Which device could be used as a disconnecting means for a 2 horsepower, 240-volt, single-phase motor?

A disconnecting means is essential for ensuring safe operation and maintenance of electrical equipment, such as a motor. In the case of a 2 horsepower, 240-volt, single-phase motor, a suitable disconnect device must be able to handle the motor's load and provide a means to isolate the motor from the power source.

The correct answer indicates that either device mentioned in the choices can be used as a disconnecting means. This implies that both devices have the necessary voltage and current ratings to manage the load of the motor safely.

In practice, a disconnecting means must meet specific criteria, including being easily accessible and capable of providing a visible break in the circuit. It could be a circuit breaker, a fused disconnect switch, or a manual motor controller, all of which can handle the voltage and current for a 2 horsepower motor.

The flexibility in using either device reinforces the importance of adhering to electrical codes and standards that govern the operation of electrical equipment, ensuring that any chosen device not only meets the rating requirements but also complies with safety regulations. This adaptability is crucial for electricians to effectively maintain and troubleshoot equipment while ensuring safety protocols are in place.
