European Norm



IEC 60228 ED4:2023 (EN) specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2, for conductors in electric power cables and cords of a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for fixed installations and flexible copper conductors.
This document does not apply to conductors for telecommunication purposes.
The applicability of this document to a particular type of cable is as specified in the standard for the type of cable.
Unless specified otherwise in a particular clause, IEC 60028 ED4 relates to the conductors in the finished cable and not to the conductor as made or supplied for inclusion into a cable.
Conductors described in this document are specified in metric sizes.
Informative annexes provide supplementary information covering temperature correction factors for resistance measurement (Annex B) and guidance on dimensional limits of circular conductors (Annex C).
This document has the status of a horizontal publication in accordance with IEC Guide 108.
