10/2 NM-B Wire with Ground 50FT 10 Gauge Non-Metallic Sheathed Cable

In this review the 10/2 NM-B wire with ground is evaluated for homeowners and electricians who need a dependable length of 10 gauge residential cable. The bottom line: this 50ft coil with pure copper conductor is best for interior branch circuits where NEC Type NM-B is required, offering solid conductivity and a robust dual-layer jacket for in-wall or conduit installations. It is a practical, cost-conscious choice when you need a long run of 10 AWG cable for outlets, dedicated appliance circuits, or subpanel feeds.

Key Features

• Premium Pure Copper Conductor: High-purity bare copper reduces power loss and maintains stable conductivity for heavier loads like tankless water heaters or large appliances.
• Durable PVC & Nylon Jacket: A flame-retardant PVC inner insulation plus an abrasion-resistant nylon outer jacket protects the cable from physical damage and chemicals during installation and in-wall service.
• Paper-Wrapped Ground Wire: The ground conductor is wrapped in kraft paper for easy identification and neat separation when terminating or running through studs.
• 600V and Wide Temperature Rating: Rated for 600V and -10C to 90C (14F to 194F), it provides reliable performance across a wide range of indoor residential conditions.
• NEC Type NM-B Compliance: Manufactured to meet National Electrical Code requirements for non-metallic sheathed cable used in dry interior branch wiring.

Who It's For

This cable is aimed at electricians, contractors, and experienced DIYers wiring interior branch circuits where a run of 10 AWG is called for, such as dedicated appliance circuits, outlets for high-draw devices, or subpanel feeds. Its 50ft length and solid copper conductors make it a convenient option for medium-length runs in single-family homes.

It is not intended for outdoor, direct burial, or wet location use; anyone needing highly flexible cable for frequent movement or installations requiring flexible conductors should consider alternate wire types. Also, beginners should follow local code and consider professional help for permanent in-wall wiring.

Pros & Cons

Pros

• High-quality pure copper conductors that provide low resistance and dependable performance under load.
• Durable dual-layer jacket offers improved protection during installation and in-wall service.
• Paper-wrapped ground simplifies identification and separation when terminating or routing the wire.

Cons

• Outer sheathing can be relatively stiff and somewhat difficult to work with when bending or fishing through studs, according to some users.

Our Verdict

For interior residential wiring that requires a reliable 10 AWG run, this 50ft NM-B cable is a sensible buy: it pairs genuine pure copper conductors with a robust PVC and nylon jacket and meets NEC guidance for dry locations. It represents good value for homeowners and electricians who need dependable performance for outlets, dedicated circuits, and appliance feeds, though installers should be prepared for a stiffer jacket when pulling or bending.

Frequently Asked Questions

Can this cable be used for a tankless water heater?
Yes, the 10 AWG pure copper conductors are suitable for many tankless water heater circuits when sized appropriately to the unit and local code; always verify ampacity and breaker sizing for the specific appliance.

Is this cable rated for outdoor burial or wet locations?
No, NM-B is intended for dry, interior branch wiring and is not rated for direct burial or wet locations; use appropriate outdoor-rated cable for those applications.

How easy is it to strip and work with the sheathing?
The inner insulation and paper-wrapped ground are straightforward, but some users find the nylon outer sheath relatively stiff and slightly harder to maneuver in tight runs.
