What does Article 225 of the National Electrical Code cover?

Article 225 of the National Electrical Code specifically addresses the requirements for outside branch circuits and feeders. This article is vital for ensuring that electrical installations serving buildings or structures located outside of the main building or structure meet safety and operational standards. It includes regulations related to the installation of conductors, methods of wiring, and other essential elements that define how electricity can be safely delivered to outdoor areas.

Understanding this aspect is crucial as outdoor installations face unique challenges, such as exposure to environmental factors like moisture and temperature variations. Therefore, the guidelines laid out in Article 225 help to mitigate risks associated with these installations, ensuring that they are both functional and safe for use.

The other options, while related to various aspects of electrical work, do not align with the specific focus of Article 225, which is uniquely centered around outside circuits and feeders. This distinction is important for professionals who are working on outdoor electrical systems and need to adhere to the proper regulations as laid out in the NEC.
