Question about Dometic Rooftop RV Air Conditioner
On a warm to hot day my air starts to trip the breaker, we have checked the load on the breaker, if you let it sit for alittle bit and turn it back on the line amperage runs about 17-18 amps then gradually works up to around 22-23 amps before tripping. any help would greatly be appreciated
I suspect that your unit requires a 30 amp circuit. If it is running at 17, motor loads require 125% which is 21.25 amps. Conituous duty (means that the unit runs for 3 hrs or more) also requires 125%
You should be using a 30 amp circuit.

Compressor is working hard, and is probably caused by dust & or dirt in evaporator coils & fins, provided your incoming voltage is high enough to begin with. You should have no less than 115-120 volts to start. Remember, low supply voltage, causes higher amperage draw. One common problem if your in a park & at the end or near end of a power run, once everyone else does the same, your incoming voltage could be low to start with. 17-18 amps when leveled off and running is pretty high. Start-up, maybe, but not once up & running. Are you plugged in directly to pole or power source or is there another extension cord there?
