Is a manually operable switch or circuit breaker equipped with a handle permitted as a disconnecting means?

• A. Yes
• B. No
• C. Only if located outdoors
• D. Only for lighting circuits

Answer: (A)

A disconnecting means is a device that can safely interrupt all conductors of a circuit and provide a visible break. A manually operable switch or circuit breaker with a handle is designed to be opened by hand and clearly shows the circuit is opened, so it meets that requirement. The handle ensures real, manual control, which is essential for a disconnecting means. There’s no rule that it must be outdoors or only for lighting circuits; those are just restrictions that don’t apply here. As long as the device is accessible and properly rated for the circuit, it can serve as the disconnecting means.
