Building Cable
- 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.
Wire
- Use for panel and equipment (hook-up)
- Stranded Wire: Flexible
Solid Wire: Bend and Stay - Temperature Range: -40° to 220° F
- Insulation: PVC Plastic
Also known as hook-up wire, this wire is primarily used for wiring electrical panels, lighting, and plant floor equipment. It meets UL 1007, UL 1015, or UL 1569 for appliance wiring.
Stranded wire is flexible, so it’s pliable enough to be pulled around corners. The strand count is the number of strands followed by the size of the individual strand. The higher the number of strands, the more flexible the wire.
Solid wire bends and stays in the position that you bend it. It’s easier to terminate than stranded wire.
Flame rated VW-1 wire meets requirements for preventing the spread of flames based on a timed test with vertically suspended material.
