I haven't used any or ever priced any. But if it is 3 times the cost of using two - two wire cables - it would need to be a situation that could save some labor or I will not be using it. I may even prefer a raceway method in some instances. It will have less copper then two 2 wire (with ground) cables because you will only have one equipment grounding conductor, but price is likely high simply because it is not as fast of a moving item as two and three conductor cables.What situations would a person use 12-2-2 and 14-2-2 NM? I'm sure it comes in handy but it's price is about 3 times the cost of 12-2 and 14-3..... ?
All valuable ideas so far. In another thread I described a 3 way switch situation where it comes in handy. In residential kitchens, a 12-2-2 Romex to the microwave with the extra circuit used for a SABC. Anytime that you can make one home run & get two circuits=less labor. Do your own cost analysis & see where you wind up. I like 14-2-2 &
12-2-2

Best use for the stuff no doubt AND the added benefit of fewer EGC's to have to make up in the panel or stuff in j boxes.Usually you can pull more than one home run at a time. I would guess three home runs at a time is typical unless you have a really great setup with multiple reelers.
So if your average kitchen needs 6 circuits, you can pull them all at once. One 12-2-2 for the sabc, one 12-2-2 for the microwave and dishwasher/disposal circuit, and one 14-2-2 for all the lighting.
