We are using the 30 amp power cord that came with the trailer. This is with the water heater not turned on. The microwave not being used. The only other thing we have had running the last two times is the fridge. The 20 amp breaker for the a/c in the trailer by the converter is kicking off.
The 20 amp branch circuit breaker in the RV should not trip as it is a dedicated circuit. Could be low voltage from the campground. Could be a loose wire on the breaker causing heat. Could be a weak breaker and can be purchased at hardware store. Could be a defect with the air conditioner itself or a bad/missing start capacitor.
Unplug and remove the covers so you can see the 120v wires in the breaker panel. Look for heat issues. Replace the breaker if you are inclined.
Check the voltage in the RV is 108+ when running.
Otherwise you might be back to the dealer for warranty work on the air unit itself.
