Cabling - Danfoss VLT MCD 500 Pocket Manual

Cabling: How is cable selected for
a soft starter installation?
Cable selection criteria depends on the circuit and the location of
the soft starter within the circuit.
1. Supply cable rating > nominal fuse/MCCB rating > motor FLC x 1.2
2. Inside delta motor circuit cable rating > motor FLC x 0.7
Installation factors (including grouping, ambient
temperature, method of installation and single or
parallel cabling) may affect the cable's current rating.
Always follow the manufacturer's guidelines and derate
appropriately.
