What is required if electric-discharge or LED luminaires designed not to be supported solely by an outlet box are installed?

In the context of the National Electrical Code (NEC), when electric-discharge or LED luminaires are installed in such a way that they are not supported solely by an outlet box, it is essential to ensure that there is proper access to wiring. This requirement is in place to facilitate maintenance, inspections, or any future modifications that may be necessary. Providing access to wiring through suitable openings allows for safe and effective work on the electrical components of the luminaire without needing to disassemble the entire fixture or support structure.

This access serves a critical safety function, ensuring that electricians and maintenance personnel can easily reach the wiring connections to perform their duties, thereby maintaining safety standards and compliance with electrical codes. Access openings make it easier to check for wear, secure connections, and replace faulty components when necessary.

While additional structural support is important for many luminaires, especially heavy fixtures, the primary requirement highlighted is the provision of access through suitable openings. This ensures that all installations remain practical and safe for ongoing use and maintenance while complying with NEC regulations.
