Per 200.6 A the grounded conductor #6 and Smaller must be continous white or grey. Per 250.119A grounding conductors larger than #6 are allowed to be marked at the time of installation. Therfore, the neutral (grounded) or equipment bond(grounding conductor) #6 or smaller will need to be continously marked or factory color coded according. My question is how about the ungrounded conductors #6 and smaller. 210.5 does not specify a size limitation, however, local inspectors are requiring all #6 and smaller to be factory colored. This is not usally a problem with #10 and smaller but #8 and #6 is not always stocked a supply houses in colors especially XHHW or is on the job.

Is it a code requirement to mark the entire length of #6 and smaller ungrounded or phase conductors? Is phasing tape acceptable?
 
Ungrounded conductors are not required to be ANY color (save a few exceptions). They just can't be white, gray, or green per 310.12...

And what code section to they use to support this?
 
The few times it has caused a big problem and I have asked the inspectors they site 90-4. It has been my guess, that the fact it is required for your gournd and neutral, it is being interpreted or stretch by some "local authorities" to be required for phase conductors as well.

Thanks for your responses, I was curious whether or not I was missing something.
 
Is this what you are asking about?

210.5 Identification for Branch Circuits.
(A) Grounded Conductor. The grounded conductor of a branch circuit shall be identified in accordance with 200.6.
(B) Equipment Grounding Conductor. The equipment grounding conductor shall be identified in accordance with 250.119.
(C) Ungrounded Conductors. Where the premises wiring system has branch circuits supplied from more than one nominal voltage system, each ungrounded conductor of a branch circuit, where accessible, shall be identified by system. The means of identification shall be permitted to be by separate color coding, marking tape, tagging, or other approved means and shall be permanently posted at each branch-circuit panelboard or similar branch-circuit distribution equipment.
 
Yes, it is clear what is required by for the grounded conductor and grounding conductor. And per 210.5C I can theoretically use phasing tape to mark #14 thru # 500 and up. Now we do not do that, but because of 210.5 A&B, I think inspectors and other electricians are saying it is required for # 8 & 6. Our standard is to always the colored wire for #14, 12, & 10, but hate buying colored # 8 and 6, because my scrap pile of misc reals is growing faster now that we are using more and more colored # 8&6, and the smaller sizes (#14 thru #6)it is not always readily available in XHHW.
 
As JWelectric gave the code section....... If you have more than one voltage system in your building then a "color scheme" must be chosen to identify the different systems.

As far as your inspectors code section goes....... it's BS with a capital BS.

Everything that is bought on a reel that is in my vans and warehouse looks like it came from an old Ford plant.

The inspector, builder or owner can have any color they want as long as it is black.
 
Mike, the OP said that they give him 90.4 as the refrence. Sound familiar?:grin: Is there some local code that requires this or does the local inspector just make up up his own rules?
 
(C) Ungrounded Conductors.

Do the use of the words premise wiring system imply that the different voltages are installed within the same system, meaning raceway, box, etc.?
If a building had completely separate systems, say one for 277/480 and one for 208/120 would it be required to permanently post a sign a each panelboard?
