38 Planning the electrical installation

Not allowed AC output power cable types

Typical DC input power cable sizes
The typical minimum DC input cable sizes based on the number of inputs and the nominal
input current. The calculations are based on the current-carrying capacities and correction
factors of IEC 60364. 90
°
C cables, ground cabling (installation method D2) and maximum
temperature of 40
°
C in the ground are assumed. The cables must have sufficient cooling
distances, with a maximum of four cables touching each other.
If minimum cable size is not mentioned, there is no standard cable available. Contact your
cable manufacturer for special cable availability. Calculate the cable dimensioning based
on local regulations and installation conditions.

Typical AC output power cable sizes
Typical AC cable sizes based on the nominal output current. The calculations are based
on the current-carrying capacities and correction factors of IEC 60364. 90C cables, tray
cabling (installation method F) and a maximum temperature of 50
°
C in the air are
assumed. The cables must have sufficient cooling distances, with three loaded conductors
on trefoil distance between bundles 0.25m.
Symmetrical shielded cable with individual shields for each phase conductor is
not allowed on any cable size for output cabling.
