Gotta jump in here, although someone will dispute me. Just went out to the shop to check a sample.
There is a small difference in description between extension cord wire & building wire.
3/12 ext wire has black-hot, white-neutral, green-ground. It does not have a bare wire.
3/12 building wire has black-hot, red-hot, white-neutral. It does not have green or bare.
3/12 w/ground (marked on the jacket) will add the bare ground. The ground in this case will be 1 wire size smaller than the hot/neutral wires. Eg- in 3/12 w/gnd, the gnd will be #14.
It is perfectly legal, proper, & safe to run 3/12 w/gnd to feed 2 circuits. 1- black hot, 2-red hot, tie the white neutral to both outlets, tie the bare gnd to both. Neutral & gnd are not tied to each other. However sometimes it is easier to run seperate 2/12 w/gnd to each outlet so the box doesn't get so crowded.
Then there is what is commonly called Romex. That stuff went out with whip sockets, single trees & high button shoes. Romex is that old rubber insulated, fabric jacket stuff. What is commonly called Romex is type NM, (Non Metalic) sheath, for use in dry, inside building locations. Type UF is for use in damp, wet, even direct burial locations.

Let�s examine the purpose and design of these fasteners in order to ensure their proper use. Fasteners are probably one of the aspects of mechanics that is given the least amount of thought.
