Not sure. I think it's 6HP

Thanks but that is an odd size. Generally, common sizes are 5, 7.5, or 10 HP.

The amps correlate approximately to a 10 HP. I will use that for calculations...please give me a few minutes, thank you

An Acme Model T-1-81052 .75 kVA transformer located at the motor fed with either #4 AWG Copper or #3 AWG Aluminium.

Thank you

Are you sure. The specification says secondary is 12V/24V. I need 208V for secondary.

Yes, sure. When used in a boost configuration they act as a multiplier.
