Dear sir, my knowledge about cable size determination is limited. Though I read examples I could not calculate the Cable size required for electric driven pump 40 KW, 380 Volt, 50 HZ, 50 meter from transformer and it is three phase star delta starting. Please help as there is no one in my surroundings to help.
