Which NEC article covers the general electrical safety requirements for electrical installations?

• A. Article 210 (Wiring methods)
• B. Article 500 (Hazardous locations)
• C. Article 110 (General safety)
• D. Article 398 (Cable trays)

Answer: (C)

The key idea is that there is a single article that sets the broad, overarching safety requirements for electrical installations. This article provides the baseline rules for safe installation, including general safety practices, the proper handling of equipment, enclosures, service equipment, and general wiring guidance that apply across most types of installations. It acts as the foundation that all other, more specialized articles build upon.

The other topics referenced by the remaining articles are narrower in scope: one focuses on wiring methods for circuits, another covers safety considerations in hazardous locations, and another deals with cable trays as a supporting structure. None of these alone establish the overall safety framework for electrical installations, making the broad general-safety article the correct choice.
