The service conductors and service equipment are governed by which NEC article?

• A. Article 215
• B. Article 334
• C. Article 230
• D. Article 300

Answer: (C)

The service conductors and service equipment are governed by the article that covers the supply side of the electrical system, including the conductors from the utility to the building and the main service equipment. This article sets the rules for service disconnects, overcurrent protection at the service, and how the service is connected and sized. In contrast, other articles address different parts of wiring: one focuses on branch circuits and feeders, another on nonmetallic-sheathed cable rules, and another on general wiring methods. So the article that specifically directs service conductors and service equipment is the one that addresses the service, its disconnects, and related protections.
