  • What does gauge mean in electrical wiring?

  • The gauge also determines the resistance of the wire and its weight per unit of length. When dealing with wire gauge, the characteristics of a wire usually specified on a chart is the wire’s size (specified in AWG), diameter, area, feet per pound, ohms per 1000ft, and current capacity (in amps). Below is a chart of different wire gauges.

  • What is the size of a 1 gauge wire?

  • 1 gauge wire is the first 鈥榥on-negative or 0鈥?wire gauge. 1 gauge wire diameter is 7.348 mm and it has a 42.4 mm2 (1 AWG to mm2) cross-section or area. Given the 42.4 mm2 thickness, the 1 AWG copper wire has a current-carrying ampacity of 130 amps at 75C.

  • 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.

  • How many amps can a wire gauge handle?

  • Wire Gauge Size Chart. American Wire Gauge standards range from 0000 (which can handle up to 302 amps) to 40 (which can handle up to 0.0137 amps). Most household and commercial wiring demands range from 2 (95 amp maximum) or 3 (85 amp maximum) to 14 (15 amp maximum).
