    Hi Jim,
    I have added a link to the article above for the Voltage Drop Calculator to help you with your question about wiring your air compressor. Keep in mind that when connecting an air compressor to a building that is fed from another building that all of the wiring should be considered, which may be a factor for the overall voltage drop.
    I hope this helps,
    Dave

    I’m running a 220volt single phase 15 amp compressor from an out building that’s connected to the garage. How far can you run 10/2 wire with no voltage loss of power due to distance.

    Thanks,
    Jim
