(C) Circuits of 50 Volts or More. The use of insulation
that is white or gray or that has three continuous white
stripes for other than a grounded conductor for circuits
of 50 volts or more shall be permitted only as in (1)
through (3).
(1) If part of a cable assembly and where the insulation is
permanently reidentified to indicate its use as an ungrounded
conductor, by painting or other effective
means at its termination, and at each location where the
conductor is visible and accessible. Identification shall
encircle the insulation and shall be a color other than
white, gray, or green.

The way I read this is 200.7(C)(1) is that if the white-insulated wire is part of a pre-fabricated cable assembly (e.g., Romex) with some type of outer jacket. Am I reading this correctly? Or can individual conductors pulled into a raceway be considered a "cable assembly"?

Let me explain my situation. Another electrician was wiring up an air conditioning unit on Saturday but got injured on the job and is unable to work for at least this next week. Management asked me today to go in and finish the job. I discovered that the previous electrician pulled, into the EMT conduit, two AWG 6 conductors with red jackets, one AWG 6 conductor with a white jacket, and one AWG 10 EGC with a green jacket. He also had installed a two-pole breaker in the load center. There's only one problem: the air conditioning unit is 3-phase. So now the question is, do I pull the white-jacketed conductor out and replace it with a non-white/non-green jacketed conductor, or can it be "reidentified" with tape?
 
To me 200.7(c) allows you to reidentify the grounded conductor only if it's in a cable or cord assemblies
where the neutral cannot be replaced with the correct color.

You have conductors installed in Conduit which is not a cable or cord.

That is my interpretation as well. But I wanted to make sure I was not being too "technical" about it. It's a long run so it won't be an insignificant cost to replace the white conductor.

Yes. You need 3 non-white/non-green jacketed conductors for your 3 phase supply.

Are you replying "Yes" to the first part of the quoted question (pull the white wire and replace it) and not the second part ("reidentifying" the white wire with tape)?
