On starting the microwave my circuit breaker pops in my Star Stream trailer. Trailer is plugged in to a dedicated 20 amp house circuit and no other AC applicance is running in the trailer. I'm being told that I really need to have it on a 30 amp circuit, but I'm having a hard time buying the argument because the microwave in my house is on a 20 amp circuit, and the circuit breaker for the microwave in the trailer is labelled 15 amps. ???? The microwave is still covered by warranty, but it's just the hassle of getting hooked up to my pickup and towing the trailer 40 miles at 10 miles to the gallon that bugs me. I would like to just take the microwave out and take it in to the dealer for replacement.
