American Wire Gauge (AWG) is a U.S. standard set of non-ferrous wire conductor sizes. The gauge means the diameter.
AWG stands for American Wire Gauge, and it is a standard used for denoting wire conductor diameter. The system is counter-intuitive, so the lower the AWG, the thicker the conductor.Actually the system is even more counter-intuitive than that. Once you get to wires thicker than 0 AWG, you do not use negative numbers.
