The Steveco 90-66 is the one most folks have had the greatest success with.
G.E. potential relays are rated 3 HP.
Steveco potential relays are rated 5 HP.
You will have to use an auxiliary contactor to start your converter, because
your idler rating exceeds the potential relay rating. Select a contactor rated
at least 7.5 HP at 240 volts, assuming a 240 volt converter, of course.
Figure on about 900 microfarads for your start capacitor, also assuming a 240
volt converter.
Figure on about 90 microfarads for your A-B capacitor (across which would be
connected the 900 microfarad start capacitor, switched by the auxiliary
contactor).
Figure on about 60 microfarads for your C-B capacitor, thereby giving you the
nearly ideal 60/40 percent balance (actually, an intentional imbalance).
Figure on about 30 microfarads for your A-C power factor correcting capacitor.

Hi Peter,

Would there be a wiring diagram to accompany the details above?

Have a good day,

Jim
