What circuits is 10/2 NM-B used for?

It feeds 30-amp, 240-volt loads such as electric dryers, ranges, water heaters and small subpanels. It is also used for 120-volt circuits that need 10-gauge wire for voltage drop.

Can it be used outdoors or underground?

No. NM-B is rated for dry, indoor locations only. Outdoors or underground you need UF cable or conductors in conduit.

Does it include a ground wire?

Yes. It has two insulated 10-gauge conductors plus one bare copper ground, so it wires a 120/240-volt circuit with ground.

What amperage can it carry?

Terminations limit it to the 60°C column, which is 30 amps for 10-gauge copper. Do not treat the 90°C conductor rating as the circuit rating.

How does it differ from 10/3 NM-B?

10/3 adds a third insulated conductor, needed for circuits that require a neutral plus two hots, such as some dryers and ranges. 10/2 gives you two hots and a ground.

Can it be run in conduit?

It can pass through short conduit sleeves for protection, but it is not designed to be pulled through long conduit runs. Use THHN for that.

What reviewers say

Electricians and DIYers treat 10/2 NM-B as a commodity and judge it by how it handles and pulls. Most say the jacket strips cleanly and the cable feeds through studs without kinking. Complaints center on stiffness of the solid 10-gauge conductors and on jacket damage when staples are driven too hard.

What people mention

JacketPraisedOwners say the PVC jacket strips cleanly and resists nicks during pulls.
FlexibilityMixedThe cable unrolls easily, but the solid 10-gauge conductors are stiff in tight boxes.
BuildPraisedBuyers describe solid copper and a tough nylon wrap that holds up to abrasion.
StaplingCriticisedReviewers report the jacket crushing or tearing when staples are driven too hard.

About the Cerrowire 10/2 NM-B Cable with Ground

This is 10 AWG, 2-conductor Type NM-B nonmetallic sheathed building cable with a bare copper ground conductor. It is made for enclosed, interior wiring in normally dry locations. It can power outlets, lighting and appliances in residential and commercial settings.

The conductors are solid copper with PVC insulation, rated THHN at 90°C and 600 V. A nylon jacket protects the conductors and inner insulation against abrasion and chemicals, and stays flexible across a broad temperature range. The PVC outer jacket is rated at 75°C and protects against heat, moisture, oils and similar chemicals.

The cable is lighter than metal-clad building cable, and the pliable sheathing makes it easier to unspool, straighten and handle. It can be used for new or replacement wiring, exposed or concealed, in dwellings up to three floors above grade. It can be fished through walls, ceilings and masonry blocks. The amp rating is limited to that of 60°C rated conductors under National Electrical Code Article 336. The cable is UL listed.
