Southwire 63946926 Romex SIMpull NM-B Cable, Blue Jacket, 14-3 with Ground, 600V, 15 ft

Overview

Southwire’s 63946926 Romex NM-B cable delivers a practical solution for residential wiring with a blue SIMpull jacket. The 14-3 with ground assembly uses three solid copper conductors and a bare ground, all wrapped in PVC insulation and a durable nylon sheath. At 15 feet, the coil is designed for handy runs through dry indoor spaces, making it a versatile option for branch circuits connecting outlets and switches.

Why choose SIMpull NM-B for this application

SIMpull Technology reduces friction during pulling, helping you navigate tight conduits and wall cavities more smoothly. The blue jacket aids handling and visibility on the jobsite, while the solid copper conductors provide low-resistance paths for typical household loads. The included bare ground supports proper grounding practices when installed in compliant residential circuits.

• Enhanced pullability through walls and conduits, saving time on install.
• Color-coded 14 AWG conductors with a durable nylon/ PVC construction.
