Question:
Hi Charlie Trout, absolutely love the dialog that comes from discussing the Code Question of the Day with my co-workers every morning. As an Inspector I was asked about the junction boxes that come with the LED ceiling recessed luminaires, and the required support. Do the junction boxes that seem to float above the drywall ceilings need to be secured to a rafter, joist, or other support member above the drywall? We have had a grand go about on this one, I see some inspectors asking that they be secured, others never see them in finish stage after the rough of wires in place awaiting drywall. I look forward to what Charlie says about this one. Regards, Bill Schell

Answer:
Hello Bill, thank you for participating and happy to hear that you and your co-workers are enjoying the CQD. This is a great question, highlighting the common occurrence of ignoring the provided installation instructions. The “Canless” recess LED luminaires you mentioned in the question have integral termination compartments which are not covered by the scope of Article 314, therefore the support requirements in Section 314.23 would not apply. However, luminaires of this type that are listed by a recognized NRTL, will likely require the termination compartment to be supported in the installation instructions. It is important to emphasize that the installation instructions are indeed part of the listing of that luminaire. Failure to follow the installation instructions violates the listing of that luminaire.
