Stranded Wire Properties

Published in Conductors

The American Wire Gauge (AWG) is formed by designing size #36 to the .0050in. diameter and #1000 (4/0) to the .4600in. diameter. The intermediate diameters are formed by a geometric progression. Since there are 39 intermediate sizes, the ratio of the diameters of consecutive sizes given by the equation:

\[\sqrt[{39}]{{\frac{{0.4600}}{{0.0050}}}} = \sqrt[{39}]{{92}} = 1.12293\]

The square of this ratio is 1.2610. Since the cross-sectional area, weight and DCR (Direct Current Resistance) vary with the square of the diameter, the values for any size can be determined by multiplying or dividing the adjacent values by 1.2610.
