    It depends on the equipment. Either #6cu or #4cu, but most likely #4.

    #6 may likely work(don't know what equipment), No matter what, 4 would decrease voltage drop, and like Stan says #6 is likely code and acceptable.
    Whenever you are undecided, larger is better, you can adjust breaker size.
    The price difference of the wire is minimal compared to the labor involved.
