Why do conductor clamps need to be equipped with serrations on their jaws?

The correct choice is focused on the function of the serrations in a conductor clamp. Serrations on the jaws of conductor clamps are designed to create a stronger grip by digging into the surface of the conductor. This enhances the mechanical connection and helps to ensure that the clamp does not slip or loosen over time, especially in environments where vibration or movement may occur.

While biting through corrosion may seem appealing, the primary purpose of the serrations is to enhance grip rather than to penetrate or remove corrosion itself. The other options related to easier installation or reducing electrical resistance do not directly address the specific function of serrated jaws in maintaining a secure and stable connection, which is critical for safe and effective electrical installations.
