I did an install and wired a phase conductor of a 120/240 3w circuit with some orange I had around.

Did I violate?

Thank you
 
I have used a bunch of left over "high voltage" MC cable in my house with brown, orange, yellow and gray conductors.
 
Correct? even the neutral in 120/240 could be gray?



I'm thinking, that BrnOrgYelGry and BlkRedBluWht would only be observed when these different voltages are present at the same point. (in a box or conduit)??

Yup, NEC does not mention color. Only when 2 voltages exist in a building they somehow be identified.

The NEC restricts the use of the following colors
White 200.6
Gray 200.6
Green 250.119
Orange 250.36
Light blue 504.80
Orange with a stripe 517.82 (5)
Brown with a stripe 517.82 (5)
The NEC used to have a color code requirement but it was removed in about the 1976 version.

250.36 is grounding and bonding, more specifically a resistance grounded system?

I assume that you wanted to say 230.56 for the reference to the use of orange, but that rule and the other rules that suggest the use of orange to identify the high leg of a 4 wire delta system do not limit the use of the color orange for other applications.

Any idea why that section exists in 230 when 110.15 pretty much covers it anyway?

I don't like how they say "shall be durably and permanently marked by an outer finish that is orange in color" but then counter the orange requirement by following with "or by other effective means". Is the intent to restrict the use of orange for marking high leg conductors or not? If not then why mention orange in the first place?

It is not that a big of a deal for me, but I am used to seeing high leg systems on a regular basis, I don't necessarily trust markings by others or lack of markings for that matter, and generally figure out a high leg is present pretty quickly even if not identified very well. But there are those that seldom if ever see them that are surprised when they encounter one.

Thank you..

went through those articles, couldn't find mention of Orange in 250.36 high impedance grounding...??

Thank you Mr. Baker
