About Wire and Cable

Use for buildings
Stranded Wire: Flexible
Solid Wire: Bend and Stay
Temperature Range:
Wire with Nylon Outer Insulation: -10° to 190° F
Wire with Polyethylene Outer Insulation: -40° to 190° F

Install this wire in conduit and cable trays in commercial and industrial buildings. It's also known as branch circuit wire.

Stranded wire is flexible, so it’s pliable enough to be pulled around corners. Solid wire bends and stays in the position that you bend it. It’s easier to terminate than stranded wire.

Wire with a nylon outer insulation resists oil and water. Wire with a polyethylene outer insulation resists abrasion and chemicals. It’s more flexible than nylon insulated wire.

TFFN wire is also known as fixture wire. It’s for use in dry locations. XHHW-2 wire is for dry and wet locations where wire may be exposed to dripping or splashing liquid. THHN wire can be used in dry or damp locations where wire is exposed to condensation or moisture, such as a basement. THWN and THWN-2 wire can be used in both wet and dry environments.

Flame rated VW-1 wire meets requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Abrasion-Resistant Wire

Use for panel and equipment (hook-up)
Wire with FEP Plastic Insulation: Flexible
Wire with Silicone Rubber Insulation: Ultra Flexible
Temperature Range:
Wire with FEP Plastic Insulation: -90° to 390° F
Wire with Silicone Rubber Insulation: -40° to 300° F

A thick insulation withstands abrasion, so this wire can be used over rough surfaces. It’s also known as hook-up wire.

Wire with silicone rubber insulation is ultra-flexible for use in applications that require tight turns. It also withstands moisture.

Flame rated wire meets requirements for preventing the spread of flames based on a timed test; VW-1 wire is suspended vertically during testing, and FT2 wire is suspended horizontally during testing.
