uses for 12/4(12/2/2) romex

[elecmen]

Hi, I have a question about 12/4 (12/2/2) romex. I have the type that has a black,white,red and white with red stripe. Can the white with a red stripe be used as a neutral? I would like to use the black and white to feed a GFCI outlet and then use the red and white/w red stripe on the load side of the GFCI to back feed another outlet. The feed goes to an outlet on the ceiling of a garage. I would run the 12/4 from this outlet to an outlet on the wall to get my GFCI protection for the ceiling outlet and make it GFCI and readily accessible. Is this code compliant? Thanks

It is setup with 2 circuits. The white with the red identifies it with its mate, the red wire. It is not called 12/4. 12/4 has a black, red, blue and white wire with a ground , of course. What you want to do with it is fine.

It has a great use now with the use of AFCI through out the whole house and also then you don't have to worry about 210.4(B)

I just wish my local suppliers stocked 14/2/2. :weeping:

14-2-2 is perfect for 3 way switching when you need a neutral at the far end.
