For general requirements applicable to luminaires, which article should be referenced?

To determine the appropriate article for general requirements applicable to luminaires, Article 110 of the National Electrical Code (NEC) should be referenced. Article 110 provides the fundamental requirements for all electrical installations, including general design, installation practices, and details related to equipment compliance. It sets the groundwork for ensuring safe and reliable electrical systems, which applies to luminaires among other electrical devices.

While Article 410 specifically addresses luminaires, including their installation and configuration, it builds on the foundational requirements set forth in Article 110. This means that to fully understand the contextual requirements for luminaires, one must also consider the broader standards established in Article 110.

Articles 300 and 500 cover other aspects—Article 300 deals with general wiring methods and installation requirements, while Article 500 relates primarily to hazardous (classified) locations, which do not pertain directly to general requirements for luminaires. Therefore, when discussing general requirements that affect luminaires, Article 110 is the most relevant and appropriate reference.
