Southwire 28828255 250 ft 12-2 NM-B Wire - Reliable Residential Cable

In this review the Southwire 28828255 250 ft 12-2 NM-B Wire is assessed as a practical choice for residential wiring projects where a durable, easy-to-pull cable is needed. The biggest reason to buy is its dependable construction for general branch-circuit work: the Romex SIMpull NM-B design and smooth jacket make routing through attics and walls straightforward while meeting the typical voltage and temperature needs of home installations. This review highlights who will get the most value and the cable limitations to keep in mind.

Key Features

• Type: NM-B nonmetallic-sheathed cable suitable for both exposed and concealed work in normally dry locations, providing flexibility for many residential installation scenarios.
• Length: A 250 ft spool gives installers a substantial run for outlets and switches without frequent joins, reducing installation time on medium-sized projects.
• Temperature rating: Rated for conductor temperatures up to 90C which allows safe operation in warm environments while ampacity is managed at 60C for standard branch-circuit loads.
• Voltage rating: A 600 volt rating covers typical residential and light commercial wiring requirements, offering compatibility with standard household circuits.
• SIMpull jacket: The smooth Romex SIMpull jacket eases pulling through studs and conduits, which customers report improves ease of use and reduces snags.
• Grounded conductors: Includes a ground conductor for proper safety and compliance with modern electrical codes in branch circuits.

Who It's For

The Southwire 12-2 NM-B is best suited for electricians, contractors, and DIYers working on residential branch circuits for outlets, switches, and general lighting where runs are in dry locations such as attics, basements that are dry, interior walls, and ceilings. Installers who value a smooth-pulling jacket will appreciate the reduced effort when fishing long runs.

It is not intended for wet or continuously damp locations, so homeowners needing outdoor, underground, or wet-area wiring should look for cables rated for those conditions or conduit-protected wiring methods. Also, projects requiring larger gauge conductors or specialized cable types are outside this cable's intended use.

Pros & Cons

Pros

• Well-made construction that customers describe as durable and reliable for residential wiring tasks.
• Good value for money given the 250 ft length and solid SIMpull jacket that eases installation.
• Versatile for exposed and concealed work in dry locations thanks to the NM-B rating and 600 volt capacity.
• Grounded 12-2 configuration matches common branch-circuit needs for outlets and switches.

Cons

• Not suitable for wet or damp locations, so additional products or protection are required for those environments.
• Some users report the 250 ft length may be insufficient for very large projects, requiring additional spools.
