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 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 Stage 3: Produce new standard with a single rationalized range of conductor sizes (by 2020) Long term project
