12 gauge wire diameter

Best answer


A 12 gauge low voltage wire has a diameter of roughly0.0808 inches (2.053 mm), whereas 14 AWG wire has a diameter of around 0.0641 inches (1.628 mm). It is thus 26 percent thicker and 59 percent larger in a cross-sectional area compared to 14 gauge wire.

  • How thick is 12 gauge wire?

  • 12 gauge wire is 2.053 mm thick. This is equal to 0.0808 inches. Because the diameter of 12 AWG wire is so close to 2 milimeter we also refer to it as a 鈥? mm wire鈥? If you compare the diameter of 12 AWG wire vs diameter of 14 AWG wire, you can see that 14 AWG has a 1.628 mm diameter.

  • How many spirals are in a 12 gauge wire?

  • All AWG wires are made out of smaller individual wires. These small wires are spiral throughout the wire or cable. For some applications, it鈥檚 useful to know how many spirals there are in a 12 AWG wire. 12 gauge wire has 12.4 turns of wire per inch, and 4.87 turns of wire per cm (centimeter).

  • What is the electrical resistance of a 12 gauge copper wire?

  • Electrical resistance is measured in Ohms (惟). Resistance of 12 AWG copper wire is 5.211 milliohms per meter (m惟/m). This translates to 1.588 milliohms per foot (m惟/ft). As far as resistance is concerned, copper wires are about 40% more efficient for transporting electricity than aluminum wires.

  • What is the difference between 12 gauge and 14 gauge low voltage wire?

  • A 12 gauge low voltage wire has a diameter of roughly 0.0808 inches (2.053 mm), whereas 14 AWG wire has a diameter of around 0.0641 inches (1.628 mm). It is thus 26 percent thicker and 59 percent larger in a cross-sectional area compared to 14 gauge wire.
