Re: Permissable ???

It appears to me that you would not be allowed to use the same style plug for 2 different voltages. Thus I would have to say you need two different style plugs (thus two different style receptacles), even though it may be the same circuit.

Re: Permissable ???

Not the same circuit.

Article 100

Branch Circuit. The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).

That is what I am saying.

Imagine a range, when you turn on a burner you are only using 240 volt from the outlet.

Shut of the burner and turn on the oven light, now you are only using 120 volt from the outlet.

The outlets rating is 120/250 you are not misusing it.

Same applies to the NEMA L14-30 it is rated for both voltages, that could be at the same time or at different times.

With proper wiring there is no danger of over voltage or under voltage to the connected equipment.

I have done this same basic thing at a factory, all the machines use a NEMA L21-30 plug, all the cord drops use an L21-30 outlet.

Re: Permissable ???

Now I'll have to find where we have to measure our voltages to the grounded conductor. :D

Edit: And just because it's always done doesn't make it compliant.

The word "gullible" in not in the dictionary.

From Microsoft Encarta Dictionary:
gul?li?ble [ g?lləb?l ]


adjective

easily duped: tending to trust and believe people, and therefore easily tricked or deceived


[Early 19th century. Formed from gull2.]


gul?li?bil?i?ty [ g?llə b?llətee ] noun
gul?li?bly [ g?lləblee ] adverb
 
Re: Permissable ???

I still don't believe you.

Although I haven't been successful at finding the "extra" code references to show these voltages are measured against neutral yet. :(

Sam the outlets and plugs we are talking about are rated for both voltages.
 
Re: Permissable ???

Yeah, 406.3(F).

Can you point out what part of

Receptacles connected to circuits that have different voltages ........... shall be of such design that the attachment plugs used on these circuits are not interchangeable.

doesn't have to be applied in this case? :)
 
Re: Permissable ???

Oop, construction is 406.7.

You're gonna have to admit it sooner or later Bob, it's just a matter of time. :D :D
 
Re: Permissable ???

OK,
Hook up all wires at the plug end of the cord.
Only use the ones you need at the load.
Now we are code compliant? Just using more material.
 
Re: Permissable ???

Wow ...
didn't mean to kick off such a discussion ..
I touched base w/ the local inspector .. as he would make the call ..
he cited 406.7 ..
"The use of an L 14-30 is for 125/250 volt usage and not just 125 volt usage." ..
.. still not clear as to whether this is a positive .. asked him to clarify ..
