wire gauge sizing

Best answer


Wire gauges range from low numbers to high numbers,with smaller numbers referring to smaller diameters and larger numbers representing larger diameters. For example,AWG 4 is 0.2043 inchesin diameter,and AWG 40 is .0031 inches in diameter.

  • What is the size of American Wire Gauge?

  • American Wire Gauge Conductor Size Table. American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0).

  • What does gauge mean in electrical wiring?

  • A wire鈥檚 gauge also indicates the thickness of the conductor that electrons flow through. For optimum transmission, a wire鈥檚 conductor must be increased in order to reduce resistance. Wire gauge sizes are represented through numerical values, AWG 4/0 through AWG 40.

  • What is the difference between AWG and wire gauge?

  • The lower the number assigned to a wire the larger its diameter; the higher the number the smaller its diameter. AWG stands for American Wire Gauge. AWG is the numerical standard that established wire gauge sizes for measuring wire gauges in the United States.

  • Where can I find the wire gauge chart?

  • To see the latest wire gauge chart, you can see ASTM B258-18. You can also use AWG gauges to describe stranded wire. For a stranded wire, the AWG gauge is the sum of the cross-sectional areas of each strand.
