It is not a good practice to supply lamps and large motors from the same circuit. Which of the following is NOT the correct reason?
When the motors are started, the large starting current causes a voltage drop on the feeder, which will make the lights grow dim or blink.
Overloads and short circuits are more common on motor circuits and should not be the cause of putting the lights out.
When the motors are started, the small starting current causes a voltage drop on the feeder, which will make the lights grow dim or blink.
Frequently it is more economical to operate motors on a higher voltage than that of the lighting circuit.
