Line protection and core cross section
Comply with the regulations of the specific country and for the specific machine regarding fusing and selecting cable cross sections. If required, also adhere to the notes on UL compliant installation.
Always size the shared neutral conductor for the total current when using several 1-phase units. Also size it according to the total current even if the unit connections are distributed over the three mains phases. This is because the third supply current harmonics are always cumulative.
Select the cross section of the motor cable so the voltage drop is as small as possible. An excessively high voltage drop means that the full motor torque is not achieved.
