Which NEC article covers service conductors and the equipment for control and protection of services?

• A. Article 230
• B. Article 810
• C. Article 300
• D. Article 400

Answer: (A)

Service conductors and the equipment that controls and protects the service are addressed by NEC Article 230. This section covers the wires that bring utility power to the building, including the meter and the main service disconnect, as well as the overcurrent protection configured for the service. It also outlines how the service equipment should be installed, where it can be located, and the grounding/bonding requirements related to the service. The other NEC articles focus on different areas—signaling and communications circuits, general wiring methods, and flexible cords and cables—so they don’t cover service conductors and the equipment used to control and protect the service.
