Southwire Romex SIMpull NM-B 12/2 W/G Indoor Cable, 50ft Coil – 600V, Dry Locations

Overview

This Southwire Romex SIMpull NM-B 12/2 with ground copper cable is designed for general wiring in homes, stores, and shops. The SIMpull jacket helps reduce friction during pulling and stripping, making installations smoother in wall cavities and ceilings. With a 600-volt rating and copper conductors, this cable supports reliable branch circuits for outlets and switches, while staying suited to dry, above-ground environments.

The NM-B construction is crafted for residential wiring needs, combining flame and moisture resistance with practical flexibility.
