How the cable size for a motor is decided

Answer Posted / dilanka

motor drowse starting current which will be around 2-3 times
the rated current. so cable size going to be increase.How
ever it is suitable to select 125% or 130% current rate for
cable because the cable can withstand without any damage for
few second. you must check the cable manufacturing data to
find this specific time and it should be more than the
starting time period of the motor.
