Southwire Romex SIMpull NM-B 10/2 W/G Indoor Cable, 50ft Coil | Dry Location Residential Wiring

Overview

Southwire Romex SIMpull NM-B cable is designed for general wiring in homes, stores, and shops. This copper NM-B wire is intended for dry, above-ground installations at conductor temperatures not to exceed 90 C, with ampacity limited to 60 C for typical residential circuits.

Commonly used as a branch circuit conductor for outlets, switches, and lighting, it comes in a 10/2 with ground configuration and is rated for 600 volts. The patented SIMpull jacket helps with pulling, stripping, and installation, making runs smoother and more predictable for both professionals and DIY enthusiasts. The 50 ft coil provides a practical length for many residential projects, reducing joints and maximizing layout flexibility.

Why choose SIMpull NM-B for residential wiring

• Patented SIMpull jacket facilitates easier pulling, stripping, and installation, minimizing effort during runs.
• Copper NM-B construction supports common residential branch circuits for indoor use.
• Dry-location suitability with conductor temperatures up to 90 C and ampacity guidance of 60 C.
• 600-volt rating ensures compatibility with standard indoor electrical systems.

The 50 ft coil size strikes a balance between long runs and manageability, while the 10/2 with ground (W/G) configuration provides the essential conductors for typical outlets and switches. This combination is well-suited for upgrading or extending circuits in living spaces, kitchens, or home offices where dry, above-ground installation is feasible.

Real-world uses and installation notes

• Ideal for dry interior spaces such as living rooms, kitchens, and bedrooms where concealed wall cavities or dry masonry voids are present.
• Can be run in both exposed and concealed installations in dry locations, including above-ground runs in walls or ceilings.

Important considerations: avoid wet locations; this cable is flame and moisture resistant within dry contexts. Always follow local codes and guidelines for maximum conductor temperatures and ampacity. While it supports common residential wiring needs, it is not intended for use in wet environments nor submersed applications.
