XMK NM-B 14/2 Wire with Ground – 250ft Indoor 14 AWG Copper NMB Cable

XMK NM-B 14/2 with ground provides a dependable indoor power solution for residential wiring projects, from everyday lighting circuits to outlet runs. This 250-foot spool offers the flexibility you need for longer runs between panels and fixtures, helping you plan clean, concealed installations in walls, ceilings, and above-ground channels. The copper solid conductor paired with a grounding wire is designed to support steady current flow while aligning with common electrical practices for safety and reliability. The result is a cable that feels sturdy in hand and performs consistently under typical indoor conditions.

The 250 ft length minimizes the need for frequent splices, allowing you to route cables through studs, joists, and cavities with fewer joints. The combination of a robust dual jacket and high-purity copper contributes to dependable power transmission, while the overall build communicates a sense of durability suitable for everyday indoor use.
