About Wire and Cable

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.

Wire with a cross-linked polyolefin (XLPO) insulation is ultra-flexible and withstands high heat, making it suitable for applications such as vehicle engine wiring.

SAE wire meets standards for low-voltage wiring in vehicle electrical systems.

Outdoor Wire

The EPDM insulation on this wire won’t become brittle or crack from sunlight, humidity, rain, temperature changes, abrasion from dirt and debris, and other rough outdoor conditions. It meets Mine Safety and Health Administration (MSHA) standards for material quality.

SC wire is a good choice for temporary setups powering outdoor lights, equipment, generators, and power distribution boxes, since its thick insulation makes it easy to move and reuse. Commonly found at outdoor events, it’s also known as stage cable.

DLO wire carries higher voltages than SC wire, making it the better choice for heavy duty applications. Use it to run power to motors, cranes, and other equipment in shipyards, mines, and oil- and gas-drilling rigs. Also known as diesel locomotive cable, this wire was originally designed to wire trains. An inner layer of chlorinated polyethylene plastic (CPE) gives it increased resistance to chemicals, heat, and flames. It’s also rated RHW-2, so it can be used underground and in wet locations.

All are flame rated, so they meets requirements for preventing the spread of flames based on a timed test. FT4 wire is mounted to a vertical tray during testing. FT5 wire is suspended horizontally during testing.

High-Current Pin-and-Sleeve Cords

Send power from generators to keep the lights on and equipment running. These cords are often used to convey temporary power during outages or at trade shows and mobile job sites. Able to send currents above 250A, they’re commonly connected to power distribution panels and transfer switches. Push and twist to lock them in place, where they remain secure against high current loads, vibration, and pulling. They don’t require tools to connect or disconnect, making them convenient for short-term setups.

For outdoor use, these cords are rated NEMA 3R for protection from rain, snow, and sleet. They also resist sunlight, oil, and chemicals.
