What is a dropout plate?

• A. Flat metal plate used to cover openings
• B. Metal plate with a curved surface to protect the cable as it enters or exits the tray
• C. Plastic clip securing the cable
• D. Permanent insulating sleeve

Answer: (B)

A dropout plate is a metal plate fitted to a cable tray at the point where cables exit or enter, with a curved surface that guides and protects the conductors as they transition from the tray. The curved ramp provides a smooth path, reducing abrasion and bending stress on the insulation as cables are pulled through or out of the tray. This makes it the best description because it directly addresses protection during entry/exit and the need for a gentle transition. The other options describe a flat cover plate, a cable clip, or an insulating sleeve, none of which match the function of guiding and protecting cables at the tray exit/entry.
