What is 6/3 NM-B used for?

It feeds 240 V loads such as ranges, dryers and subpanels, and other heavy branch circuits in dry locations. It has three insulated conductors plus a bare ground.

Can it be used outdoors or in wet areas?

No. NM-B is rated for dry locations only, including exposed and concealed work and air voids in masonry where not wet or damp.

Is the wire solid or stranded?

The three 6 AWG current-carrying conductors are stranded copper. The bare ground is solid 10 AWG copper.

What is the SIMpull jacket?

It is Southwire's low-friction jacket formulation designed to reduce pulling effort through conduit and framing.

What comes in the box?

Three insulated 6 AWG copper conductors in black, red and white, plus one bare 10 AWG solid copper ground, all under one jacket.

What temperature and voltage is it rated for?

600 V, with conductors rated to 90°C, though ampacity is limited per code for the termination and circuit.

What reviewers say

4.7 / 581 ratings

Buyers rate it highly, with electricians and DIYers praising the stranded conductors and the SIMpull jacket for making pulls easier. Complaints are few and mostly about the stiffness of 6 gauge cable and the effort of stripping the sheath.

What people mention

Pulling easePraisedOwners say the SIMpull jacket slides through conduit and studs with less effort than standard NM-B.
Conductor flexibilityPraisedStranded 6 AWG is described as much easier to bend and fit into boxes than solid wire.
StiffnessMixedSome buyers note the cable is heavy and stiff to handle over long runs.
Jacket strippingCriticisedA few users say the outer sheath takes care and a sharp knife to strip cleanly.
Build qualityPraisedReviewers report consistent Southwire quality and correct color coding.
