  • Wiring for 304 XMT

    I just bought 304 XMT (230/460v) with feeder and now I need to install a dedicated wiring system for the machine, in garage. Can someone tell/show me what wiring system should look like? Or share a good wiring instruction on here?


    The plan is to wire it myself and then have a certified electrician inspect it to make sure everything's safe. I'm taking my time to make sure I understand what I'm working with.

    For phase 1 and phase 3, from what I understand, typical home use 1 phase, so I'm going with that.

    Here's what I get from the Miller's Manual:

    60 Hz Single Phase #1
    Input Voltage: 230
    Input Amperes At Rated Output: 53
    Max Recommendation Standard Fuse Rating in Amperes Time-Delay: 60
    Max Recommendation Standard Fuse Rating in Amperes Normal Operating: 80
    Min Input Conductor Size in AWK/Kcmil: 8
    Max Recommended Input Conductor Length In Feet (Meters): 85 (26)
    Min Grounding Conductor Size in AWG/Kcmil: 8

    60 Hz Single Phase #2
    Input Voltage: 460
    Input Amperes At Rated Output: 27
    Max Recommendation Standard Fuse Rating in Amperes Time-Delay: 30
    Max Recommendation Standard Fuse Rating in Amperes Normal Operating: 40
    Min Input Conductor Size in AWK/Kcmil: 10
    Max Recommended Input Conductor Length In Feet (Meters): 224 (68)
    Min Grounding Conductor Size in AWG/Kcmil: 10


    MATERIALS
    Time-Delay RK5 fuses rated for 30 or 60amp?
    A roll of 8/2 or 10/2 wire?
    6-50R receptacle
    Line disconnect device/box
    Metal junction box for the receptacle
    Metal conduit (flexible or rod?)


    Other suggestions are welcome.


    Thanks

    don't look at #2 that is for 460v and you won't find that in yer geerage.


    60amp Circuit Breaker
    #8 wire
    6-50r (receptacle)

    You'll also need a 6-50p (Plug) for the end of the XMT power cord.

        You may not need additional disconnect.

          8/2 or 8/3 wire?

            Need two hots and a ground. If you are making an extension cord use SO cable, if you are making a run through conduit use THHN, if it is all in a wall/attic you can use range cable.

              When discussing WIRE- the run from the panel to the receptacle either in conduit or through the wall the Ground is not counted in the numbering.
              8/2 is actually 3 wires
              8/3 will be 4 wires.

              You only need 8/2

              CORD- all wires in the cord are counted
              8/2 will only have 2 wires.
              8/3 will have 3 wires.

              Cord is used for power cords on machines and extension cords.
