Note
The recommended cable section for power cables are only for the situations described below:
• Ambient temperature: < 30℃.
• AC loss is less than 3%, DC loss is less than 1%, the length of the AC power cables should be
no longer than 50 meters and the length of the DC power cables should be no longer than
30 meters.
• Currents listed in the table are based on the 380V system (line to line voltage). For 400V
system, the current is 0,95 times and for the 415V system the current is 0,92 times.
• The size of neutral lines should be 1,5-1,7 times the value listed above when the
predominant load is non-linear.
