About this document

American Wire Gauge Table and AWG Electrical Current Load Limits is a document available to read on EtoBox.

American Wire Gauge (AWG) diameters can be calculated by applying the formula D(AWG)=.005 92((36-AWG) / 39) inch. In the Metric Gauge scale, the gauge is 10 times the diameter in millimeters, so a 50 gauge metric wire would be 5 mm in diameter. The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule.
