TRANSCRIPT
IEC Report to E10D-Fall 2008
Presentation by Ken Bow
IEC Technical Report TR6XXX
• Conductors of Insulated cables - Data for AWG and kcmil Sizes
• Step 1 of a 3 step process• Recommended by Study Group 60228• Means of introducing “AWG” sizes into the IEC
system• Provides resistance and dimensional detail
including metric cross-sections
Driving Forces
• IEC TC 20 recognizes need to produce a single harmonized standard
• Not intended for data cable, communications cable or winding wire
• AWG Sizes: 24, 22, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2, 1
• 1/0, 2/0, 3/0, 4/0• Kcmil sizes:250, 350, 500, 750, 1000, 1250,
1750, 2000
Procedure
• Stage 1: Produce TR with a range of AWG/kcmil conductors (24 AWG to 2000 kcmil)
• Stage 2: Develop TR into IEC Standard/Align with IEC 60228
• Stage 3: Produce new standard with a single rationalized range of conductor sizes (by 2020)
• Long term project
