When buying extension cords, thickness (also known as gauge) is a key factor to consider. Cable thickness must match the current handling capacity of these wires, which come in a variety of gauges. Extension wire gauges 10 and 12 are among the most common. But what are the differences between these two thickness ratings? This article will be based on that question.
If you are checking power cords, here are a few differences to keep in mind:
- An electrical cord of 10-gauge and one of 12-gauge differs primarily in thickness.
- The diameter of a 10-gauge wire is larger than that of a 12-gauge wire.
- The AWG thickness of solid 10-gauge wire is 2.588 millimeters or 0.1019 inches. Therefore, 10-gauge cables are 26% larger than 12-gauge cables.
- Copper wires are the only wires that differ in diameter between 10-gauge and 12-gauge extension cables. Insulation thickness is not taken into account.
With this information you can found that 10-gauge and 12-gauge extension cords differ fundamentally in their thickness. The thickness of a wire determines its capacity to handle current.
