The AWG system does not include the insulation size in the diameter dimensions.Ĭaption: cross-sectional wire area Importance of American Wire GaugeĪs the wire’s cross-section area increases, the wire’s resistance decreases. Several other countries use international metric standards where wire cross-section is represented in square millimeters, as mentioned in International Electrotechnical Commission 60228. The AWG system is similar to the Standard Wire Gauge system used in Britain. Before this standard, manufacturers used different methods to measure very confusing wire. The AWG system came into existence in the year 1857. They are for solid, round, conductive, and single-stranded electrical wires. You can also call it the Brown & Sharpe wire gauge or just the wire gauge. The smallest standard size in AWG is 40 AWG, and the largest is 0000. In this system, as the AWG number increases, the wire diameter and thickness become smaller. In North America, AWG is the standardized wire gauge system denoting the wire sizes. How? Let’s learn how the gauge affects the different technical specifications of the wire and have the AWG Wire Size Chart in detail. Wire diameter or gauge is the most crucial among so many different features. Thus, you must pick the correct type of wire for a particular application.
Also, they have a considerable role in maintaining safety in wiring. It would help if you had wires and cables for all types of electrical systems as they make the system function.
