Wiring sub panel, can I use all black wires?

[Strouty]

I am trying to wire up a 100 amp sub panel. I have a bunch of #2 wire, but it is all black. Can I just color code it with electrical tape?

I know I can do it, I am asking if there is an issue with code if I do it.

 

[Ameriman]

There won't be an issue with code if you were to do that. It is common practice to "phase" your conductors with the appropriate colors for that "phase". So, no problemo!

 

[Strouty]

Awesome! I have a limited budget and when I found all the wire I was excited. Now I can put that money towards some bills.

This is referring to the neutral conductor.

200.6 Means of Identifying Grounded Conductors.
(A) Sizes 6 AWG or Smaller. An insulated grounded conductor of 6 AWG or smaller shall be identified by one of the following means:
(1) A continuous white outer finish.
(2) A continuous gray outer finish.
(3) Three continuous white stripes along the conductor’s entire length on other than green insulation.
(4) Wires that have their outer covering finished to show a white or gray color but have colored tracer threads in the braid identifying the source of manufacture shall be considered as meeting the provisions of this section.
(5) The grounded conductor of a mineral-insulated, metalsheathed cable shall be identified at the time of installation by distinctive marking at its terminations.
(6) A single-conductor, sunlight-resistant, outdoor-rated cable used as a grounded conductor in photovoltaic power systems, as permitted by 690.31, shall be identified at the time of installation by distinctive white marking at all terminations.
(7) Fixture wire shall comply with the requirements for grounded conductor identification as specified in 402.8.
(8) For aerial cable, the identification shall be as above, or by means of a ridge located on the exterior of the cable so as to identify it.

(B) Sizes 4 AWG or Larger. An insulated grounded conductor 4 AWG or larger shall be identified by one of the following means:
(1) A continuous white outer finish.
(2) A continuous gray outer finish
(3) Three continuous white stripes along its entire length on other than green insulation.
(4) At the time of installation, by a distinctive white or gray marking at its terminations. This marking shall encircle the conductor or insulation.

This is in reference to the equipment grounding conductor (EGC)

250.119 Identification of Equipment Grounding Conductors.
Unless required elsewhere in this Code, equipment grounding conductors shall be permitted to be bare, covered, or insulated. Individually covered or insulated equipment grounding conductors shall have a continuous outer finish that is either green or green with one or more yellow stripes except as permitted in this section. Conductors with insulation or individual covering that is green, green with one or more yellow stripes, or otherwise identified
as permitted by this section shall not be used for ungrounded or grounded circuit conductors.

(A) Conductors Larger Than 6 AWG. Equipment grounding conductors larger than 6 AWG shall comply with 250.119(A)(1) and (A)(2).
(1) An insulated or covered conductor larger than 6 AWG shall be permitted, at the time of installation, to be permanently identified as an equipment grounding conductor at each end and at every point where the conductor
is accessible.
Exception: Conductors larger than 6 AWG shall not be required to be marked in conduit bodies that contain no splices or unused hubs.
(2) Identification shall encircle the conductor and shall be accomplished by one of the following:
a. Stripping the insulation or covering from the entire exposed length
b. Coloring the insulation or covering green at the termination
c. Marking the insulation or covering with green tape
or green adhesive labels at the termination

 

[Strouty]

So I don't need to mark the entire length, just where it is exposed inside the box or panel?

 

[Ameriman]

Yeah, just the ends of the wire after you strip back some of the insulation.

I will post some pictures, but they will be in this thread.
