The purpose of connecting a capacitor in star- delta motor
is to improve the capacitance (specially at the start). So
we can connect the capacitor in star connection, in parallel
to the motor.

we have 3 phase 4 wire supply 230/415 V.AC and our distribution is single phase or we have all single phase 220 v,ac operated appliances. and noted the current with help of clamp meter Red to N = 20 Amps. Yellow to N = 45Amps and Blue to N = 30 Amps ( total is 95 Amps ) what will be neutral current on the main .
