American Wire Gauge definition hardware, standard
(AWG, sometimes "Brown and Sharpe Wire Gauge") A U.S. standard
set of non-ferrous wire conductor sizes. Typical household 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. Thicker wire is better for long distances due to its lower resistance per unit length.
