rb,

NEC Article 100, Definitions. Branch circuit, multiwire. The definition describes a shared neutral. As far as I know the new Code does not prohibit the use of a shared neutral. In some cases, for branch circuits feeding computer equipment it's better to run two 2-wire circuits instead of one 3-wire circuit.

rb,

Is this for a bedroom?
If so, what you may have heard was in refererence to the new requirements for AFCI breaker protection. If this is the case you would have to locate a special 2 pole AFCI breaker that will work with 3 wire circuits. At the present time the only brand I know of is Cutler Hammer and they may even be difficult to locate.

23/3 -?

Are you sure you are not referring to the rule (408.21) prohibiting a neutral or grounded conductor from "sharing" a terminal lug that is not designed for more than one conductor?

Should the ckts that share a neutral be fed from different legs? This way the neutral would only carry the unbalanced load.
