What is 6/3 NM-B cable used for?

It feeds high-draw 240-volt loads such as electric ranges, cooktops, wall ovens and subpanels. It has three insulated conductors plus a bare ground.

Can it be used outdoors or underground?

No. NM-B is rated for dry, indoor locations, typically inside walls, floors and ceilings. Use a wet-rated cable such as UF for outdoor or buried runs.

Does it come in factory packaging?

No. The length is cut from a 1000-foot master reel, so it arrives without the manufacturer's packaging.

How many wires are inside?

Three insulated conductors plus a bare ground. The 6/3 designation refers to the three current-carrying conductors.

Is 6-gauge wire hard to work with?

Yes, compared with 12 or 14 gauge. The thick copper is stiff, so plan generous box space and gentle bends.

Our take on the 6/3 NM-B x 10' Non-Metallic Sheathed Electrical Cable with Ground

This is 6-gauge, 3-conductor non-metallic sheathed cable with a ground wire, sold in a 10-foot cut length. It is the standard branch-circuit wire for high-draw appliances such as ranges, cooktops, wall ovens and subpanels. The heavy copper conductors and 6 AWG size put it well above common 12 and 14 gauge wiring, so it is built for 240-volt loads rather than outlets and lighting. It arrives as a bare cut from a master reel, without factory packaging.
