Generator size for rotary phase converter

A 10KW military generator will easily start a 7.5 HP motor. They are all very conservatively rated. I'm sure you could pull 20KW for a short period of time with no problem. The surge load capacity is at least double the rated load.

Thank you for all your replies!!
Hot wire from the house wont work because trhe shop is not near my house.. BUT the you have given me new hop in the military generator.
