About Wire and Cable

NM-B

Use For:
NM-B, THHN: Buildings
UF-B, THHN: Buildings, Outdoors
Bend and Stay
Temperature Range: 10° to 190° F
Insulation: PVC Plastic

Rated for in-wall installation, this cable carries power to wall outlets. Also known as branch circuit wire, it can be used without conduit. It has solid THHN building wires, so the cable will stay in the shape you bend it. The uninsulated ground wire is not counted in the number of wires.

NM-B cable is for dry locations where moisture is not a concern, and often run through walls, ceilings, and concrete blocks.
