Which NEC reference addresses service disconnecting means?

Which NEC reference addresses service disconnecting means?

• A. NEC Article 408
• B. NEC Section 600.5(A)
• C. NEC Section 230.71(B)
• D. NEC Section 220.46

Answer: (C)

The main idea being tested is where the NEC tells you about the location and accessibility of the service disconnecting means. The service disconnecting means is the device that allows shutting off power to the entire building, and the code specifies where it must be located so it’s readily accessible. The best choice points to the section that specifically addresses the required location of the service disconnecting means. That part of the code establishes where the disconnect must be placed so it can be quickly reached by occupants and emergency responders, typically at a readily accessible location near the point of entry or outside the building. The other references deal with topics other than the service disconnect location, so they don’t address where the service disconnecting means must be located.
