• A. Article 210 (Wiring methods)
• B. Article 500 (Hazardous locations)
• C. Article 392 (Cable trays)
• D. Article 110 (General safety)

Answer: (D)

Inspection and testing after installation are governed by the general safety requirements for electrical installations. This article sets the overarching rules for safe workmanship and the checks needed to verify a job is complete and safe before energization, including the processes of inspecting and testing equipment and installations. It provides the broad standards that apply regardless of wiring method, location classifications, or specific supports. The other articles focus on particular topics—wiring methods, hazardous locations, or cable trays—rather than the overall safety and verification practices applied after installation.
