American wire gauge size calculator and chart.

American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire.

Wire gauge is a measurement of wire diameter. This determines the amount of electric current the wire can safely carry, as well as its electrical resistance and weight. Wire gauges may be broadly divided into two groups, the empirical and the geometric.

2023年4月18日 · The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated ampacities are just a rule of thumb .

2024年8月12日 · A wire gauge chart lists the American Wire Gauge (AWG) sizes for electrical cables and converts them to inches and millimeters. Wire properties such as cross-sectional area, ampacity and resistance are also listed.

In these AWG gauge charts, most common gauge values show the different characteristics of wire such as its diameter, area, ampacity, resistance, current density, fusing current and temperature ratings etc.

2024年8月2日 · Wire gauge refers to the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

2024年9月4日 · The American Wire Gauge system defines standards for wire gauges to help ensure you know which size wire you’re working with. We’ll explain wire gauges, why they matter and show you an example of a wire gauge chart.
