NM-B 6/3 Wire with Ground 35ft 6 AWG Copper Cable - Reliable

In this review the NM-B 6/3 Wire with Ground (35ft) is evaluated as a heavy-duty indoor wiring option for residential branch circuits. The bottom line: this cable is built for projects that need a robust 6 AWG copper feed and clear 2-hot plus neutral capacity, and it delivers reliable conductivity and ease of pull in dry locations. Installers and DIYers who need a UL Listed, stranded 6/3 NM-B cable for circuits like ranges, dryers, EV chargers, subpanels or 120V/240V loads will find its construction and temperature rating reassuring.

Key Features

• 6 AWG Copper Conductors: Oxygen free copper reduces resistance and provides strong electrical conductivity for heavy loads.
• 3 Conductors with Ground: The 2 hot wires plus neutral and a dedicated 10 AWG ground make it suitable for 120V/240V branch circuits and equipment grounding.
• UL Listed NM-B Cable: Classified for dry, indoor residential use which simplifies installation in walls, basements and garages.
• Temperature and Voltage Ratings: Rated to 600 volts and -10C to +90C so it handles typical household heating and load conditions.
• Durable Jacket and Insulation: Nylon and PVC double jackets on inner conductors plus a stiff yet manageable outer jacket make pulling and stripping straightforward.
• RoHS Environmental Grade: Meets environmental compliance expectations for modern installations.

Who It's For

Electricians, contractors and experienced DIYers running permanent indoor branch circuits will get the most from this NM-B 6/3 cable. It fits jobs that need a reliable 6 gauge feed, such as electric ranges, dryers, HVAC equipment, EV charger branch runs to a subpanel, and other 120V/240V loads that require two hots and a neutral.

Homeowners who need outdoor, wet-location wiring or a portable cord should look elsewhere, because this NM-B cable is specified for dry, indoor installation only and is not designed for continuous flex or outdoor exposure.

Pros & Cons

Pros

• High-quality oxygen free copper conductors deliver low resistance and reliable power transfer for heavy loads.
• UL Listed NM-B classification and clear temperature/voltage ratings simplify code-compliant residential installs in dry areas.
• Stiff but manageable PVC jacket and stranded conductors make pulling through walls or raceways easier than solid conductors.

Cons

• Not suitable for outdoor, wet or damp locations, so additional planning or conduit is required for exterior runs.

Frequently Asked Questions

Can this cable be used outdoors?
No. The NM-B cable is rated for dry, indoor locations only and should not be used in outdoor or wet environments without appropriate protection.

Is the ground conductor the same gauge as the hot conductors?
No. The ground conductor provided is 10 AWG while the hot and neutral conductors are 6 AWG per the product specifications.

Can it be used for EV charger circuits?
Yes. Customers have used 6/3 NM-B for EV charger branch circuits to a subpanel or appropriate breaker, provided the run is indoors and follows code requirements.
