Indicative values based on the following elements:
* IEC 61439-1 and 60364-5-52
* calculation for copper conductors / cables grouped and enclosed with a permissible temperature of 70 ° C and an ambient
temperature around 55 ° C cables
* the length of the cables is not taken into account
(2)
For power supply cross-sections, enclosures equipped with supply end protection are equivalent to a single enclosure, even if the
enclosure is double or triple.
