Old NM braided jacket color code...?

I don't believe you will find a color code for the size. Even today there is no requirement for this. Use a wire stripper to gauge the conductor. Turn the power off first.

There were many colors and flavors of type NM cables from years past. I've seen blue, white, black, brown, green, tan, and a couple of others I can't think of. Each manufacturer had their own color schemes and even changed them from time to time.

As stated in another post, there are no mandated color codes, even today.

Most manufacturers have voluntarily adopted the white = 14, yellow = 12 and orange = 10 gauge coding system, however.

Thanks for the replies

I will crack open the jbox and check it out. I just try to touch that stuff as little as possible. It is still well insulated but brittle at this point.

Last year I was replacing some outlets and the insulation broke off one of the conductors right at the top/back of the box and no more slack to pull through. Didn't feel comfortable with just rolling on a few layers of tape so it got replaced. Got my butt in gear to add some outlets around the kitchen counter so it worked out.

I really don't want to spend my 4th of July weekend in the attic so I will be gentle with the old stuff.

Thanks Again :thumbsup:
