  • What does AWG mean in electrical?

  • 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 is the smallest AWG size?

  • The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles. Note – WM Wire Gauge, US Steel Wire Gauge and Music Wire Gauge are different systems.
