Typical power cable sizes
The table below gives copper and aluminium cable types with concentric copper
shield for the drives with nominal current. See also Terminal and lead-through data
for the power cables on page 129.
1) The cable sizing is based on max. 9 cables laid on a cable ladder side by side, three ladder type
trays one on top of the other, ambient temperature 30 °C (86 °F), PVC insulation, surface
temperature 70 °C (158 °F) (EN 60204-1 and IEC 60364-5-52). For other conditions, dimension the
cables according to local safety regulations, appropriate input voltage and the load current of the
drive.
2) The cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at
40 °C (104 °F) ambient temperature. Not more than three current-carrying conductors in raceway or
cable or earth (directly buried). For other conditions, dimension the cables according to local safety
regulations, appropriate input voltage and the load current of the drive.
