    All dryer cords are #10.

    I would run 500kcmil just to play it safe with voltage drop. M1 cable would be a better choice

    # 10 wire will do. Fyi, I think that #10 wire is orange.

    I've never seen an orange dryer cord.

    Besides, I think the OP forgot all about this thread. I would be nice if he came back to explain what the heck he is asking about.

    Default wire

    #10 wire is WHATEVER color you decide to buy. The Dryer "cord/pigtail" will be red, white, black, and green with a black covering over it.

    Just make sure the receptacle outlet will except the male end of the
    dryer cord.

    So are you going to use a 3-wire or 4-wire dryer cord set.

    Installing a 4-wire dryer cord set can be a little tricky.

    With a 3-wire, grounding of the dryer frame is done thru the
    neutral/grounded conductor of the dryer cord

    With a 4-wire, grounding of the dryer frame is done thru the ground
    conductor of the dryer cord.


    And if not sure how to do this properly, post back, there some good
    guy here, that will walk you thru it.
