D-Shaped 8 gauge booster cable wire has highly conductive, 100% copper stranding to maximize current transfer. This is an ideal product for use when a 2-conductor wire is needed in heavy-duty applications. The PVC insulation provides a durable barrier to protect against weathering, chemicals, and abrasion. Each wire includes a color0coded stripe for easy polarity identification. Each product has a voltage rate at 60 Volts or less with temperature rating from –40°C to 80°C, and meets both SAE J1128 specifications.
