The smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire. The size of the wire dictates how much current can safely pass ...

It’s measured in AWG (American Wire Gauge), and the lower the number, the thicker the wire. For shorter runs under 50 feet, ...
