What is the requirement for the fluorescent luminaire disconnecting means that utilizes double-ended lamps?

The requirement for a fluorescent luminaire disconnecting means that utilizes double-ended lamps is that it must be located in sight of the disconnecting means. This provision ensures that anyone servicing or working on the luminaire can easily see and access the disconnect, which promotes safety by allowing the electrical energy to be cut off before any maintenance takes place.

Having the disconnecting means in sight allows for instant recognition and reduces the chances of accidental re-energization while work is being performed. It is part of safe work practices outlined in the National Electrical Code, underscoring the importance of clear visibility and accessibility in electrical installations.

While other options may seem reasonable, they do not fully address the critical safety concern of visibility and immediacy. For example, a disconnecting means that is located remotely from the luminaire could increase the risk of accidents, as the technician may not be fully aware of the current state of the luminaire when performing maintenance. Therefore, the key safety aspect highlighted in the requirement focuses on ensuring that those working on the luminaire can easily and safely disconnect power.
