American Wire Gauge (AWG)

American Wire Gauge (AWG) is a standardized system used to measure the diameter of electrical wires. The scale assigns smaller numbers to thicker wires and larger numbers to thinner ones. For example, a smaller AWG number like 10 indicates a thicker wire capable of carrying more current, while a larger number like 20 indicates a thinner wire suitable for less current. This system helps electricians and engineers select the appropriate wire size to ensure safety and efficiency in electrical systems. AWG provides a reliable way to specify wire dimensions universally across the industry.
