Saw this in the store. 12-2-2. NM-B 4 conductor with ground. I was just curious to the typical application for such a cable.
Curious about 12-2-2 cable.

Google on "12-2-2 AFCI"
Wiring manufacturers came out with this as a substitute for 12/3 and 14/3 when those circuits will be used for bedrooms protected by arc fault circuit interrupter breakers. Instead of a shared neutral for two circuits, you would now have a separate neutral for each, but one common grounding conductor. I'm not sure how much this stuff is used by contractors even though it can save on labor costs.
Why color do "they" make the second neutral?

Certain protective devices like GFCI and AFCI breakers cannot supplie circircuits with a shared neutral. So x-2-2 seemed to have come into their own.
