How the cable size for a motor is decided

Answer Posted / sanjeev pal

motor cable is decided according to motor rated current
given in specification plate. WHEN MOTOR is initially
running condition then motor draw current 1.5 times more its
rated current. so this factor decided cable size of motor

example 10 HP MOTOR rated current is 14.7 or 15 ampere
when initial running condition draw 1.5 times more
14.7 * 1.5 = 22.05 ampere then current caring capacity
of cable is 22 Ampere must be necessary.
