I normally don't do off-topic posts but I have been to my electrical wholesaler
and didn't get much help and I know there are a couple of guys here who know
I want to buy some receptacles for 3-phase wall outlets. What they sold me was
20A, 3PH Y 120/208VAC
4P 4W Not Grdg. Non-NEMA
The receptacle has a tag which says:
CAUTION:This device is not for grounding use.Connect only to non-grounding
I'm ready to return this stuff but I don't know what to ask for!
I have a 30 amp (10 gauge wire-red/black/white w/ground) 3-phase 208 V. wall
outlet that needs a receptacle. Also a 20 amp wall outlet.
Can someone tell me the technical terms/names for these devices? And their
As an aside what do X, Y, Z, W stand for? X, Y, and Z seem obvious but what
about W. (It's screw is silver, not green.) How about 4P and 4W?
Thanks for technical assistance.
