Beyond the multiple voltage thing John mentioned and the orange on a high leg delta, it will be hard to find a violation if the phases are not identified.

I once had a spec job that wanted an odd color #10 THHN stranded. It was a 'special order' 10K feet minimum.

Client (engineer) said.." cost is no issue, follow the spec, and order it"

We used less then 200' total to one electronics rack, the balance went to their warehouse.

Ironically, when they went 'belly up', they gave it back to me. It was 'pink' or 'light red' and went to other jobs.

Sorry; I keep forgetting that we tend to have slightly different rules here than in the NEC.

Chicago - 210.5
208Y/120 gets marked Black, Red, Blue
240V Delta gets a Red high leg
277/480 gets marked Brown, Orange, Yellow

The 208 and 408 wye is standard enough that MC manufacturers are making it up that way with the color code on the armor. I really thought that was cool the first time I saw it on a job.

It is not only informative, it is pretty wink

They also had special cables for fire and patient care area circuits.

Pink tape exists? Amazing! I'll have to get some, just to annoy folks. I see an April 1st visit to the parts house coming up .....

As for color codes, it's important to know the difference between 'practice,' specification,' and 'requirement.' That was the point of my post.

I suppose that after a while common practice (like black, red, blue and BOY) drives manufacturers to create products then regulation follows because manufactures drive the CMP process.
The other "standard" seems to be violet/gray for 277 circuits. It does seen to keep most people from trying to get 120v from a 277v lighting circuit ... but not always. Kaboom!

An interesting side note....

Our POCO (PSE&G) does NOT allow the "O" in 'BOY' within their meter pans or CT cabinets, or pad mount transformer secondary.

It is noted within the utility spec book.

Reasoning? Safety! 'Orange' tape or insulation in their eyes indicates 'High Leg' 'Red Leg' 'Bastard Leg' 'Wild Leg'

The 'old timers' know the difference, but the concerns are for the 'newer guys'.

I have not worked in the JCP&L territory recently, so I will have to check their site for specs unless someone here knows.

The fact that NFPA decided orange should be the high leg on center tapped delta was unfortunate since BOY has become so much of a standard.
That was where the pink wire should have gone wink

I fess up to you, it was not thoroughness at all; I had a glitch in the internet connection. I should have checked before I shut down...
