Is a means of disconnection required for every motor?

Every motor requires a means of disconnection to ensure safety and compliance with electrical codes. This requirement is in place to allow for the safe maintenance and servicing of the motor. A means of disconnection can be an isolator switch, circuit breaker, or similar device that physically interrupts the power supply to the motor. This is crucial not just for safety during maintenance but also to ensure that the motor can be fully powered down in the event of an emergency or fault condition.

Ensuring a reliable means of disconnection contributes to worker safety by minimizing the risk of accidental electrocution or equipment damage when the motor is being serviced. The inclusion of this safety measure in standards and regulations reflects the importance of having every motor equipped with a way to safely disconnect it from its power source, regardless of the motor's size or application.
