Note: Resistance values are calculated from a resistivity of 0.01777 µΩ.m at 20°C. This is equivalent to a conductivity of 97% IACS. Maximum values
of
resistance are calculated from minimum diameters.
Note: Minimum breaking loads for nominal diameters up to and including 4mm are based on the minimum diameter of conductor and a tensile strength
of 415 N/mm² and for nominal diameters greater than 4mm they are based on the minimum diameter of conductor and a tensile strength of 400 N/mm².
