IEC 62893-3:2017 pdf download.Charging cables for electric vehicles of rated voltages up to and including 0,6/1 kV
1 Scope
This part of IEC 62893 applies to cables for AC charging according to modes 1 , 2 and 3 of IEC 61 851 -1 . The cables are of rated voltages U 0 /U up to and including 450/750 V. Ordinary duty cables with rated voltage 300/500 V are only permitted for charging mode 1 of IEC 61 851 -1 . Maximum conductor operating temperature for the cables in this document is 90 ºC. The test methods specified are given in IEC 62893-2, IEC 60245-2, IEC 60332-1 -2, IEC 62821 -1 :201 5, Annex B and in the relevant parts of IEC 6081 1 . IEC 62440 is intended to be used as guidance on the safe use of cables in this document together with specific guidance in Clause 5 of this document.
