What is AWG ?
The American Wire Gauge is a hierarchical measurement of the cross section of a cable: today there are 39 increments in use. This may come as a surprise - the larger the core section, the smaller the gauge. Astonishing? The method of manufacturing the copper strands may help us to understand; the smaller a core is, the greater the number of wire drawing operations required to form it. The figure that provides the cross-section according to AWG is, in a way, representative of the number of times the copper is drawn to be refined.
