3-phase loadcenters with 2P circuit breakers; N required?

[Team-MEI]

I have several exterior 3-phase loadcenters with only 2P branch-circuit breakers present in the loadcenters. I cannot find an NEC section which requires a neutral in this situation. Dismissing the several merits for having the possible availability of 1P branch loads if a neutral was present; is there a code which requires a neutral where the branch loads are all 2P? I know if I do run such a neutral that it cannot be downsized per 220.22. I cannot find any special code required labeling either which would show ?no neutral present?; is there a special caution labeling requirement for this situation? I ran 2-hots and a properly sized EGC to each but no neutral. Thanks in advance for your comments.

There is no NEC requirement that a grounded (neutral) conductor be brought to a remote panelboard. There is also no requirement for labeling the panel to indicate that there is no grounded conductor present. Tgis would be a design choice.

You must bring a grounded conductor to the service disconnecting means, but after that you don't. (See 250.25(C))
