Expert Analysis

410.118 Luminaire Access to Other Boxes

Can a luminaire be installed in such a manner as to be the only access point to junction boxes located above or behind said luminaire? Answer: 2017 NEC…maybe? 2020 NEC… NO! The new provisions of 410.118 will exclude luminaires recessed in ceilings, floors, or walls from being used to access outlet, pull, or junction boxes or conduit bodies (unless the box or conduit body is an integral part of the listed luminaire). The intent of this new Code language is to clarify that a luminaire cannot be used to access junction boxes that are not associated with wiring for that luminaire as an integral part of said luminaire.
