    He STILL should not be using single phase components (dryer outlet) with 3-phase electrical. He should be using 3-phase plugs, wiring, etc.....a 3-phase plug/outlet is $20, why is he messing with a dryer outlet? OP needs help BADLY with electrical expertise, IMHO.

    I def agree with the unrated/underrated jack, but it unclear if he is attempting to run a three phase motor on split-phase, setting up a RPC, or simply using the outlet as a jack from a generator head.

    I took it as the latter when I fiest read it, but now I'm not sure.

    I landed here because I am investigating RPC construction and use, so... I probably shouldnt have said anything anyway.

    The OP hasn't posted anything since starting this thread.

    Ominous...

    I do not disagree.

    But per Code, you can use any plug rated for the usage (volts/amps) which is not used for any other voltage in the "facility". It's legitimate, if not perhaps an ideal solution.

    The 4 pin dryer plug is rated for 250V, and will carry quite a bit of current , so if there are no dryers etc in the facility using the same plug, that's accepted. I won't call it a perfect solution.............

    If it were me, I would prefer to use a 3 phase plug for three phase, and I would at least label each outlet that does not conform to the usual usage with what it provides.

    The misconceptions I've read in this thread regarding the function and use of a neutral conductor versus a safety ground in a single phase circuit are downright dangerous. A neutral is very much a current carrying conductor. Try disconnecting it and see if anything operates. Nuf said.
