So I walked a sizable job with an inspector yesterday, mostly just to let him in for my boss to show a resolved issue and there are a few runs between machines that have a EGC pulled in. The inspector commented that 'yellow with green stripe' is not allowed per NEC. It was not the main issue at all but he said he did not want to see it in the future. I said I would put green tape on it and he said not allowed either? The wire did look mostly yellow with a green stripe. Where is this covered in the NEC? Thanks
Yellow with green stripe as EGC?

250.119. Green with a yellow stripe is allowed, but yellow with a green stripe is not allowed.

Is it really yellow with a green stripe? Or green with more than one yellow stripe? I'm guessing that a yellow conductor with a green strip is not even readily available.
Yeah we both looked at it really close in several places, its entirely yellow with a very small green stripe.
I should have got a photo but I am not all technical like most of you.
The inspector say he has been seeing this and was asking questions about it, like whos selling it.
I was just trying to get home it was Friday at 4.

I was wondering that too, where are they getting this product because it doesn't seem like it would be used very often.

Was it wire already installed as some part of an assembly? Like many of the products supplied from overseas.
It was regular 12 THHN like this:

Well that's yellow TFFN with a green tracer. IMO that is a yellow conductor.

I don't see how you could use it as a hot with that green stripe.
In my opinion this is just silly. Green with a yellow stripe or yellow with a green stripe. What's the difference? Because the NEC says so? And why is that?

If are you proposing its splitting hairs and its OK to use yellow wire with a green stripe as EGC I tend to agree.
If its not allowed as a EGC, it can't be a noodle,
then what are the other options other than a hot?
Thanks

I'm guessing that this wire was cheap surplus.
My understanding is that green is used as a hot in traffic light applications, where the wire colors match the light colors. There will also be tracer colors to organize which signals the wires are going to.
