Southwire 250ft 14/2 WG NM-B Cable – Romex SIMpull, 600V, 90°C

Description

Product Overview

The Southwire 250ft 14/2 WG NM-B Romex cable is engineered for dependable power distribution in residential settings. Constructed with a non‑metallic sheathing, the cable meets the 600 V rating and is approved for temperatures up to 90 °C, making it suitable for a wide range of indoor applications. Its 14‑gauge, 2‑conductor configuration provides ample current‑carrying capacity while maintaining flexibility for easy installation in tight spaces.

Each foot of cable is manufactured to strict industry standards, ensuring consistent strand quality and uniform insulation thickness. The wire strands are copper‑clad, delivering low resistance and high conductivity, which translates to reduced voltage drop over long runs. The outer jacket is resistant to abrasion, chemicals, and moisture, protecting the internal conductors from environmental hazards.</n

Designed for both exposed and concealed runs, this cable can be installed in open air, within conduit, or directly behind drywall and plaster. It is also approved for use in masonry voids where walls are dry, allowing electricians to route wiring through brick or block without compromising safety. The product dimensions—14 × 14 × 3 inches and a weight of 14.32 lb—make handling and storage straightforward on job sites.

Southwire, a leading name in electrical solutions, backs this cable with a reputation for quality and reliability. The product carries a National Stock Number (NSN) of 6145‑01‑586‑3612, reflecting its compliance with military and government specifications. Since its introduction in 2008, the cable has earned a solid customer rating of 4.8 out of 5 stars from over 2,000 reviews, highlighting its performance and durability.

Key specifications include:

• Length: 250 feet (76.2 m)
• Conductor size: 14 AWG
• Number of conductors: 2 (plus ground)
• Voltage rating: 600 V
• Temperature rating: 90 °C
• Approved for dry locations, concealed or exposed

Usage

This cable is ideal for new residential construction, remodels, and additions where reliable power distribution is essential. Installers can use it to feed lighting circuits, outlet branches, and dedicated appliance lines such as for kitchen ranges, dryers, and HVAC equipment. Its flexibility allows it to navigate around joists, studs, and other structural elements without excessive bending.

Because the cable is rated for dry locations, it is perfect for interior wall cavities, attic spaces, and crawl spaces where moisture is not a concern. Electricians often run the cable through masonry block or tile walls, taking advantage of its ability to be placed in air voids without additional protection. The 600 V rating ensures compatibility with standard residential loads, while the 90 °C insulation provides a safety margin for higher‑temperature environments.

For contractors working on large‑scale projects, the 250‑foot length reduces the need for multiple splices, minimizing potential points of failure and saving installation time. The cable’s robust outer jacket also withstands the rigors of commercial‑grade tools and equipment, making it a versatile choice for both professional electricians and skilled DIY homeowners.

When used in conjunction with proper grounding and circuit protection devices, this NM‑B cable contributes to a safe electrical system that meets or exceeds local code requirements. Its compatibility with standard connectors and devices ensures a seamless integration into existing wiring infrastructures.

Why Choose Us

Southwire’s commitment to quality is evident in every strand of this NM‑B cable. The company employs rigorous testing protocols, including tensile strength, elongation, and insulation resistance assessments, to guarantee that each roll meets the highest performance standards. This dedication results in a product that consistently delivers reliable power without premature degradation.

Our cable’s non‑metallic sheath not only simplifies installation but also reduces the risk of corrosion over time. Unlike metallic‑sheathed alternatives, the NM‑B jacket does not conduct heat, helping to maintain the cable’s temperature rating even in confined spaces. This characteristic enhances safety and prolongs the service life of the wiring system.

Customer support is a cornerstone of the Southwire experience. Buyers receive access to technical resources, installation guides, and a responsive helpline staffed by knowledgeable professionals. Should any issues arise, our warranty and after‑sales service provide peace of mind, ensuring that you can rely on the product for years to come.

In addition, the cable’s competitive pricing reflects its value proposition—high‑grade materials and performance at a cost‑effective rate. This balance makes it an attractive option for contractors seeking to stay within budget without compromising on safety or durability.

FAQ

Can this cable be used in wet or damp locations?

No. The NM‑B cable is specifically rated for dry locations only. For wet or damp environments, a different type of cable such as UF‑B or THHN should be selected to meet code requirements.

What is the maximum temperature this cable can handle?

The cable’s insulation is rated for continuous operation up to 90 °C (194 °F). This rating allows it to be used in areas where higher ambient temperatures may be encountered, such as attics or near heat‑producing appliances.

Is this cable suitable for conduit installations?

Yes. While the cable is designed for direct burial in dry interior spaces, it can also be run inside conduit when additional mechanical protection is desired or when local codes require it.

How many circuits can I run with a single 250‑foot roll?

The number of circuits depends on the amperage of each circuit and the total load. The 14/2 configuration is typically used for 15‑amp lighting and outlet circuits. For larger loads, multiple rolls or a larger gauge cable may be necessary.

What warranty does Southwire provide for this product?

Southwire offers a limited warranty that covers manufacturing defects for a period specified in the product documentation. Customers can contact Southwire’s support team for warranty claims and technical assistance.
