NM-B 6/2 Wire with Ground 50FT - Heavy-Duty 6 AWG Residential Cable

In this review of the NM-B 6/2 Wire with Ground 50FT, the bottom line is straightforward: this cable is best for homeowners and installers who need a robust, UL listed 6 AWG branch-circuit cable for indoor 240V or high-current circuits. The reviewer found the cable admirably sturdy and well suited to permanent residential wiring tasks such as EV charger circuits, subpanel feeders, and large appliance feeds, with the primary reason to buy being its combination of thick 6 AWG copper conductors, a 10 AWG equipment ground and a manageable PVC jacket that eases pulling through runs.

Key Features

• UL Listed 6/2 NM-B: Provides assurance of compliance and consistent performance for indoor residential wiring projects.
• 6 AWG copper conductors: Thick 6 gauge copper reduces resistance and supports up to a 55 amp current rating for demanding circuits.
• 10 AWG ground: A dedicated ground conductor adds safety for subpanels, EV chargers and heavy loads.
• Durable PVC jacket: A stiff yet manageable jacket makes pulling and stripping easier during installation in dry locations.
• Temperature and voltage ratings: Rated to 600 volts and -10C to +90C, allowing reliable service in normal indoor temperature ranges.
• Stranded, corrosion resistant copper: High-purity copper and nylon/PVC insulation resist oxidation for long-term conductivity.

Who It's For

This cable is aimed at electricians, contractors and capable DIYers running permanent indoor circuits that require 6 AWG copper, such as EV charger lines, 240V water heaters, HVAC feeds, or 50-60A subpanel connections. The cables UL listing and heavy copper conductors make it a practical choice when code-compliant, fixed wiring is needed.

It is not intended for portable extension cords or wet/damp locations; projects requiring flexible portable cable, outdoor burial, or wet-rated conductors should look for cables specifically rated for those conditions. If extreme flexibility is required, a different stranded portable cord is a better option.

Pros & Cons

Pros

• High-purity 6 AWG copper delivers low resistance and reliable power for heavy loads.
• UL listed NM-B construction provides confidence for indoor residential installations in dry locations.
• Stiff but manageable PVC jacket makes pulls through conduit or raceways simpler than ultra-rigid solid conductors.
• Customers report good quality and value for money, with successful EV charger installs mentioned.

Cons

• Not designed for wet or damp locations and not intended as a portable cord, limiting use to dry indoor applications.
• Because it is relatively stiff, it is less flexible for tight bends or installations requiring high cable pliability.

Specifications

Our Verdict

The NM-B 6/2 50FT cable is a strong, practical choice for residential indoor wiring that needs 6 AWG capacity; it balances heavy-duty copper conductors with a manageable PVC jacket and UL listing, making it good value for permanent circuits like EV chargers, subpanels and large appliances. Choose a different product for wet locations or applications requiring superior flexibility.

Frequently Asked Questions

Can this cable be used outdoors?
No. It is intended for dry, indoor locations and is not rated for wet or direct-burial use.

Is this cable suitable for EV charger runs?
Yes. The 6 AWG conductors and 10 AWG ground make it suitable for many 50-60A EV charger circuits when installed per code.

Can it be pulled through conduit?
Yes. The cable can be pulled through conduit or raceways, though its stiffness requires careful handling on tight bends.
