Re: Split Wired Duplex Receptacle
Al, a duplex receptacle is two receptacles on a single yoke. If you break off the link, then each receptacle will only get 120 volts. Bottom line, you use a standard 125 volt duplex receptacle for multi-wire branch circuits.

Re: Split Wired Duplex Receptacle
what you would need for a split wired receptacle would be a 2 pole breaker, however.
according to NEC 2002 210.7 (C)

The NEC does not require the use of a two pole breaker for this application. It only requires a means to simultaneously disconnect the ungrounded conductors. Approved handle ties on single pole breakers meet this requirement.

Re: Split Wired Duplex Receptacle
Require a two pole breaker in place of handle ties for a multi wire circuit on one yoke?
Why?
Will what?
Require a two pole breaker in place of handle ties for a multi wire circuit on one yoke?
Why?

Re: Split Wired Duplex Receptacle
I don't have my copy of the 2005 NEC with me but the terminology needs to be clarified.
Single pole circuit breakers with approved handle ties are acceptable for some uses including service equipment. The handle ties are for common switching only.
A standard two pole circuit breaker is two single pole circuit breakers that are built as a single unit but the handle tie can be removed and the circuit breaker may be used as two independent single pole circuit breakers.
A two pole common trip circuit breaker is built together the same as the previous two pole circuit breaker except the two single pole circuit breakers have an internal trip mechanism that will trip the other pole if the first pole trips.
The same holds true for three pole devices.
If memory serves me correctly, multi-wire branch-circuits will require a common trip device since the language has been changed to indicate that all of the phases must be opened simultaneously.

Re: Split Wired Duplex Receptacle
Charlie,
For the rules in 210.4(B) and 210.7(C), common trip is not required. The requirement is to simultaneously disconnect the ungrounded conductors, not simultaneously trip the common conductors. The rule is for protection of someone working on the common yoke so that device is completely de-energized. There is no reason to have a common trip for this application. That would be permitted, but not required by the code.

jap2525,
That does not meet the code rule. The means to simultaneously disconnect the ungrounded conductors must be provided at the branch circuit panel.

Re: Split Wired Duplex Receptacle
I was just having a little fun with that one,but,I don't see how you can tye the handles of two breakers together for disconnecting means simotaneously and not see that as a common trip?If the tye is rigid enough to disconnect both breakers at the same time then if one tripped the other should trip be brought with it.Also where does it say that the circuits to a split receptacle have to be one above the other? couldn't a receptacle be fed from circuit #1 and cir #42? what kind of handle tye would you use then? I know common sense would say put them one above the other so you could tye the handles together,but if the tye is flemsy enough to let one of the breakers trip and the other to stay energized then I feel the tye is not upholding it's worth for a simotaneous disconnect.
