AWG Table – American Strand Design
In the North American economic area, the dimensions of copper conductors for high voltage and telecommunications purposes are usually given in AWG numbers*. In Germany, Europe and many other parts of the world, we speak of metric cross-sections in mm².
AWG means American Wire Gauge and represents the actual cable cross-section in mm² & conductor resistance. HEW uses the list below for this purpose. This is also available for download.
