The restraining cord on the pendant control box serves primarily to prevent what?

• A. Keep within reach
• B. Prevent strain on electric cord
• C. Control swinging loads
• D. Keep the control box off the floor

Answer: (B)

The main idea is protecting the electrical cord from damage by limiting how far the pendant control box can move away. The control box is powered through a flexible cord, and if it’s not restrained, movement of the crane or operator can pull, twist, or yank that cord. This can cause insulation wear, fraying, or a loose connection, creating electrical hazards or losing control. The restraining cord keeps the pendant near the operator and reduces tension on the cord, helping prevent damage and extending the cord’s life.
