    • AWG/kcmil size wire and cables in IEC 60228
      • CANENA
      • March , 2005
    • 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.
    • 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
    • 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.
    • 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.
    • History
      • At CDV stage:
        • Mexico and US voted negative with the AWG system proposal as comment
        • Canada vote affirmative with “in certain countries” request
    • 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
    • History
      • FDIS ballot
        • All North American countries voted again negative
        • Ballot passed (only 3 negative votes)
        • Maintenance phase established for 2010
    • 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.
    • 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
    • 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.
    • Role of CANENA
