Southwire SIMpull NM-B 10/2 W/G Indoor Cable, 25 ft Coil | Romex 600V, SW 28829021

Southwire SIMpull NM-B Cable for Residential Wiring

Designed for general wiring in homes, stores, and shops, the Southwire Romex SIMpull NM-B cable delivers reliable copper performance in dry, above-ground locations. With a 600-volt rating, this 10/2 with ground (10/2 W/G) cable supports common branch circuits such as outlets and switches, while maintaining flexibility for indoor runs in weather-protected spaces.

What makes this NM-B cable stand out is its SIMpull jacket—engineered to ease pulling, stripping, and installation, reducing friction through walls and conduit. The copper conductor and jacket are tailored for residential wiring needs, giving you a practical solution for everyday electrical projects in dry environments.

Key benefits at a glance

• Patented SIMpull jacket enables easier pulling, stripping, and installation.
• Commonly used for residential branch circuits feeding outlets and switches with copper NM-B wire.
• Suitable for above-ground, dry locations and for routing through air voids in masonry walls not exposed to moisture.
• 600-volt rating aligns with typical household electrical requirements.
• Designed for dry indoor use, with ampacity considerations based on 60°C conductor ratings.

Usage notes and safety considerations

From the manufacturer, this NM-B cable supports general wiring for homes, farm buildings, stores, and shops. It is flame- and moisture-resistant but should not be used in wet locations. NM-B copper wire is primarily employed as a branch circuit for outlets, switches, and other loads. Installations are intended for above-ground, dry locations with conductor temperatures up to 90°C; however, the ampacity is limited to the 60°C conductor rating. The cable carries a 600-volt rating for typical residential projects.

Real-world scenarios

Imagine running NM-B cable through wall cavities to power a living room outlet cluster or a hallway lighting circuit. The dry, above-ground design tolerates typical attic or basement runs where moisture exposure is limited. In small commercial spaces, such as shops, the cable can form a straightforward backbone for branch circuits, offering manageable pulls and clean terminations.

What to consider before you buy

• Check current electrical codes and local requirements for your project.
• Plan for dry-location use and protect runs from physical damage in exposed areas.
