Typical Power Cable Sizes - ABB ACS880-204 Hardware Manual

Typical power cable sizes

The tables below give current carrying capacity (I
insulated cables. A correction factor K = 0.70 is used. Time const is the temperature time
constant of the cable.
The cable sizing is based on max. 9 cables laid on the cable trays side by side, three ladder
type trays one on top of the other, ambient temperature 30 °C (EN 60204-1 and
IEC 60364-5-52).
