ECN Forum Forums General Topics of the Trade General Discussion Area Kohler Generator 120V, 7.5KW

Just about any ATS should have NCHO generator start contacts. Whether or not you can use a higher voltage or multiple pole unit depends on being able to set the normal and emergency voltage sensing for 120 single phase. The emergency side sensing should also check that the frequency is within acceptable limits before switching. I almost forgot to mention that the coil that is pulsed to actually perform the transfer would probably need to be changed. It is extremely easy to smoke the coil with its low duty cycle. If it doesn't fire across and open the contact on the other side, that coil won't get a second chance.
