Joe - circuit breakers (CB's) work on time vs. current basis. A very high amp draw over the breaker rating will trip the breaker very fast. Amp (current) draw just slightly over the rating will take a much longer time for the breaker to trip. Curves are published that show how long it takes to trip vs. the current being pulled through a certain size breaker. Your RV A/C, plus line losses in the wire to the outlet, extension cord, and RV cord put you over the CB rating and also lowered the voltage at the A/C unit which in turn required more current. This is one reason you should always use a quality EMS unit, even at home.
