Note:

  • American wire gauge (AWG), also known as the Brown & Sharpe (B & S) wire gauge, is a standardized wire gauge system used since 1857 predominantly in North America for the diameters of electrically conducting wire.
  • In the North American electrical industry, conductors larger than (4/0) or (0000) AWG are generally identified by the area in thousands of circular mils (kcmil), where 1 kcmil = 0.5067 mm2. The next wire size larger than (4/0) or (0000) has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area of a circle with 1000 mil (1 inch) diameter. An older abbreviation for one thousand circular mils is MCM.
