Table 13.2.2 (pg. 79-32) of NFPA 79 gives the cross sectional area of conductors from 22 AWG through 1000 kcmil. More detailed tables per wire types are also located in Chapter 9 of the 2002 NEC (Tables 5, 5A & 8 - pgs 70-622 - 70-625). Even though there is isn't a exact conversion, Table 3B of IEC 60950-1 gives a commonly used cross reference between AWG and mm2 mm2 - AWG 0,75 - 18 1,00 - 16 1,25 - 16 1,5 - 14 2,5 - 12 4 - 10 6 - 8 10 - 6 16 - 4 25 - 2 35 - 1 50 - 0 70 - 000 95 - 0000 120 - 250 kcmil 150 - 300 kcmil 185 - 400 kcmil 240 - 500 kcmil 300 - 600 kcmil Sincerely, Nick Momcilovic Product Safety QuadTech A Subsidiary of Quad/Graphics Sussex, Wisconsin USA +1 414 566 7915 tel +1 414 566 9576 fax [email protected] www.quadtechworld.com NOTICE: This message, and any attachments, may contain confidential information that is legally privileged and/or proprietary.

Please can someone check this out? Thanks John Allen ERA Technology Ltd From: Jim Eichner [mailto:[email protected]] Sent: 02 June 2004 20:41 To: 'EMC-PSTC - Forum' Subject: AWG vs metric http://www.ieee-pses.org/symposium http://www.emc2004.org/ I keep running into conflicting AWG to metric conversion tables, including some that talk about diameter instead of area, and it raises a couple of questions: 1. 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.
