If multiple luminaires are on a branch circuit that is not multi-wire, is a disconnecting means required for every luminaire?

In the context of wiring multiple luminaires on a branch circuit that is not classified as multi-wire, a disconnecting means is not required for each individual luminaire if there is a light switch that effectively controls their illumination. This is in line with the National Electrical Code (NEC) provisions that allow for the application of a single disconnecting means for multiple luminaires as long as they can be turned off from a location that is readily accessible.

The reasoning here is focused on practical utility and safety. Having a single switch to control multiple luminaires simplifies operation and reduces the complexity of the wiring system. As long as the switch is properly rated and installed, and serves as a reliable means to disconnect power to the luminaires, additional disconnecting means for each individual luminaire is unnecessary.

This approach also supports greater efficiency in design and installation, allowing for cleaner setups without the need for excessive hardware, making it easier for users to manage lighting in a space effectively. It's important to always refer back to the NEC requirements to ensure compliance, and this specific scenario highlights the need for effective control rather than redundant disconnecting means.
