6/2 NM-B with Ground, Stranded Indoor Electrical Wire, 100 FT, Black — Open-Box, 16% Off

[6/2 NM-B Cable – 55A Heavy-Duty Building Wire]: This 6 AWG 2-conductor NM-B cable with ground is designed for high-amperage residential and commercial branch circuits. Use it for sub-panel feeders, EV charger installations, large air conditioning units, electric ranges, and other heavy-duty 240V loads. Stranded bare copper conductors ensure reliable power delivery for demanding electrical projects.

[Stranded Bare Copper – Superior Flexibility for 6 AWG]: Made with 100% stranded bare copper conductors (7 strands, Class B stranding) – not solid, not CCA. The stranded construction provides excellent conductivity and low resistance for efficient 55A power transmission while offering superior flexibility compared to solid wire – easier to route through panels, conduit, and tight spaces during installation.

[600V Rated with Durable PVC + Nylon Jacket]: Rated for 600V and 90°C (dry locations) – though ampacity is limited to 60°C per NEC for NM-B cable. The durable PVC insulation with nylon jacket prevents electrical leakage and accidental contact. The black jacket is standard for 6 AWG NM-B cable – there is no specific color code for 8 AWG and larger conductors, making black the industry norm.

[Built-in Ground Wire – Safety for High-Amperage Circuits]: Includes a 10 AWG bare copper ground wire for equipment grounding protection. NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. The 6/2 configuration is ideal for sub-panel feeders, EV charging stations, large HVAC units, and other high-power applications requiring 55A capacity.

[Indoor Dry Locations Only – 100 FT Ready to Install]: Rated for indoor, dry locations only. May be installed exposed or concealed in normally dry locations, run through air voids of masonry block or tile walls where not exposed to moisture. Not for outdoor, wet, or damp locations. Pre-cut to 100 FT – no waste, no leftovers.

This 6/2 NM-B cable is designed for high-amperage residential branch circuits – sub-panel feeders, EV charger installations, large air conditioning units, electric ranges, and other heavy-duty 240V loads. Made with stranded bare copper conductors and a durable PVC+nylon jacket, it delivers reliable power transmission for demanding home electrical projects.
