Can a manually operable switch be used as a disconnecting means?

A manually operable switch can indeed be used as a disconnecting means when it meets specific criteria outlined in the National Electrical Code (NEC).

For a manually operable switch to serve as a disconnect, it must be rated for the intended load and installed in a manner that ensures it can safely interrupt the flow of electrical current. Additionally, the switch must provide a clear and visible means of isolation from the power source, which is crucial for safety during maintenance or emergency situations. The switch should also be easily accessible to personnel, allowing them to operate it without the use of specialized tools.

This capability of a manually operable switch is particularly important in ensuring compliance with safety standards and creating a safe working environment when servicing electrical systems. Thus, a properly rated and installed manually operable switch satisfies the requirements necessary to be considered a disconnecting means under the NEC.
