I finally got my 15 hp phase converter working today using capacitors
and a momentary push button. I plan on using it with a 10 hp 3 phase
air compressor. However just at idle it is pulling 20 amps. I figure
I can use an additional pressure switch to have the converter turn on
before the compressor does. But what do I need to have it turn off
after the compressor cycles off?

Thanks
Steve
