 Typical power cable sizes
The table below gives copper and aluminium cable types for different load currents. 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, PVC insulation, surface
temperature 70 °C (EN 60204-1 and IEC 60364-5-52/2001). For other conditions,
dimension the cables according to local safety regulations, appropriate input voltage and
the load current of the drive.
 Typical power cable sizes (US)
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.
