do nec require the neutral conductor to be identify in the panel with the ungrond conductor i know it does with mulitybranch but what about 120v circuit with its own netural do i still have to have the identify ?

No you don't have to if you have two wire circuits.

But a good idea if you have more than one 120V-2 wire circuits installed in a conduit. But not required per NEC. At least I don't think so.

I think it is required if you have 2 circuits each with their own neutral in one conduit. The purpose of this requirement is to allow us to know what neutral belongs to what circuit

Here is what the 2014 states

(B) Multiple Circuits. Where more than one neutral conductor
associated with different circuits is in an enclosure,
grounded circuit conductors of each circuit shall be identified
or grouped to correspond with the ungrounded circuit
conductor(s) by wire markers, cable ties, or similar means
in at least one location within the enclosure.


Exception No. 1: The requirement for grouping or identifying
shall not apply if the branch-circuit or feeder conductors
enter from a cable or a raceway unique to the circuit
that makes the grouping obvious.


Exception No. 2: The requirement for grouping or identifying
shall not apply where branch-circuit conductors pass
though a box or conduit body without a loop as described
in 314.16(B)(1) or without a splice or termination.

Sorry I get off with the 2014-- The 2011 states this

210.4(D) Grouping. The ungrounded and grounded circuit conductors
of each multiwire branch circuit shall be grouped
by cable ties or similar means in at least one location within
the panelboard or other point of origination.
Exception: The requirement for grouping shall not apply if
the circuit enters from a cable or raceway unique to the
circuit that makes the grouping obvious.

I agree with Old Man Moderator, required if there are multiple circuits in a raceway.

Is this a change for the 2014?

210.4(D) talks about MWBC not multiple two wire circuits. The OP agrees that neutrals of MWBC needs grouping.

Yes that is a change for 2014. I posted the 2011 because I realized that that was what you were referring to and you are correct for 2011 but not for 2014

The neutrals of multiwire branch circuit's only need to be identified if there is more than one set in the raceway. If there is a pipe with a neutral and 3 hots then no marker is necessary. If there are 2 pair of these multiwire branch circuit's then you would need to group them.
