Current carrying capacity iec

This document and its precursors were created due to a need for a standard definition of cable conductor size. The main problem being that not all copper has the same resistivity value, so, for example, a 4 mm conductor from two different suppliers may have different resistance values. Instead this document describes conductors by their nominal size, determined by resistance rather than physical dimensions. This is a key distinction as it makes a standardized definition o… WebETAP IEC 60092 provide a complete current capacity sizing calculations for power cables concerning electrical installations in seagoing ships and fixed or mobile offshore units for …
