Control wiring - green okay?

[LarryFine]

The title pretty much says it: Can green be used as control wiring for other than grounding? Specifically, the 16-18ga. control wiring for a residential generator.

Colors are normally black, white, red, yellow, and 2 blue. Can green be used if I have no yellow? (Yes, I know I don't have to match colors, just tell them apart.)

Would 250.119 Execption 1 apply?

Would 250.119 Execption 1 apply?

Nope. It's for cables, but even then, my raceway would contain line-voltage conductors, too.

What voltage is the control wiring? Green is commonly used for low voltage control color coding. The thermostats in your house probably use a green wire to control the fan.

Some of the control wiring in a Generac carry 120v, and some just 12v dc. The wire I have is MTW, by the way, 16 and 18 ga.

Would 250.119 Execption 1 apply?

I think so.

I'd use the green for 23 or 194 since they are the low voltage and not the N1, N2 or T.

Every A/C we've ever wired Green #18 is pulled for the fan signal.

250.119 Execption 1 applies there.

This makes me cringe. I'd file in this in the, "just because I can, doesn't mean I should" category.

Can you not find some shorter cuts on Ebay, Amazon, have HD cut you some, etc?

To clairify we pull individual conductors. in EMT, not cables.

According to the above-mentioned code exception, it applies to a green conductor in a cable that contains a green conductor, but no line-voltage conductors.

Does that mean no non-EGC green in a conduit or other raceway, regardless of the presence of line voltage?

Industrial world red and white used 120 AC, blue always DC and yellow is control feed from another source such as interlock between equipment..
