Solid Conductor AWG Dimensions Chart
See below for AWG wire gauge diameters and cross-sectional areas for solid, round conductors, according to the ASTM B258 “Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors”
Please note that these values would not apply to stranded conductor cables. Reference specific manufacturer documentation for that information. Contact us if you need additional assistance.
