I put in a circuit for a couple of sump pumps today. The nameplate rating on each of the sump pumps was approx. 9.5 amps. (I know it was 9.something.) I put both on a single 20A circuit. I am probably overthinking this, but I am wondering what the chance is of both of them starting at the same time and tripping the circuit breaker. I really don't know how much current these motors will actually draw at start up.. Hmmm... any thoughts?
