What is American Wire Gauge (AWG)

AWG, or American Wire Gauge, is a standardized system used in the PCB industry to measure the size of wires. It assigns a specific number to each wire size, with smaller numbers indicating larger wire sizes. The gauge of a wire is crucial as it determines the wire’s current-carrying capacity. Thicker wires, denoted by a lower AWG number, can handle more current.
