Wire phasing

[michael brady]

I know that you cannot use phase tape on grounded conductors that are #6 or smaller and that you can use phase tape on ungrounded conductors of any size. My question is......can you use phase tape on a green wire so that it can be used as an ungrounded conductor?

Nope. If it's green it's only allowed as an equipment ground. 250.119

There is no prohibition against using a green conductor for a GEC, MBJ, etc. It just cannot be used as an ungrounded or grounded conductor.

Good point.

250.119 is about terminals. I was asking about using phase tape on a green wire. I can't find the code section that addresses that. Please advise if you know the code section. Thanks for the reply.

250.119 is about terminals.

Where are you reading that? Here is 250.119, notice the heading.

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.
Exception: Power-limited Class 2 or Class 3 cables, power

I should add to be sure you read 250.119 (A) and (B)

Thanks for the info. I have an older code book and obviously the subject matter of 250,119 has changed over the years. I need to get an updated code book. Thanks again.

It is true that the colour green was not reserved for grounding until 2002 or 2005.

I guess, your code book must be before 1999.
