The cross-section of the power cables must be suitable for the prevailing ambient conditions. 

The following factors determine the cross-section: 
●  The current set on the device 
●  The cable installation type 
●  The ambient temperature 
●  The type of material (PVC, rubber) 
The following maximum current-carrying capacities apply for PVC power cables when 

installed, for example, in the cable duct (depending on the ambient temperature):
