Sounds like you want 2 HP or less. Be sure to change the
oil, and put in good quality oil. Lubrication will help keep
the amperage down. And oil the bearings on the motor, too,
with ND-20 or equivilant. Keep the friction down, and that
will help keep the amperage down.


Thanks for that advice.
Pretty much settled on this.
Should be all I'll need.

I think Clare had the best idea about changing your single 115 line to a
220-240 line. Although I don't know if that calls for a third wire or
if you can use the ground as a neutral and drive a ground rod in at the
garage. If possible, that is your best bet for now and down the road.
Double your capacity through the same wires.
IF the circuit is dedicated to the compressor you can get away with
L1 and L2 and ground with no neutral as you do not need any 110 volt
capability. No ground rod issues ar anything, assuming you have a
grounded cable now. You do need to mark the white wire red, or pigtail
a red wire to it to identify the former neutral wire as a live
conductor.
