To carry the line voltage

To reduce voltage drop

To carry load current

To reduce the power loss

To protect the motor from damage

To run the motor continuously at single phasing

To regulate the supply voltage

To protect the motor from over load

I.R = (Leakage Current/supply Voltage)

I.R = (Load Current/supply Voltage)

I.R = (supply Voltage/Leakage Current)

I.R = (supply Voltage/Load Current)
