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 121.
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.
