Standard 12-gauge 2-conductor cable (which also includes a ground wire, which isn't counted as a conductor) is identified on the sheathing as 12/2 cable, and if the cable includes a third conductor, which is needed for special applications such as three-way light switches, it's 12/3 cable.
Why is 50 amp wire better than 20 amp?
Every electrician knows that a 50-amp wire has to have a larger diameter than a 20-amp or 30-amp one, and it's a good thing because undersizing an electrical wire can start a fire. Amp is short for ampere, and it's a measure of electrical current, which is typically likened to a flow of negatively charged particles called electrons.
How do you measure wire size?
Electricians measure wire size by its gauge number, which is based on how many wires can pass through a hole of a given size. The fatter the wire, the fewer strands will pass through the hole, so smaller gauge numbers refer to fatter wires, and larger gauge numbers refer to thinner ones. In the American Wire Gauge (AWG) system, each gauge number corresponds to a particular cross-sectional diameter or area. For example, 14-gauge wire has a cross-sectional diameter of 1.63 mm and a cross-sectional area of 2.08 mm 2, while 10-gauge wire has a diameter of 2.59 mm and an area of 5.26 mm 2.
