AWG - American Wire Gauge and Circular Mils

American Wire Gauge - AWG - and circular mils

American Wire Gauge (AWG) is a U.S. standard set of wire conductor sizes. The "gauge" is related to the diameter of the wire.

The AWG standard includes copper, aluminum and other wire materials. Typical household copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire.

The Circular Mil - CM - is a unit of area used especially when denoting the cross-sectional size of a wire or cable.
