Running the A/C with lower Amps
During our last trip, we spent a few days at a friend's house. The friend was nice enough to install a 30A socket for us; however, the socket was on a 20A circuit.
I was able to successfully power the 15k BTU A/C without tripping the breaker, as long as the water heater was running on propane (water heater would trip the 20A breaker). Both my fridge and A/C were running on the 20A circuit.
Am I potentially causing damage to the A/C by running it on a 20A circuit? If the A/C needed more than the 20A, then it would just trip the breaker right?
