Our take on the Cerrowire 8/2 NM-B with Ground Copper Electrical Wire

This is 50 feet of 8-gauge, two-conductor NM-B cable with a bare ground, rated 600 volts and 40 amps. The copper conductors are stranded rather than solid, which makes pulls through conduit and tight runs easier than stiff solid 8-gauge. It is aimed at heavy residential branch circuits such as ranges, dryers, subpanels and large appliance feeds, where 8-gauge is required. Against typical 12/2 and 14/2 NM-B, it carries far more current but costs much more per foot and is harder to bend. The jacket is rated for dry indoor locations only, so it cannot go underground, in wet areas or outdoors.

Questions and answers

What can I run on 8/2 NM-B?
It suits 40-amp circuits such as electric ranges, dryers and subpanel feeds, and other large 240-volt appliances. Check the appliance's nameplate and local code before sizing.
Is this wire solid or stranded?
The conductors are stranded copper, which is more flexible than solid 8-gauge and easier to pull through bends and conduit bodies.
Can I bury it or use it outdoors?
No. NM-B is rated for dry indoor locations only. Underground, wet and outdoor runs need a different cable type such as UF.
Does it include a ground wire?
Yes. It has two insulated conductors plus a bare copper ground, so it works for 240-volt circuits that need a ground.
Why is it rated 90°C but only 40 amps?
The insulation withstands 90°C, but ampacity is limited to the 60°C column, which caps this cable at 40 amps.
Is the brand always Cerrowire?
No. The cable may be Cerrowire or Southwire depending on your area, and both meet the same NM-B specification.
