How often should trough assemblies, hand hole, and pull box be inspected?

• A. Daily
• B. Weekly
• C. Monthly
• D. Quarterly

Answer: (A)

Daily visual checks of trough assemblies, hand holes, and pull boxes are essential because these access points expose wiring to the operating environment and potential damage. A quick daily inspection helps catch moisture intrusion, corrosion, damaged or missing covers, loose fasteners, dirt or debris buildup, and any signs of overheating or arcing. Addressing these issues right away reduces the risk of electrical shock, short circuits, or fires and keeps the system safe for the next shift. More thorough maintenance tasks, like tightening connections or insulation testing, are performed on longer intervals, but the daily checks act as the first line of safety and reliability.
