  2. CANENA Annual General Meeting History in Brief Ron Lai J Richard Barker Sr. Director VP Industrial Standards FCI Burndy General Cable

  3. CANENA Annual General Meeting • 1968, IEC 228 issued, British wire sizes in annex. • 1970, UK adopts square millimeter wires, British annex removed. • 1971, pound sterling goes decimal. • 1995, UK goes metric. • 1995, imperial units now US traditional units.

  4. CANENA Annual General Meeting • Reimer Stubbe, retired chair of TC 20 electric cables, said: • “The work of harmonizing cables started in the 1960s.” • “North Americans were not interested.” • “We lost thirty years!”

  5. CANENA Annual General Meeting • Probable reasons for lack of participation: • In the 1970s, • Deep economic recession. • Double digit inflation. • Record unemployment. • Markets were protected by tariffs.

  6. CANENA Annual General Meeting • USNC SC23F connecting devices. • Early 1990s, NEMA connector section participates on TAG. • AWG in body of several standards: • 998-2-1 • 998-2-2 • 998-2-3 • 999-1 • Maybe others.

  7. CANENA Annual General Meeting • USNC SC23F connecting devices. • Late 1990s, IEC maintenance teams remove AWG. • Not a recognized cable in IEC 60228. • AWG relegated from (normative) part of standards to informative annex.

  8. CANENA Annual General Meeting • Early 2000s, • USNC SC23F connecting devices makes proposal to NEMA wire & cable section. • USNC TC 20 TAG formed. • Voted against renewal of 60228. • Too late to change standard. • Worked with Canada & Mexico.

  9. CANENA Annual General Meeting TC-20 biennial meeting, Berlin, Nov 2004. • North America’s case made by: • Richard Barker • Ron LAI

  10. CANENA Annual General Meeting • Day 1: • Frustrating meeting! • “AWG is a backward step”. • “North America is not Globally Relevant”. • “Conductor size is not an Essential Difference - just change to Metric”. • After much heated discussion - Study Group Proposed.

  11. CANENA Annual General Meeting • Day 2 • Study Group approved. • SG chair - Reimer Stubbe, Germany. – the most vocal objector from day 1! • Chair from WG 19 Mark Coates – UK. • Cenelec representative (Steve Mason – UK). • N America (Ron Lai US, Richard Barker US). • European (Gerhard Novac IT). • Non European (Antony Falconer ZA).

  12. CANENA Annual General Meeting • Inaugural Study Group meeting – Paris, May 2005. • 2nd edition of 60228: (1978). • Restricted to 4 classes. • Reduced number of sizes. • Deleted AWG. • 3rd edition of 60228: (2004). • Size based on DC resistance. • Decision to be a consensus driven group (EDR on hold). • Only conductors for power and control cables. • Comments and minutes issued to North American countries.

  13. CANENA Annual General Meeting • Delay……... • Attempt to call a meeting at Nov 05 Milan WG meetings – Failed. • Comments on meeting minutes from USNC forwarded to IEC. • Meeting arranged for May 2006 Paris. • Reimer Stubbe retires. • Ron and Richard decide to host dinner/drinks.

  14. CANENA Annual General Meeting Second Study Group meeting – Paris, May 2006.

  15. CANENA Annual General Meeting • Second Study Group Meeting – Paris, May 2006. • Three part approach: • Publication of 60228 as a technical report. • Addition of AWG as “Part 2” of 60228. • Merging of both parts to one. • Study group consensus reached. • Survey of IEC Member Countries proposed. • Sept. 2006 - Study Group Activity Report issued to TC20 for London Biennial meeting approval. • Work commenced on Technical Report pending approval of SG report from TC20 committee

  16. CANENA Annual General Meeting • TC-20 Biennial meeting, London, Oct. 2006. • Friendly welcome and US officially thanked for participation at WG level (since Berlin). • SG Report presented by Cenelec Representative (Steve Mason UK). • Proposal (Belgium) to have unique TR number not IEC 60228 Part 2 to prevent roll-on effect to other standards. • All unanimously accepted. • Survey dropped as redundant.

  17. CANENA Annual General Meeting • TC-20 Biennial meeting, London, Oct. 2006. • Unconfirmed minutes issued Nov 2006. • Step 1 Technical report 1Q 2007 (WG19) with metrification of size via DC resistance. • Step 2 Technical report number to be retained for a “publication” with an “informative” reference in IEC 60228 (2010)(start 2007). • Step 3 Harmonization of “publication” and IEC 60228 (2015 or 2020). • This has caused some confusion that will be addressed in London March 2007 (WG19). • There is a need to read SG report alongside the minutes.

  18. CANENA Annual General Meeting • Reference Documents: • ECBL/C/277/03 - Europacable article to keep North America out of IEC markets. • IEC 20/729/INF - Discussion document dismissing AWG. • IEC 20/745/RM - Berlin minutes. • IEC 20/760/INF - Study group membership. • IEC 20/836/INF - Study group report. • IEC 20/863/RM - London minutes.
