I found an old coil of 10/3 wg romex. This cable has a white sheath before orange became the standard for 10/3 romex. My question is if I can still use this in new construction? The cable is in excellent condition. I am concerned if It would be flagged because of white sheath instead of modern orange. Thanks.
 
The orange sheath used my some manufacturers for #10 Romex is not a code requirement. I wouldn't hesitate to use the wire you described.

Yes there was a long period where we would get white 90C NM.

As has been mentioned, code wise, UL standard wise, the color means nothing at all.

A manufacturer could choose to use orange for 14 if they wanted.
 
I agree with the comments above. If it is 90C nm cable (NM-B) then the color doesn't matter. The color is for identification purposes for the EC and inspector and is not an NEC requirement.
 
They used to make NM-B in a baby blue sheath. One of our young helpers commented on it once and I told him the color was easier on the hands so he wouldn't need his gloves to pull it. 10 minutes later he was trucking along with his gloves tucked neatly in his tool belt.
 
FWIW, I am aware of one contractor who special-orders his NM with a pink jacket, for all sizes.

His reason for doing so is to discourage theft; local inspectors help him keep an eye out.

if the inside insulated conductors are of the thhn type it should be okay, if the
inside insulated conductors are of the tw type then scrap it or use it for temp
wiring.

Why not use it if it's type TW?

Going from memory I know of nothing to keep you from it as long as the ampacity and OCP is sized to the proper temp. Except for lighting 10-3 is rarely used in lighting.

That'll learn me to not look in the book.
