    On a 120v three prong power cord, which is the common side? is it the
    "ribbed" side or the other side?

    thank you

    the "ribbed" sides of cords are pretty much always the negative

    You should never try using the power cord itself to determine polarity.

    If you look at the plug end you will see a round ground tang and two
    other flat tangs.
    The NARROW tang should be the hot or live ckt.and the WIDER tang should
    be the neutral ckt.
    You can also purchase a tester to check the AC receptacle polarity at a
    hardware store for a couple of dollars. HTH

    How about circuits, of course for professional semantics experts it may
    violate political correctness.
