Southwire Romex SIMpull 25 ft 12/2 Solid CU NM-B W G Wire - Easier

Our review of the Southwire Romex SIMpull 25 ft 12/2 Solid CU NM-B W/G Wire finds it best suited to DIYers and electricians who need a reliable, easy-to-install residential branch circuit cable for outlets and switches. The single biggest reason to consider this cable is the patented SIMpull Cable Jacket, which noticeably reduces friction when pulling through studs or conduit openings and also makes stripping easier, saving time on typical home wiring jobs.

Key Features

• SIMpull Jacket: The patented coated jacket reduces resistance when pulling cable, making long runs and tight bends simpler and faster to install.
• NM-B Construction: Designed for residential branch circuits, this nonmetallic-sheathed cable is appropriate for outlets, switches, and other general wiring tasks.
• 600 Volt Rating: A 600 V voltage rating provides the standard electrical tolerance expected for building wiring in dry locations.
• Temperature Use: Rated for use in normally dry locations up to 90C while ampacity remains limited to 60C conductor tables, matching common residential code expectations.
• Versatile Routing: Can be run exposed or concealed and through air voids in dry masonry walls where conditions permit, offering installation flexibility.

Who It's For

This cable is a solid pick for homeowners doing rewiring projects, garage or shed circuits, and professional electricians who value smoother pulls on repetitive jobs. The 25 ft length and SIMpull jacket are particularly useful for runs through finished walls or long runs where cable grabbing and snagging are common frustrations.

It is not intended for wet or underground use, nor for installations that require metallic conduit or specialized jacket materials; those needing outdoor-rated or direct-burial cable should look elsewhere. Also, projects requiring wires larger than 12/2 or different conductor types warrant a different product.

Pros & Cons

Pros

• Easy to pull jacket meaning faster installs and less strain on the cable during routing.
• Common NM-B construction suitable for most residential branch-circuit work, simplifying material choice.
• Good value and adequate length for many room-to-panel runs, as customers note the functionality and length.

Cons

• Designed for dry, above-ground locations only, so it cannot be used outdoors or in wet/damp conditions.
• Some users report mixed opinions on long-term durability, so heavy-abuse environments may need more rugged cable.
