When applying capacitors on the secondary of a motor circuit disconnecting means the capacitor cables must be sized to 1/3 the motor conductors.
1. I believe this is because when the motor is disconnected, the motor ends up supplying vars to the cap... there will be an increase in voltage and more current through the capacitor wires. How did the code come up with 1/3 the size?
2. Is it 1/3 the motor conductors or motor load? Why?
Thanks in advance
