Our take on the Romex SIMpull 8/2 NM-B Copper Building Wire 125 ft Black Jacket

Romex SIMpull 8/2 NM-B is a 125 ft roll of two-conductor copper building wire with a 10 AWG ground, rated 40A at 90°C and 600V for residential branch circuits. The SIMpull jacket is designed to pull through conduit and studs with less lubricant and friction than older NM-B jackets. It is commonly used for 40A appliances such as ranges, cooktops and larger water heaters. The best new price is $170.00 at Home Depot as of November 3, 2026, and it is the only new listing tracked, so there is no recent price range to compare against.

Pros
  • Stranded 8 AWG copper is easier to bend and pull than solid
  • SIMpull jacket reduces pulling friction
  • Includes a 10 AWG ground conductor
  • 90°C insulation and 600V rating
  • UL listed and RoHS compliant
Cons
  • Only 125 ft, so long runs need a splice or a second roll
  • NM-B is for dry indoor locations, not conduit outdoors or in wet areas
  • 8/2 has no neutral, so it will not serve 120/240V appliances needing one
  • One store listing means little price competition

What reviewers say

Owners of SIMpull NM-B generally report that the jacket pulls more easily than standard NM-B and that the stranded conductors are easier to work with in boxes and panels. Complaints tend to focus on jacket stiffness in cold weather and on price per foot.

Pros
  • Smoother pulling through studs and conduit
  • Stranded conductors bend easily
  • Clear jacket markings for gauge and rating
Cons
  • Stiff and hard to handle in cold weather
  • Costs more per foot than basic NM-B
  • Jacket can scuff on sharp framing edges

Questions and answers

Is 8/2 NM-B enough for a 40A range?
Yes for many 40A ranges, since 8 AWG copper is rated 40A at 60°C and 55A at 90°C. Check the appliance nameplate and local code, because some ranges need a neutral and require 8/3.
Does 8/2 include a ground wire?
Yes. It has two 8 AWG conductors plus a 10 AWG ground, which is the standard NM-B configuration.
Can I run this outdoors or underground?
No. NM-B is for dry, indoor locations and must not be buried or run in wet areas. Use UF or THWN for outdoor and underground runs.
How many amps can 8 AWG carry here?
The cable is rated 40A for typical 60°C terminations and up to 55A ampacity at 90°C. Breaker and terminal ratings usually limit the circuit to 40A.
Is 125 ft enough for my run?
Measure the path including vertical drops and slack. If the run exceeds 125 ft, buy a longer roll rather than splicing inside a wall.
When is the price lowest?
Wire prices track copper, so they move with metal markets rather than seasonal sales. At $170.00 at Home Depot as of November 3, 2026, compare per-foot cost against other gauges and lengths before buying.
