The 2005 NEC will include a new requirement stating that green insulation or green with a yellow stripe are only permitted to be used for the identification of the equipment grounding conductor.

The proposed wording says that any conductor "identified as permitted" in this section shall
only be used as an EGC. The use of a bare wire is permitted to identify an EGC, this will mean that bare conductors are no longer permitted to be used as grounding electrode conductors.

West-Southern Inner-Northeast ...
Is there a similar proposal for white and white/red colors with grounded-circuit conductors?

The hazards seem similar to those cited by Phil Simmons for green and green/yellow.

Don:

I think that the new sentence makes it clear that the color green or green with a yellow strip will not be allowed to be used to identify the GEC.

The comment stage is where any changes proposed to the original accepted actions can be made by any person who wants to send one in.

What would we do with all that bare solid larger than #10? [Linked Image]

So then an exception to the rule above may be in order"

"Exception: Grounding electrode conductors shall be permitted to be bare."

Joe,
You are correct that the new wording would prohibit the use of green for the grounding electrode conductor. My comment will be to "accept in principle" with the following words added at the end of the proposed wording, "or grounding electrode conductor".

Why not identify the EGC with green and yellow stripes only and the GEC with green (or bare) only. Then the US would follow the international standard on the EGC identification [Linked Image] (I don't think there is a standard for the GEC)
