Air Compressor help
As for power...
For several years I ran mine off of a 125' pre-made #10 metallic flex cable run purchased at Lowes.
Just use the white for the second leg of the 220.
#10 is rated for 30 amps even at 125'
If your motor draws less at startup, #12 is rated for 20 amps.
A 220 motor is more efficient than a 110
