How the cable size for a motor is decided




Answer Posted / arvind

The cable size of motor depend on rated current of motor,
but as the motor draw more current at starting which will
be around 2-3times the rated current, so cable size will
going to be increased i.e, wherever we will calculate we
take 20% extra for selection of your cable
