When selecting, connecting, and routing power cables, follow local safety regulations and
rules.
When the external conditions such as cable layout or ambient temperatures change,
perform verification in accordance with the IEC-60364-5-52 or the local regulations.
The currents listed in the table "Recommended cross-sectional areas for power cables" are
measured at a rated voltage of 380 V; if the rated voltage is 400 V, multiply the currents by
0.95; if the rated voltage is 415 V, multiply the currents by 0.92.
When the primary loads are non-linear loads, increase the cross-sectional areas of the
neutral wires 1.5–1.7 times.
The recommended cables are applicable only when the following requirements are met:
● The cables are routed over a ladder or bracket in a single layer (E or F in IEC
60364-5-523).
● The ambient temperature is 30°C.
● The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
● Single- or multi-core 90°C soft power cables with copper conductors are used.
● It is recommended that AC power cables be no longer than 30 m and DC power cables
be no longer than 40 m.
