In case of any three pointstarter NVC is connected to the shunt field winding so if voltage is fall certain value the no volt release coil de magnetise so motor will be off. But in case of four point starter the no volt release coil is directly connected to the supply so the NVC no way the demagnetized.

is that any software calculator to calculate the size of cable
