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. Wire with a nylon outer insulation resists oil and water. 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.

600V AC/DC: Ultra Flexible
Temperature Range: -40° to 190° F

Connect batteries in vehicles and generators.

Strand count is the number of strands followed by the size of the individual strand.

Wire with a PVC plastic insulation resists fuel and oil.

Wire with an EPDM rubber insulation is ultra-flexible for use in applications that require tight turns. The insulation resists abrasion and oil.

SAE J1128 and SAE J1127 wire meet standards for low-voltage wiring in vehicle electrical systems.

Outdoor Wire

Use for outdoors, buildings, power supply
Flexible
Temperature Range: -55° to 220° F
Insulation: EPDM Rubber

Protected by an EPDM insulation that resists UV light, water, abrasion, and oil, this wire is often used outdoors in lighting and generators. It’s flame rated FT5 to meet requirements for preventing the spread of flames based on a timed test with material that is horizontally suspended and heated before being exposed to flame.

Oil-Resistant Continuous-Flex Cable

This cable has an insulation with excellent resistance to oil, so it can be used near motors and equipment that require oil lubrication. Often used in automated applications such as robotics and cable carriers, it withstands continuous motion without degrading data or signal transmission. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Shielded cable has a layer of braid that blocks signal interference from nearby equipment and devices.

Bend radius is the point to which the cable will bend without being damaged. It is measured from the center of the bend to the edge of the cable. The smaller the measurement, the tighter the bend.

Welding Cable

Use For: Welding
600V AC: Bend and Stay
600V AC/DC: Flexible
Temperature Range: -55° to 220° F
Insulation: EPDM Rubber

This cable withstands abrasion, oil, and the rough conditions found in welding applications. It’s flame rated VW-1 to meet requirements for vertical flame testing.

Class K cable is for general purpose welding applications. It bends and stays in the position that you bend it.

Class M cable is more flexible and durable than Class K cable.

Battery Power Cords

Connect batteries to each other.

Clamp × lug and lug × lug cords also connect batteries to electrical systems.

Cords with post terminals or stud terminals connect two or three batteries in parallel for maximum starting power. Connect the positive terminals together and the negative terminals together to get the combined capacity (in amp-hours) of the batteries—battery voltage remains the same.
