I believe that literally speaking, it violates 200.6(A). The "colored tracer threads in the braid" statement doesn't apply here. 200.6(D) seems explicit in it's intent.
That being said, I think this stuff will probably be approved in many residential applications.
Wire is quite cheap right now, and it has been for the past few years. $.08 a foot sounds similar to prices around here (new england). Enjoy these prices while they last!
Code issues aside, this new cable is also great for electricians who don't like using multiwire circuits.
Redsy, I agree that it has a good use and will most likely be accepted by the AHJ, but it is a code violation. Maybe we'll see proposals from Southwire for a 2005 change. Don(resqcapt19)
'66 Thats a good question, if the neutrals are considered current carrying conductors then we would have to derate 80 %, Right ? But for derating purposes can we not use the table 310.16 which gives No.12 at 25 amps and the 80 % would be 20 amps???
On the 4-wire romex, don't forget the soon-to-be onslaught of Euro-crazed demands for residential 3-phase receptacles and appliances! NEMA anticipated this long ago with L21-20 and L21-30 wiring devices. Be sure and stock up on ‘em on your next trip to the supply house.
