NM-B Temp Rating?

[nwav8tor]

My 120/277v light fixtures specify using 90C conductors. Does standard 14-2 w/Grnd on a 15A circuit meet this requirement? I can't find a temp rating anywhere on the NM-B I have.

Thanks,
Paul

NM-B is rated at 90c, it was changed in 1984.

NM is rated at 60c.

NM-B is rated to 90C. You use the 60C rating for amp capacity.

Thanks guys. That's what I was hoping to see!
