Barker Awg In 60228 Canena 0405

  1. 1. AWG/kcmil size wire and cables in IEC 60228 <ul><li>CANENA </li></ul><ul><li>March , 2005 </li></ul>
  2. 2. History <ul><li>July 2002- Mr. Ron Lai introduced a NWIP proposal to US IEC TC 20 TAG to add AWG/kcmil in IEC 60228, the basic std. for power cables. </li></ul><ul><li>TC 20 TAG approved the project </li></ul><ul><li>Potential benefit: “developing countries” markets: China, India, Brazil, Chile, etc. </li></ul>
  3. 3. History <ul><li>An international ad-hoc Task Force (Canada, Mexico and US industry and NRTLs) was set up by NEMA to hammer technical and tactical details. </li></ul><ul><li>Liaisoning : IEEE, UL, ICEA, ASTM, CSA, ANCE, USNC, CSC, etc. </li></ul><ul><li>ASTM tables were aligned with IEC 60228 </li></ul>
  4. 4. History <ul><li>Submittal options: </li></ul><ul><ul><li>“ in some countries” clause to get the tables in the printed standard and then negotiate an EDR </li></ul></ul><ul><ul><li>Annex E of Part 2 IEC directives - size . Not sure how powerful a tool this could be. </li></ul></ul><ul><ul><li>EDR request. Not acceptable in the CDV phase, need to wait the maintenance cycle. New and unknown tool. </li></ul></ul>
  5. 5. History <ul><li>Tactical option considered </li></ul><ul><ul><li>Create a CANENA “60228” and get IEC to refer to it as a normative reference. Not clear if possible since IEC 60228 exists already and the CANENA – IEC agreement targets CANENA areas not covered by IEC. Time was also a factor. </li></ul></ul>
  6. 6. History <ul><li>At CDV stage: </li></ul><ul><ul><li>Mexico and US voted negative with the AWG system proposal as comment </li></ul></ul><ul><ul><li>Canada vote affirmative with “in certain countries” request </li></ul></ul>
  7. 7. History <ul><li>CDV ballot was successful. 2 negative votes </li></ul><ul><li>N. American countries comments were noted but not really addressed. </li></ul><ul><li>Canada’s request initially not even noted. After negotiations a note was included in the Foreword with a small conversion table </li></ul>
  8. 8. History <ul><li>FDIS ballot </li></ul><ul><ul><li>All North American countries voted again negative </li></ul></ul><ul><ul><li>Ballot passed (only 3 negative votes) </li></ul></ul><ul><ul><li>Maintenance phase established for 2010 </li></ul></ul>
  9. 9. History <ul><li>TC 20 meeting, Berlin Nov.2004 </li></ul><ul><ul><li>Two documents essentially raising barriers for AWG inclusion were presented. </li></ul></ul><ul><ul><li>A “study group” was established to discuss the two documents. It is chaired by the most vocal opponent of the proposal. </li></ul></ul>
  10. 10. Future actions <ul><li>Submit the EDR and support it at all levels </li></ul><ul><li>Learn form previous EDR submittals: </li></ul><ul><ul><li>Define “infrastructure” linked to AWG sizing system </li></ul></ul><ul><ul><li>Support “relevant market share” argument with data </li></ul></ul><ul><ul><li>Ensure the ballot limits the voting options to those defined by the EDR policy </li></ul></ul><ul><ul><li>Try to find allies before the vote </li></ul></ul><ul><ul><li>Keep SMB informed </li></ul></ul>
  11. 11. Major issues <ul><li>“Limited market size” (30% of world market in over 60 countries!) </li></ul><ul><li>Long term commitment towards a single metric system </li></ul><ul><li>IEC 60228 is a fundamental building block for all insulated cables, connectors, wiring devices, boxes, current protection devices. Inclusion of AWG could affect all. </li></ul>
  12. 12. Role of CANENA <ul><li>? </li></ul>
