1. Page 244-245 of “Introduction to Electromagnetic Compatibility” by Clayton R. Paul. 2. Wire gauge is determined by the cross sectional area of either a solid conductor or the sum of stranded conductors. For instance, according to the table quoted above: 16AWG wire could be either a solid conductor with a diameter of 50.8 mils, or a stranded wire with a diameter of 59 mils (105 x 36AWG, or 26 x 30AWG) or 60 mils (7 x 24AWG). The table quoted above gives you the various diameters; you would have to calculate the cross sectional area yourself, taking into account skin effect at high frequencies. Hope this helps.

Does anyone know of an OFFICIAL source that identifies the current-carrying cross-sectional area for each size in the AWG system? I'm not looking for correlation to standard metric sizes (I know there isn't a 1:1 correlation) just the official area of the standard AWG sizes. 2. Since stranding type affects the outer diameter of the copper (excluding insulation), I've always avoided using metric diameter in favour of metric area (square mm), and I've always assumed that the official measure (e.g. in metric electrical codes around the world) uses square mm as well. Is that assumption right or are there codes that use diameter? Thanks, Jim Eichner, P.Eng.
