Note that these values are only recommendations, each in-
stallation is different and the cable cross section should be
calculated individually each time.
Warning: failure to select the correct cable cross - section may
cause equipment damage or electrical fire.
When using TNS and TNC - S systems, it is recommended to
use 5 single core cooper wire. When using TT system with
separate grounding, make sure that the grounding cable cross
-
section match the power supply cable cross - section.
The absolute maximum cable cross - section must be no
greater than 35mm2. The thicker cable will not fit the cable
terminals inside the charging station.
