Check out www.southwire.com Does anyone else think this cable should have been invented a long time ago?

"Historically, contractors have used three conductor cables and a shared neutral for two bedroom circuits to reduce the labor costs over installing two cables," explained Dave Mercier, technical director for Southwire’s Electrical Division. "However, with the newly required AFCI breakers for bedrooms, many builders must now use separate neutrals when two circuits are needed. Southwire’s new 2/2/conductor cable with two neutrals solves this problem for the contractor while continuing to offer labor savings and convenience," he added. would'nt 2P AFCI's be simpler, as well as easy on the box vol, 3 vs. 4 wires...

Is white with a red stripe legal for a neutral?
I do like the new colored jackets; nice design decision.
On a side note: Is copper really cheap for everyone right now? I've been getting Rx 12-2-G for $0.08 per foot, which is a really good price for around here.

Great idea leave it to the manufactures to find a way to capitalize on a change we’ve all been moaning over.
Hope my supply house gets some real soon!!!

I'm not a residential man but why not just pull two 12/2 w/g's. Just seems like something else to have to buy.

I've never liked using 3 wire to vrun 2 circuits because you have to use a common trip breaker and later someone thinks its a 220(240) circuit. So if the wire isn't more than 2 times as expensive, I could see using this alot to run home runs in lots of areas. Just think you can run one wire for 2 kitchen small appliance circuits or as Southwire says, 2 bedrooms.
I also like Southwires new color coding, we now can keep our 14 and 12 separate. If they would only make more colors like cat5 has to keep circuits color coded.

Sparky, Is white with a red stripe legal for a neutral? That is a good question. It appears to me that the stripe is only permitted for a "second system" grounded conductor. Is a grounded conductor for a second circuit a "second system"? D) Grounded Conductors of Different Systems. Where conductors of different systems are installed in the same raceway, cable, box, auxiliary gutter, or other type of enclosure, one system grounded conductor, if required, shall have an outer covering conforming to 200.6(A) or 200.6(B). Each other system grounded conductor shall have an outer covering of white with a readily distinguishable, different colored stripe other than green running along the insulation, or shall have other and different means of identification as allowed by 200.6(A) or (B) that will distinguish each system grounded conductor.

Electric Eagle, you are not required to use a common trip breaker when using three conductor cable for multi-wire circuits.

I like the colored NM cables.
Don,
I know you know this. Different systems refer to different characteristics or sources.
caselec,
If the multi-wire circuit terminates on a single strap in a residential application, a double pole breaker is required.

Redsy,
So then the use of this cable is a violation of 200.6.
