Our take on the NM-B 6/2 Wire With Ground 25ft 6awg Copper 6 Gauge 2 Conductor

This is a 25-foot coil of 6-gauge, 2-conductor NM-B (non-metallic sheathed) copper cable with a bare ground wire, sold as one length. NM-B is the standard indoor branch-circuit cable used for high-amperage runs such as ranges, dryers, subpanels and EV chargers. The 6 AWG copper conductors support up to 55A at 60°C per the NEC, so it is typically paired with a 50A breaker. It is a commodity item, so price varies mostly by copper content and length; compare per-foot cost across stores before buying.

Questions and answers

Is 6/2 NM-B enough for a 50A range or EV charger?
Yes for many 50A circuits. The 60°C ampacity of 6 AWG copper is 55A, and NM-B is limited to the 60°C column, so a 50A breaker is the usual match. Check your local code and the appliance's nameplate before committing.
Can this cable be buried or run outdoors?
No. NM-B is for dry, indoor locations. For underground or wet areas use UF-B or conduit with THWN conductors.
What is the difference between 6/2 and 6/3?
6/2 has two current-carrying conductors plus ground. 6/3 adds a third conductor, which you need for circuits requiring a neutral, such as some dryers and subpanels.
Does it come with a ground wire?
Yes. This is 6/2 with ground, so a bare copper equipment ground is included alongside the two insulated conductors.
How many amps can 6-gauge copper carry?
At 60°C, as required for NM-B, 6 AWG copper is rated 55A. Many installs use a 50A breaker; higher ratings require a wiring method rated for 75°C.
When is the best time to buy?
Copper cable tracks metal prices, so watch for sales and compare per-foot cost. Buying a longer coil and cutting to length is often cheaper than several short lengths.
