17 Cable selection 3”WPS®-CP Submersible drop cable to the motor (three phase) The table below shows the maximum length of the submersible drop cable between the controller and the motor for the different cable sizes and motor powers. The cross-sections of the cable are calculated according to a 3% voltage drop (IEC 60364:2001). The pump will cut out if the supply voltage falls below 185 V. In case the total length of the electrical power cable between controller and motor exceeds 100m, an extra filter to protect the motor from burning is required. See accessories. Supply cable to the controller (single phase) In case you want a longer electrical cable, you must check the cable section following the table below.
