The formular of how to calculate a cross sectional cable to feed an electric motor.
Examle: 15KW, 26.1A, 415V. Calculate the cable size in mm2

Answer Posted / wareagle

You don't have to calculate it. Just look it up in this
table. http://www.energy-
solutions.co.uk/cable_conductor.html
Looks like 4 mm^2 would do the job.
