My best guess without all the loads and the distance to the main panel is 60 amp and #6 copper or #4 aluminum minimum. The total load and voltage drop needs to be taken into consideration. My best guess at full load amps on the rotary phase converter is about 32 amps x 1.25 = 40 amps.

Thanks – Would i be better off purchasing a VFD since it essentially provides a soft start? would i then be able to get by with say a 40 amp breaker?

Yes.

I’d guess you could power that with a 12fla (3hp) vfd. That would run on a 30A circuit.
