Answer

Southwire Romex® Brand SIMpull® NM-B cable is manufactured as 2, 3, or 4 conductor cable, with a bare ground wire. Copper conductors are annealed (soft) copper. Stranded conductors are compressed stranded. Conductor insulation is 90°C-rated polyvinyl chloride (PVC), nylon jacketed. Romex® Brand SIMpull® NM-B cable is designed for easier pulling, resulting in easier installation. The cable jacket is color-coded for quick size identification; White - 14 AWG, Yellow - 12 AWG, Orange - 10 AWG, and Black - 8 AWG and 6 AWG. it is not recommended for individual use. The above advice is based upon the current edition of the National Electric Code (NEC). Free access to the latest version of the NEC is available online at www.nfpa.org/freeaccess. The NEC and local building codes regulate the types of wire and cable that can be used in specific electrical applications, as well as the manner of installation. Check your local building codes before you start any wiring and cable electrical project and be sure to obtain required permits. When your work is complete, always have it inspected for compliance with local codes to ensure that it has been safely installed.

How can you rate the wire when you purchase it. I had no problem finding the correct wire in the electrical department. The only comment is this wire is very expensive to buy so I will only give it a four star.

Easy to cut and wire into existing wires. Love the thickness of the wires not very easy to bend. I really needed a 12/2. Not a 12/3 however this is what the salesman recommended to wire up a outside ceiling patio fan with remote. Made it work i just had to tie off the 1 extra wire. Overall great product.
