3.9.1. Power Cable Cross-sections and Electromechanical Components of the
Power Circuit
Specifications for the drive wires, safety devices and operating devices are given in the tables below.
For the greatest drive sizes, wiring with multiple conductors for the same phase is recommended. For
example, “2x150” in the wire cross-section column means that two parallel-connected 150mm
2
conductors
per phase are used.
Multiple conductors must have the same length and must follow parallel paths so that current is evenly
delivered at any frequency level. Unparallel paths, even if their length is the same, result in uneven current
distribution at high frequency. The cross-sections given in the tables below apply to copper wires.
