What does Article 225 cover in the National Electrical Code?

Article 225 of the National Electrical Code specifically addresses Outside Branch Circuits and Feeders. This article outlines the requirements for electrical systems that supply power to outdoor locations and surrounding areas, ensuring safety and proper installation practices for circuits that extend beyond buildings.

The rationale behind this coverage is essential for managing the challenges posed by outdoor installations, which can be subjected to different environmental conditions compared to indoor circuits. This article includes guidelines for the installation of conductors, equipment, and the necessary protection methods when running circuits outdoors, addressing concerns such as weather resistance, accessibility, and adequate separation from other structures to mitigate hazards.

The other choices, while relevant to electrical installations and safety, fall under different sections of the NEC. Services pertain to Article 230, which covers the supply of power to buildings, while grounding and bonding are covered in Article 250. Overcurrent protection is detailed under Article 240. Each of these articles serves distinct purposes within the NEC framework, highlighting the comprehensive approach the code takes to ensure electrical safety across various contexts.
