http://www.ieee-pses.org/symposium http://www.emc2004.org/ -------------------------------------------------- Hi >From memory, I think you will find a wire size conversion table in the NFPA standard for machine tools (NFPA 79) which is roughly the equivalent to IEC/EN 60204-1. 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.
