What is the function of the cable grip in a plug?

• A. It prevents wires inside from being pulled out if the cable is tugged
• B. It prevents short circuits
• C. It makes the plug heavier
• D. It changes the color of wires

Answer: (A)

The cable grip acts as strain relief for the plug. When the cable is pulled, the grip clamps around the outer sheath and anchors it to the plug body, so the force doesn’t pull on the delicate wires or their connections inside. This keeps the internal connections secure and prevents damage or loosening that could lead to exposed conductors or faults. It isn’t about preventing short circuits directly, changing weight, or altering wire color—the grip’s job is simply to protect the integrity of the internal wiring by resisting pulling on the wires.
