    Please help. 3 phase hookup to bridgeport?

    I've got a bridgeport clone that needs to be fixed urgently here at work. Basically, the original cord got ripped out.

    So, I have a new cord and installed the 3ph plug onto this new cord. Now hooking up the wires to the actual terminals concerns me.

    I have 3 phases:
    xyz, and ground of course.

    Well on the actual mill, where there's the terminal, I have a "1, 2, 3, g"

    So does "x" correlate to "1", etc.?

    Does the order of which I hook up the wires actually make a difference? As long as ground is ground. I know for another machine I wired up here, it made no difference as long as the ground wire was on the ground terminal.
    Thankyou!

    As long as you hook up the ground properly, it should run. You will have a 50-50 chance of it running the correct direction. If it runs backwards, just swap any two wires (that is any of the power leads NOT GROUND) to reverse direction.

    x to 1
    y to 2
    z to 3
    ground to ground

    If this runs backwards, try;
    x to 2
    y to 1
    z to 3
    ground to ground

    all of this assumes the motor ran in this location before and the voltage is correct.

    So really, the worst that can happen is that the motor will run reverse? Alright, sounds good. This mill was running in this same location just fine 2 hours ago. Thanks for your quick reply.
