The following correction factors are provided for deviating ambient temperatures:
Cross-sections of round conductors
The standard values of the cross-section of round copper conductors as well as the ap-
proximate ratio of metric ISO and AWG/MCM values are shown in the following table.
Standardized cross-sections of round conductors:
ISO cross-section [mm²]
Note
The line corresponds to a value when the connection possibilities are taken into account.
