooftop RV Air Conditioner
I have a ac on my 31 foot park avenue trailer. It was wired with a 10 gauge wire from a braker box which supplied 30 ams of power from the mail plle. The wire I was told was not powerful enough to supply power so i had a electrician run a seperate 6 gauge wire alongside the 10 gauge. Both wires have a seperate 30 amp breaker. The 6 gauge supplies the travel trailer while the 10 gauge wire only supplies the AC unit. It is a 15000 BTU AC. The ac will run for a while fine then all the sudden it will begin to cut out, as if the fan runs at a slower speed. This continues until the breaker kicks. I then rather than running the wire through the invereter to the AC I directely ran it straight to the box . It is however not grounded in the camper. It does have a ground at the main box at the pole. Does this need to be grounded inside the inverter box inside the camper? Or is this acceptable to run it directely to the pole. What I do not understand is that when the AC kicks the breaker it is the one in the camper which is the main breaker. The only other thing that is on is the ref.
Your unit is pulling too much power which is popping the circuit breaker. Either the compressor motor or Fan motor has a problem and you need a pro here. Drawing excessive electrical current is not good and you can do even more damage to your unit by continuing to try and run it!

The problem is not in the wiring, but in the fan motor or compressor...would need to get a meter on the unit to see exactly what the problem is, but it aint the wire...
