Wire Gauge Table
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). 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 - W&M Wire Gauge, US Steel Wire
Gauge and Music Wire Gauge are different systems.
American Wire Gauge (AWG) Sizes and Properties Chart / Table
Table 1 lists the AWG sizes for electrical cables / conductors. In addition to wire size, the table provides values load
(current) carrying capacity, resistance and skin effects. The resistances and skin depth noted are for copper conductors. A
detailed description of each conductor property is described below Table 1.
