Color sheath on Romex/NM cable?


My house was built in 1999 and all the wiring through the home other then to the AC and stove is 12/2 or 12/3 Romex. All of it is white sheathed. But when I went to Home Depot to buy more 12/2 all they have is yellow sheathed 12/2 and the 14/2 is white. I then checked my local Carter Lumber and they had the exact same thing, 12 is yellow and 14 is white.

Did they stop selling it all in white so it's easier to tell the difference? I guess it doesn't matter but I wanted to make sure before I buy some. Can I still find white 12/2 and 12/3 to maintain uniformity with what is already installed?

I have not seen white #12 NM for several years. There is no issue with the different color sheath. It does not need to match the older cables.

Color sheath on Romex/NM cable?


I was hoping to buy the same but doesn't sound like they make 12/2 in white anymore. Yes I'm positive its 12ga...the smallest breaker in the box is a 20A and I've checked the wire are multiple places throughout the house with them all saying 12. It's not a big deal for new runs but I was trying to match the old for some extensions (like I have a pull string on a light so I'm going to just put a switch in between and a regular light base....just will look goofy with a 6' piece of yellow with whites going into the junctions in the middle).

Thanks for the quick answers.

Am I understanding correctly that the romex is exposed where it can be seen? Typically that's a no-no, except for example in a garage with open framing.

It is not a code issue yet but has become a sort of industry standard for different gauges to be different colours.

No romex is exposed in the house....this is down at my breaker box. And the place where I'm looking to add a switch in is in my unfinished basement where I can see all the romex runs also. So since I was adding to I was hoping to stay the same color but it's really not a big deal I suppose.

You can always paint the stuff, if you really don't like the yellow.

no you can't. That may harm the insulation and is not legal.

hahaha....no I don't care that much. In all honestly once I put up drywall I'll never see it again other then at the breaker box. And even then I hope I'm not checking my breaker box very often....

110.11 refers to deteriorating agents
Is that the right section ?
If so I guess it would depend upon the paint

I think it may also depend upon when it is painted
I'd never paint anything before Inspection
But I have seen plenty of NMB painted the color of a basement wall

How about a code reference for this one?

Since when is "exposed" NM cable a violation?
What about 334.15?

the basis is: you cannot put anything on the wire that would cause it to deteriorate. Unless you can prove (like in UL listing) that what ever paint you are considering putting on the wire will not deteriorate it, you must consider it as not acceptable.

It may have done nothing but unless you can prove it is acceptable, it is not acceptable.
