I feel like a rookie but I threw a mobile air compressor and generator in the truck that I have. Genny is known good, compressor was newish but not tested. Compressor is 14A FLA, 240V, 1P, genny is 5000W cont/6500peak.
Compressor would start but found that it was pulling 30A, dragging on the genny, and rpm on the motor was 2500 when spec is 3450. Everything tested out good so I knew either the pump had issue or I was not getting enough power to the load.
Irush on the genny was 46A.
I plumbed into to house power and inrush was 76A, cont was 9.6 with no air pressure. SOLID!
So now I know that the genny will not start the load but should handle it. So.... Might I be able to stack some capacitance on the start cap to help this issue? I really think if I can get over the hump, it will work. Just not getting the motor quite up to speed and the start circuit is not kicking out.
