What tool should be used to twist two wires together when installing wire nuts?

• A. Needle-nose pliers
• B. Linesman pliers
• C. Cable rippers
• D. Utility knife

Answer: (B)

Using linesman pliers to twist two wires together is the best choice for this task. Linesman pliers are designed with a strong gripping surface and cutting edges, which make them ideal for handling wire connections. The wide jaws allow for a strong grip, enabling the user to firmly twist the wires together, ensuring a solid connection before installing wire nuts. This is important for creating a reliable and safe electrical joint.

In contrast, while needle-nose pliers can also twist wires, they do not provide the same level of strength and leverage as linesman pliers for this particular application. Cable rippers are intended for cutting or stripping insulation from wires rather than twisting them together, and a utility knife is primarily used for cutting materials and is not suitable for manipulating wire connections. Therefore, using linesman pliers is the most effective and safe choice for twisting two wires together.
