    Mine is 60ft so from main panel to control box outlet is 8awg in the box is 12awg all depends on amp draw and voltage drop.
    There are plenty of calculators online to calculate this.

    Add all your amperage and then use a calculator. if your using 3 750w drives and a 2hp minimum motor i would run the 8awg

    this run will be just for the 3 drives and 3 750w servos

    the vfd is on a separate circuit
