6/2 Wire with Ground 50FT 6 Gauge NM-B Cable - Pure Copper Residential

In this review the 6/2 Wire with Ground 50FT NM-B cable is evaluated for homeowners, electricians and DIYers needing heavy-duty branch circuit wiring. The bottom line: it is a purpose-built, NEC-compliant residential cable that stands out for its pure copper conductors and robust dual-layer insulation, making it a solid choice when reliable current capacity and mechanical protection matter. For anyone wiring outlets, switches, or lighting in standard 120/240V home circuits who wants a 6 AWG conductor and an integral ground, this cable delivers the core features without extras.

Key Features

• Pure Copper Conductors: 6 AWG inner conductors provide efficient, low-resistance current flow for heavier branch circuits and motors.
• Integrated Ground: Includes a 10 AWG ground conductor wrapped in kraft paper to meet common residential grounding practices.
• Dual-Layer Insulation: Inner PVC plus an outer nylon jacket gives electrical isolation plus abrasion and chemical resistance for runs inside walls or conduits.
• Wide Temperature Range: Rated for installations down to -10C and continuous use up to 90C, suitable for attics and other high-heat spaces.
• 600V Rated NM-B: Designed for standard US residential branch circuits and rated for up to 600V in dry or damp locations.

Who It's For

This cable is aimed at residential electricians and experienced DIY homeowners installing heavy branch circuits for ranges, air handlers, large motors or subpanels where a 6 AWG conductor is required. Its NEC-compliant construction and integrated ground make it a convenient single-cable solution for typical indoor wiring runs.

It is not intended for direct burial, outdoor exposed runs, or applications where conduit fill rules require different cable types; professionals needing those use cases should select a cable specified for outdoor or burial service instead.

Pros & Cons

Pros

• High-conductivity 100% pure copper conductors reduce voltage drop on longer runs.
• Built-in 10 AWG ground simplifies installation compared with separate grounding conductors.
• Durable nylon jacket adds mechanical protection for routing through framing and conduits.
• Temperature and voltage ratings support typical residential attic and wall installations.

Cons

• Type NM-B is not suitable for direct burial or exposed outdoor applications, limiting use to dry or damp indoor locations.
• The cable is specialized for heavier circuits; it is overkill for light loads or general lighting circuits where smaller gauge wire is standard.
