NM-B 6/3 Wire with Ground 10ft - Heavy Duty 6 AWG Residential Cable

In this review of the NM-B 6/3 Wire with Ground 10ft, the bottom line is simple: this is a heavy-duty, UL listed 6 AWG NM-B cable built for indoor residential branch circuits where robust copper conductors matter. The reviewer found it most useful for fixed installations that require two hots, a neutral and a ground, such as 240V circuits, subpanels, or EV charger branch runs. Its construction and temperature rating make it reliable for dry indoor work, and the stranded copper and PVC jacket make pulling and terminating easier than solid alternatives.

Key Features

• UL Listed NM-B: The UL listing confirms this cable meets recognized safety standards for indoor residential wiring and gives confidence when used in dry locations.
• 6 Gauge, 3 Conductors with Ground: The 6 AWG stranded copper conductors provide low resistance and are suited to higher current branch circuits like ranges, dryers and EV charger feeds.
• 600V and -10C to +90C Rating: A broad voltage and temperature range makes the cable suitable for typical home electrical environments without derating in normal dry conditions.
• Oxygen Free Copper: High-purity copper reduces resistive losses and improves long-term conductivity compared with lower-grade conductors.
• PVC Jacket and Nylon Coating: The double-coated inner conductors and robust PVC sheath improve corrosion resistance and make pulling and stripping easier during installation.
• Indoor Dry Use: Designed for exposed or concealed installations in normally dry locations such as basements and garages when protection from moisture is ensured.

Who It's For

This cable is best for electricians, contractors and experienced DIYers who need a reliable 6 AWG 6/3 NM-B run for fixed residential circuits - think subpanels, 240V appliance circuits, EV charger branch cabling, and heavy-duty HVAC feeds. Its stranded copper and manageable jacket make it practical for pulling through walls, cavities and conduit where permitted.

It is not intended for portable cord use, outdoor, wet or continuously damp environments; anyone needing direct burial, outdoor-rated or wet-location cable should look for appropriately rated alternatives rather than this NM-B product.

Pros & Cons

Pros

• High-quality oxygen free copper delivers excellent conductivity and lower resistance for heavy loads.
• UL Listed and RoHS compliant, providing assurance on safety and material standards.
• Stiff but manageable PVC jacket and nylon-coated conductors help with pulling and termination.
• Versatile for many residential fixed circuits including 240V applications and subpanels.

Cons

• Not rated for outdoor, wet or damp locations, limiting use to dry indoor installations only.
• The cable is heavy and not flexible enough for portable or tight-bend applications.

Our Verdict

The NM-B 6/3 Wire with Ground is a solid choice for anyone installing fixed residential 240V or heavy branch circuits who needs dependable 6 AWG conductivity and UL listing. It delivers good value through quality copper conductors and a pull-friendly jacket, but should be limited to dry, indoor use; for outdoor or wet installations a different rated cable is required.

Frequently Asked Questions

Can this cable be used for an EV charger branch circuit?
This cable is suitable for indoor fixed branch circuits for EV chargers when the installation is inside and follows local code; confirm ampacity and breaker sizing with local regulations.

Is the cable rated for outdoor or wet locations?
No. The NM-B 6/3 is intended for dry, indoor use only and is not rated for outdoor, wet or direct burial applications.

Is the ground conductor full size?
The cable includes a ground and the package notes a ground wire compatible with the 6/3 NM-B configuration; verify local code for grounding conductor sizing requirements.
