Pulling a color other then green, then taping green. Legal?

What is the reason a # 6 is safe to phase tape green and a smaller wire is not? TIA


Careful, the rule is that EGC conductors larger than than #6 may have insulation other than green and may be re-identified as bonding wires. Neutrals/grounded conductors have similar rules.

The rule is at least 60 or more years old and the exact reasoning on the size of the wire being chosen is unclear to many of us.

It seems like a silly rule, but it is there and not likely to get removed.

LOL!!! No comment!! Trust me, the worse I?ve seen was from Cali!!! I actually said this before, and it only took a few minutes before someone else agreed. This isn?t to say all of them>>>obviously, some of the best are on here!!!! Heck, tell the bad ones to stop moving to WA, they are giving Cali a bad rep., and now WA??. LOL!!! We have bad ones here too, and I?m not the best in the world!! But, trust me, I?ve worked with a few from cali, and every time they was wrong and cutting corners!!!


Not even close. 25 years in California (Bay Area) , and now 7 years in Florida, North central Florida work is hands down worse than California, especially some of the stuff you come across that was done in the 70's!!!!!!!!!!!!!

Just strip it

Just strip it

Although you cannot tape grounding wires smaller than #6 with green, you can strip the wire where it is exposed and meet the marking requirement.

The rule is for conductors smaller than #4, and you can not just strip the exposed insulation - it must be green or green with yellow stripes its entire length.

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.

Well trust me, I've seen the same thing, but then I've never really looked at work in other states.:happyno:

Luckly I fall into the "one of the best" group.:D

That used to be correct, but most wire manufactures now make larger conductors in most colors.

It's true for most US and Canadian manufacturers; however, most other foreign manufacturers still have a #6 cuttoff - and there are plenty. See the UL Online Certifications Directory , check "Display Guide Information only" and search Category Codes ZLGR and ZKST. Click the link to "guideinfo" and in then the "view listings" in the upper left hand corner.

There are actually more foreign manufacturers than domestic since wire is one of the easiest electrical building products to market in the US. Several of the larger foreign manufacturers also can make colored conductors #6 and above, but often still don't except as "special" orders. For most of them it still isn't economically justified.

I didn't have all of that information, but I know for a fact that no one around here carry's any colored wire that large. See my tag line if you want to know how to get it.:happyyes:

Most of the thermoplastics (Cat Code ZLGR) are pretty easy to make in any color, in any size; however, stocking any color other than black over #6, is up to the distributer. They may feel it isn't worth the inventory space, especially at the "branch" level. If they are closely associated with a major US manufacturer's distribution operation, it is usually available fairly quickly - anyone can get it, but it may take a while. As local demand increases, so does the supply (and stocking).

Yes, an EGC can be bare, but it must be bare its entire length

Entire length?

Entire length?

I don't know where the idea that stripped wire would appear to be a grounding conductor. I guess it was by analogy to the fact that a #6 or larger wire could be identified by taping a color only at a termination, rather than its entire length. Perhaps my father taught me that in the 1950's (he was an engineer and they as we all know they have strange ideas about wiring:)).

I do know if I saw a conductor stripped for essentially its full exposed length, I would consider it a grounding wire.

In any event I can find nothing definitive in the code.

It is what it is, silly rule or not. If you re- identify an insulated hot colored conductor smaller than #4 as an EGC or neutral the world will end and pigs will fly.:D

Because when you get into the larger sizes the manufactures only make it in black.

They can make any color in any size. If people are not buying them they will not be made. If NEC decided we will use green/white/gray no matter what size they would become more readily available because there would be a demand.

I know you used to see a lot of #6 with white or green tape around here. Some suppliers were not even stocking in those colors because there was no demand for them. When inspectors started enforcing correctly the demand went up and they are all stocked now - and have been for a long time as this was at least 20+ years ago when this happened.
