Where is flexible cord permitted to be connected to fluorescent luminaires?

1. only at the ends

2. if it is insulated

3. when it is visible its entire length

4. if it has a strain relief

The correct answer is: when it is visible its entire length

Flexible cord is permitted to be connected to fluorescent luminaires when it is visible its entire length because this ensures that the cord can be monitored for signs of wear, damage, or other issues that could pose a risk of electrical hazard. Visibility helps inform both users and installers about the condition of the cord, allowing for preventive maintenance or replacement before a failure might occur. In many wiring methods and codes, if a flexible cord is not installed in a manner that keeps it visible, it may be at risk of being pinched, damaged, or affect the luminaire’s operation due to not being adequately supported. Therefore, allowing visibility for the entire length of the cord is a key safety consideration in ensuring that it remains intact and operates safely. While other factors such as insulation, strain relief, and connections at the ends may relate to the overall safety of the installation, they do not specifically address the importance of visibility along the entire length of the flexible cord, which is critical for ongoing monitoring and safety compliance.
