To designate larger diameters, (since there is no number smaller than 1) the next logical number was 0, or "one aught", .325", then 00, generally designated 2/0, two aught, .365", then 000, threee aught, .410, and 0000, 4/0, four aught.

The designation AWG refers to American Wire Gauge. AWG wire is described by it's Circular Mil area and the number of strands for each size wire depending on wire type used.

AWG #2 has a CM Area of 66,360 while AWG 2/0 has a CM Area of 133,100.

That's good stuff..thanks for the explanation...can you define/elaborate on Circular Mil Area...
