Is it a violation to install a nema 14-50R and only terminate the hot conductors. The circuit does not require a neutral.

How about 110.3(B). It was designed to be installed as 120/240 receptacle and installed with a ungrounded conductor.

You could be creating a potentially dangerous situation, if in the future a different piece of equipment is plugged in.

Why can't you install the correct receptacle?

Not a direct violation, but a 110.3(B) violation if manufacturer's instructions do not include such a connection (which is quite likely).

CA 50 instead?

CA 50 instead?

Short answer from me is I don't know. Can't think of why you'd have to install a neutral if you're not running a mwbc. Now, to avoid the issue entirely, have you looked at using a California 50 instead?

Check out a CS8265C by Hubbell.

If you have another 14-50 R on the premises with the grounded conductor present, I'd say you might be in violation of 406.3(D)

Ignore my suggestion of the CA50. The CA 50 has a neutral, too. The Hubble diagram I looked at showed 'G' for the third prong, it grounds on the shell. Sorry.

Along with 110.3(B), I'd call it on 406.3(A).

"... Grounding-type receptacles shall be installed only on circuits of the voltage class and current for which they are rated, except ..."

A NEMA 14-50 is rated for a 120/240 volt circuit, not a straight 240 volt circuit.

Fine to connect the male 14-50 to a 3 wire cord with no neutral, but bad practice on the female device.

This is for a peice of equipment not sure what it is located in a lab.
The first question is what type of plug is furnished with the equipment under consideration.

If unknown, the appropriate receptacle configuration would be a 6-50R (assuming a 208V or 240V circuit).

First hit on google for "hubbell 6-50r": "http://www.buypowergear.com/detail.aspx?ID=4168" or even the 5th hit: "http://www.plumbersurplus.com/Prod/Hubbell-HBL9367-Receptacle/85764/Cat/1338?utm_medium=referral&utm_source=googlebase&cvsfa=63&cvsfe=2&cvsfhu=3835373634" (Plumbers Surplus????)

Now try to find an L6-50R...
