XMK 50ft NM-B 8/3 Wire with Ground — 8 AWG Copper Indoor Wiring

XMK 50ft NM-B 8/3 Wire with Ground for Indoor Residential Wiring

Rugged and reliable, this 8/3 NM-B cable brings three current-carrying conductors plus a dedicated ground for home wiring projects. With a 600 volt rating and RoHS compliant materials, it is built to handle typical household loads while staying within safe limits.

The copper conductors deliver solid conductivity, while a double jacket of nylon and premium PVC guards against wear as it travels through walls, channels, and raceways. Rated for dry indoor use, it is suitable for spaces like garages, basements, and utility rooms where temperatures may fluctuate from -10 to 90 C.

Common Uses and Scenarios

• Branch circuits for outlets and switches in residential rooms
• 240V circuits for ranges, ovens, and dryers within code requirements
• Subpanel feeders up to 40 amps and connections to HVAC equipment
• Power for large tools, hot tubs, spas, and other fixed loads in dry locations

Durability and Easy Wiring

Made with 99.99% oxygen free copper, the 8 AWG conductors support lower resistance and stable power transmission. The inner three wires are insulated in black, white and red and wrapped in a tough nylon PVC jacket, offering corrosion resistance and long service life. The PVC jacket is designed to be stiff enough for pull through studs and walls, while remaining manageable during installation.

• High conductivity copper minimizes resistance and supports consistent performance
• Dual jacket construction provides abrasion and chemical resistance
• Jacket facilitates pulling and stripping during installation

Installation Notes

Dry indoor use only; avoid wet or damp locations. The NM-B 8/3 cable can be installed exposed or concealed in normally dry areas such as garages and basements and can be pulled through conduits or raceways as part of a fixed wiring plan.
