For lighting equipment installed outdoors, which NEC Article must be complied with?

The correct answer focuses on Article 225 of the National Electrical Code (NEC), which specifically addresses the requirements for outdoor installations, including the installation of lighting equipment. Article 225 outlines critical details such as the installation practices, materials, and protective measures necessary to ensure that electrical systems are safely and effectively installed in outdoor environments.

When dealing with outdoor lighting, this article provides guidance on aspects such as the proper rating of equipment for wet and damp locations, as well as the appropriate wiring methods that should be used to protect against environmental conditions. This includes considerations for the durability of components and ensuring that any outdoor installation withstands possible exposure to moisture and other elements.

In contrast, while Article 210 covers branch circuits, Article 300 deals with general methods for wiring installation, and Article 310 focuses on conductors for general wiring, they do not specifically address the unique considerations that come into play with outdoor lighting systems. Therefore, adherence to Article 225 ensures compliance with safety standards tailored for outdoor electrical installations.
