About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Vehicle Cable

Also known as GPT cable, this cable is often used in low-voltage applications such as battery and vehicle wiring and radios. It has one red wire and one black wire to easily identify polarity. The wires can be pulled apart for installation.
