A dropout plate serves what function in cable tray systems?

• A. Grounding the system
• B. Protecting cable as it enters or exits the tray
• C. Securing cables with clamps
• D. Providing strain relief

Answer: (B)

In cable tray systems, a dropout plate is placed at the edge where cables leave or enter the tray to provide a smooth, protective transition. It shields the insulation from the sharp metal edge of the tray, preventing abrasion and snagging as conductors are pulled through or moved to another run. This targeted protection at entry/exit points is what the dropout plate is designed to do, which is why it best fits the description of protecting cable as it enters or exits the tray. Grounding, securing with clamps, and strain relief are handled by other components or fittings, not by the dropout plate.
