200.4(B) Exc 1
(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 identifing 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.


So if I have a 1”’emt conduit with 3 ungrounded conductors and 3 grounded conductors AND I label this with numbers near the breakers and on the neutral bar making where these conductors come “obvious” I would not need to employ tie wraps grouping the conductors.
Is this a fair statement?

Still a good idea to tie wrap them. Markers fade out and come off over time. I've seen a lot of headaches from mixing up neutrals. One of the few times I really fought with a boss was over this issue.

I think, I am starting to get the message !
