Our take on the 125ft Roll 8/2 NM-B Gauge Indoor Electrical Black Copper Wire Ground C

This is a 125 ft coil of 8/2 NM-B (Romex-style) sheathed cable with ground, made by NSL. It carries two 8 AWG copper conductors plus a bare ground, rated 40 amps at 600 volts, with PVC insulation and a nylon jacket. It is built for branch circuits in residential and commercial walls, and its $302.00 price at Home Depot as of November 3, 2026 is the only new price tracked, so there is no recent range to compare against.

Pros
  • 40-amp ampacity suits high-draw appliances
  • 125 ft length covers long runs without splices
  • Copper conductors with a bare ground included
  • UL listed and RoHS compliant
  • Nylon-jacketed PVC resists moisture and abrasion
Cons
  • 8 AWG copper is stiff and hard to bend in tight boxes
  • Not for wet or buried locations despite the wet-rated listing
  • Only two conductors plus ground, so no separate neutral for 120/240 split loads
  • One store price means little room to comparison shop

Questions and answers

Is 8/2 NM-B the right wire for a 40-amp circuit?
Yes. 8 AWG copper in NM-B cable is rated 40 amps, which matches ranges, dryers and small subpanels. Confirm the breaker and load with a licensed electrician for your specific circuit.
Can this cable be buried or used outdoors?
No. NM-B is for dry indoor locations inside walls, ceilings and floors. Use UF cable for direct burial or wet locations.
What is the difference between 8/2 and 8/3?
8/2 has two insulated conductors plus a bare ground. 8/3 adds a third insulated conductor, which you need for circuits requiring a separate neutral, such as some dryers and ranges.
How much does 125 ft of 8/2 NM-B cost?
The best new price is $302.00 at Home Depot as of November 3, 2026. Only one store price is tracked, so check local stock and pickup options.
What is included in the box?
You get one 125 ft coil or spool of 8/2 NM-B cable with ground. Boxes, staples and connectors are not included.
Is this wire copper or aluminum?
It is solid copper, which conducts better and connects more reliably than aluminum at terminations.
