In the AWG system, what does a larger number denote regarding wire size?

In the American Wire Gauge (AWG) system, a larger number indicates a smaller wire size. This system is a standardized measure used primarily in the United States to specify the diameters of electrically conductive wires. As the gauge number increases, the actual diameter of the wire decreases.

For example, a wire labeled as 10 AWG is significantly thicker than a wire labeled as 20 AWG. This inverse relationship means that higher numbered gauges correspond to thinner wires, which can affect various electrical characteristics, including resistance and current-carrying capacity. Understanding this sizing system is essential for proper material selection in installations to ensure efficiency and safety.
