    More proof you can't argue with an idiot that thinks they know everything.

    They call me stoopid.

    Q. Is it permissible to wrap a stranded wire around the screw terminal of a
    receptacle?


    A. According to the UL White Book under the RTRT category, stranded wire is
    permitted to terminate to a screw terminal of a receptacle [110.3(B)].

    For 18, 16, 14, 12, and even 10 AWG - Hell yes. We do it all the time in
    the field. Terminals cost about 65 cents each. That is $650 a thousand.
    Then you need a $190 calibrated tool to crimp them. Now are you going to
    wrap the wire around the screw or screw yourself?
    Oh yes, you asked permission - Many contractors would send you down the
    road kicking beer cans if you insisted on using terminals because some tech
    writer put it in the UL white book. I actually know of a case where an
    electrician was fired for using terminals!

    I think this counts as a yes vote as well.

    The one caveat I would interject...

    If the instructions that come with your receptacle specifically state to use
    'solid' conductor's only, then no. The manufacturer's instructions should
    *always* be followed. UL assumes that such instructions will be followed in
    installation.

    But if there are no prohibitions from the manufacturer, NEC states it is
    allowed. And of course, if the manufacturer's installation instructions
    specifically allow stranded wire, then of course the answer is 'yes'.

    P.S. It is also important to note the wire materials allowed by the
    installation instructions. Some receptacles are for Cu only, others Al-Cu.

    So this vote is a sometimes. :)

    For heavens sake, read again what I wrote. I said 'if the instructions ...
    specifically state to use solid conductor *only*, then no.' I further state
    that you should *always* follow manufacturer's instructions.

    Are you saying that 'if the listing specifically says the screw binding
    terminals is suitable for stranded wire' you should *not* follow them? Who
    died and made you king of the world? UL testing of equipment assumes it is
    installed IAW manufacturer's instructions. If they say to use stranded wire
    and you *don't* then you're wrong. If the instructions say either stranded
    or solid is acceptable, then that's the truth, not some warped idea that you
    have.

    Okay, *that* makes sense. Sorry I was a little 'short' with you, but I
    misunderstood what you were trying to say.
    purpose.

    Agreed!!!
