    3 phase what? 480v, 240v, or 208v?
    Do you have 3 phase available at the shop? If not the power company will more then likely charge you to run another leg from wherever.
    To run that one wire here for the feedmill 3 miles was 15 grand 20 years ago.

    You'll need a 3 phase panel and breakers. 3 phase is a whole nother ballgame price wise. It aint cheap and you wont find anything 3 phase in the box stores like Lowe's.
    If you need 480v, you'll need 2 panels. 1-277/480v panel, a transformer, and a 120/208 volt panel.

    I would either replace the motors or get phase converters.
    Honestly, to have to pay whats it going to cost to go to 3 phase it wouldnt be worth it unless you converted everything in the shop to 3 phase especially the high demand items like heating and cooling, compressors, etc. Atleast over time it would pay for itself through energy savings.

    Good luck.

    I agree with Mark, from a price standpoint the phase converter would be best, I might know where there is one fairly cheap, I will do some checking just in case you want to go that way.

    Grizzly tools sells them although those things can be pricey depending on the size of the motor.
    Look on the government auction sites and Ebay.

    i've looked at the converters. too pricey...my compressor will be 7.5hp.

    Phil. You'll have to build an entire new service from top to bottom.
    The converter would be cheaper:big_smile:
    You aint seen the price of wire lately? Scrap is selling for 3 dollars a pound.
