Answer / muhammed

first you calculat the load after that you calculate the current using this equation I= P/(ROOT3*V*POWER FACTOR)
after there is one cable selection table(available in google) using current rating check that cable and select the cable size

If two hack saw blades, seperated by 1mm thick paper,are connected across 230volts, and immersed in water,then they start getting heat. This is fact,i dont know how they get heated.Blades are not directly connected together. Please if anybody knows the fact ,revert back to me
