What is American Wire Gauge?
American Wire Gauge (AWG) is a numerical standard used in the United States to denote the diameter of round, solid, nonferrous, electrically conducting wire. The system assigns a number to each gauge, with smaller numbers indicating thicker wires and larger numbers representing thinner wires. For example, a 12 AWG wire is thicker and can carry more current than a 16 AWG wire.
In electrical applications, selecting the proper wire gauge is essential for safety and performance. Using wire that’s too thin for the electrical load can lead to overheating and potentially cause fires. Electricians rely on AWG standards to match wire size with circuit amperage and distance, ensuring efficient power delivery and reducing voltage drop. Common gauges used in homes include 14 AWG and 12 AWG for lighting and receptacles.
