14/2 NM-B Copper Building Wire with Ground, 600V (White Jacket)

The foundational wire for residential electrical systems, this 14 AWG NM-B Copper Building Wire is the industry standard for 15-amp lighting and general-purpose circuits. Featuring two high-conductivity copper conductors and a dedicated bare ground, this cable is encased in a classic white jacket for immediate identification, providing a reliable and cost-effective solution for interior residential wiring.

Why Choose 14/2 NM-B Copper Building Wire?

This 2-conductor (with ground) configuration is designed for maximum ease of use in dry-location residential applications. The Type NM-B construction allows for direct routing through wooden framing members without the need for conduit, while the solid annealed copper ensures minimal voltage drop and superior electrical efficiency for standard household loads.

• Classic White Color Coding: The white PVC jacket serves as the universal visual indicator for 14 AWG circuits, ensuring code compliance and simplifying circuit management for installers and inspectors.

• High-Purity Copper Conductors: Soft-drawn copper provides excellent electrical throughput and remains flexible enough for easy termination in standard switch and outlet boxes.

• Streamlined Rough-In Geometry: The flat, low-friction jacket is optimized to glide through bored studs and joists, significantly reducing the physical effort required during the wiring phase.

• Advanced Insulation Shielding: Individual conductors are protected with heat-resistant PVC and a smooth nylon outer layer (THHN/THWN-2) to resist nicks and abrasions during installation.
