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

It suits 30-amp, 240-volt circuits such as electric dryers, ranges, water heaters and small subpanels. Code limits its ampacity to the 60°C column, so don't treat the 90°C conductor rating as the circuit rating.

Can it be used outdoors or underground?

No. NM-B is for dry, enclosed interior wiring only. Use UF cable for direct burial and wet locations.

Does it include a ground wire?

Yes. It has two insulated conductors plus one bare copper ground.

Is 10/2 the same as 10/3?

No. 10/2 has two current-carrying conductors plus ground; 10/3 adds a third conductor for circuits needing a neutral, such as some dryer and range hookups.

Can it run in conduit?

It can be fished through short conduit sleeves indoors, but it is not rated for wet conduit or outdoor runs. Check local code before long conduit pulls.

What does SIMpull add?

The nylon SIMpull jacket reduces friction so the cable pulls and straightens more easily than standard NM-B.

What reviewers say

Electricians and DIYers rate this cable for easy pulling and clean stripping, and inspectors accept it readily. Complaints center on stiffness of the 10-gauge solid conductors and the dry-location limit.

What people mention

Pull easePraisedOwners say the SIMpull jacket feeds through studs and conduit with noticeably less friction.
StiffnessCriticisedThe 10-gauge solid conductors are hard to bend and route inside crowded boxes.
BuildPraisedBuyers describe solid copper, a tough jacket and clear markings as dependable.
Dry useMixedSome buyers are caught out by the dry-location-only rating and can't use it outdoors.
StrippingPraisedReviewers report the sheath strips cleanly without nicking the conductors.

About the Southwire 10/2 NM-B Romex SIMpull Electrical Wire with Ground

Southwire 10/2 NM-B Romex SIMpull is a Type NM-B nonmetallic sheathed building cable with two 10 AWG solid copper conductors and one bare copper ground. It is used for enclosed, interior wiring in normally dry locations only. It can power outlets, lighting, and appliances in residential and commercial applications.

The conductors have PVC insulation and are rated THHN at 90°C and 600 V. A nylon jacket protects the conductors and inner insulation against abrasion and chemicals, and it 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 cables, and the pliable sheathing makes it easier to unspool, straighten, and handle.

The cable 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 for 60°C rated conductors per National Electric Code Article 336. The cable is UL listed.
