AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors.
The higher the AWG number is, the smaller the wire diameter is.
AWG is American standard that defines the cross-sectional areas and diameters for solid, round electrical wire and is based on the number of dies required to draw down the raw copper to the appropriate size.
