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.

Originally designed to meet the quality standards of the auto industry, this wire withstands high temperatures, flames, and abrasion. Unlike other low-voltage wires, this wire meets strict SAE performance requirements. You'll often hear it referred to as primary wire in trucks, trailers, forklifts, and other vehicles.

In protected environments, such as vehicle interiors, GPT wire is the best choice.

For wiring exposed to weather and wear and tear, choose a wire with polyethylene insulation. For these applications, GXL wire is the standard choice, as it balances flexibility and abrasion-resistance. TXL wire has a thinner insulation, making it easy to maneuver in tight spaces. SXL wire has a thicker insulation and is the most durable. It can withstand repeated exposure to heat, dust, chemicals, and salt.

Connect batteries in generators, forklifts, and other vehicles in corrosive environments. Also known as marine wire, this copper wire is tin plated to resist corrosion from salt water, battery acid, and oil. Designed for boats, it's a good choice for use outdoors. The PVC insulation stands up to fuel and oil. Strand count is the number of strands followed by the size of the individual strand.
