My question is not whether this is right or wrong , I may be! This has to do with putting two circuits on a 120 volt 20 amp duplex receptacle.The person would of course break the tab on at least the hot side if not the neutral also. I feel this is a nec violation but I cant seem to find it in the book.

You cannot find it in the NEC because it is not a violation, but rather a relatively common practice.
The NEC will discourage you from trying to use circuits at two different voltages on a single yoke, but the duplex receptacles you see will either be both 120V or both 240V.
If the branch circuit is an MWBC the neutral tab should not be broken. If each circuit has its own neutral from the panel you MUST break the neutral tab too.

I think that is the OPs question and I agree your answer the hard part will be citing a code section.
Pretty much stuck with either calling it a parallel conductor issue or a 're-bonding' of a neutral.

i feel good that its not in the code but hell I got schooled by a millennial , I just even with two two wire circuits you have 208v on a 120 recep., and your this is common it has come up twice in the recent past. Thanks for the insight.

It is not a NEC violation to feed a duplex recpt with one MWBC or two two wire circuits, nor is there a compelling reason not to.

And then there's the Leviton 5842. 120V and 240V on the same yoke.

From the same "voltage system".

Is it just me or does there appear to be a bridge tab on the left side of that receptacle?

It is part of the listing requirement that the hot tab be breakable IIRC.

Yup, and if the 240 L side is fed from the same 120/240 line as the 120 hot and fed from the same MWBC, the bridge tab would be functional and not need removal. Otherwise it could be illegal paralleling, but not necessary a short if left in place.
There better not be a bridge on the neutral side though. :happysad:

Why not? Hook that side to A phase, hook the other side up to B phase and neutral accordingly.

Yeah I brainfarted and was thinking the left side was neutral and hot, not hot/hot.

You just assumed that the receptacle was wrong (right!?) side up in the photo, right?

That about sums it up. :ashamed1:
Any idea why the top of the receptacle has a gold-colored clip on the yoke?

It's a self grounding receptacle aka spec grade.

Finding a 3 pole 20 to this would have thrown me off kilter for a bit. Don't remember encountering one of these before.And then there's the Leviton 5842. 120V and 240V on the same yoke.
