Hi Vicr, help me be safe. I was at a state park with 30 amps hookup and had 15k BTU AC running and my wife turn on coffee maker and breaker in trailer trip. I was at home plugged into 15 amps house outlet using adapter and my AC running and I ran vacuum in camper and trip power strip that camper was plugged into. I was at last campground plugged into 30 amps and AC running and electric water heater and wife turn on coffee maker and trip breaker at campsite plug. Breaker in camper didn't trip that time. Using adapter, I plugged into 50 amps and never had a problem tripping breaker with AC, water heater and coffee maker running. Should I not plugged into 50 amps?
