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