a 30 amp curcuit is good for a sump pump.

From what I can gather, this is a 220V single-phase pump, rated at 1.5hp. The pump will need to be accommodated as an inductive load(partially), assuming a power factor of 80%. This translates to an approximate range of load between 1500 and 1700 watts per the power rating. Using this basis, the generator used should be capable of supplying 2.5kVA for the pump operation alone. This translates to about 2000 usable watts, which is above the capacity of the pump by a fair enough margin to keep either motor or source from suffering any damage. These figures may need to be checked against current code; and, the estimations used may be revised. These computations are based on an average available from the generator, and NOT the maximum ratings. If maximum ratings are used, computations from the Vrms and Irms need to be applied with a factor of 0.707 for each between maximums and rms values.
