Installations covered by the NEC include which of the following?

• A. Industrial substations
• B. Installations on public and private premises
• C. Recreational vehicles, floating buildings, and mobile homes
• D. All of the above

Answer: (D)

The NEC covers electrical installations in a wide range of settings to protect people and property, not just in typical buildings. Industrial substations are part of the electrical infrastructure where the NEC provides rules for wiring, grounding, overcurrent protection, and equipment safety. Installations on public and private premises include the wiring and electrical equipment found in buildings and on properties you own or occupy, as well as the outdoor portions of those installations. The NEC also addresses specialized situations like electrical systems in recreational vehicles, floating buildings, and mobile homes, recognizing their unique configurations and safety needs. Because the code applies to all of these contexts, the option that includes every one of them is the best answer.
