The size of cable needed for an electric motor depends on several factors, including the motor's power, voltage, and the distance between the motor and the power source.
When selecting the correct size cable for motor supply you can use the simple calculator below.
The calculator assumes the cable type is multicore PVC, single phase voltage is 230V, three phase voltage is 415V, and the cable length is less than 50meters.

The recommended calculated cable sizes are intended as a guide only. In all cases, in providing this cable size calculation certain assumptions will have been made. It remains the responsibility of the user to ensure all data and assumptions are correct and that any cable used is suitable for its intended purpose.
