Wire gauge

Wire gauge refers to the thickness or diameter of a wire, typically measured using standardized numbers called gauges. A lower gauge number indicates a thicker wire, which can carry more current safely, while a higher gauge means a thinner wire, suitable for less current. The gauge helps determine the wire's capacity for electrical load and suitability for specific applications, ensuring safety and efficiency in electrical systems. Think of it as a sizing scale that helps you choose the right wire for your electrical needs.
