5.4.1 Typical cross-sections
The following table provides an overview of typical cable cross-sections (copper cable with PVC insula-
tion, 30 °C ambient temperature, continuous mains current max. 100% rated input current). Actual
cable cross-section requirements may deviate from these values due to actual operating conditions.
