    If I have a 10 hp, 230 vac, 3ph motor with a current draw of 24 amps.
    I would fuse it with a 30 amp time delay.

    OK now my question. Do I wire it with the capability of handling 24
    amps or 30 amps?

    Thanks for the help.

    you calculate 25% over the Max expected current.
    24 * 1.25 = 30 amps

    Is the minimum to start with, then you have length of
    wire to consider.
