What tool would be used to splice wires together?

The tool used to splice wires together is splice connectors or wire nuts. These components are specifically designed for connecting multiple wires securely and electrically. When wires are spliced, it is essential to ensure that the connection is not only secure but also insulated to prevent short circuits or electrical hazards. Wire nuts twist onto the joined ends of wires, creating a tight seal that keeps the conductive parts together while also providing insulative protection against exposure. This makes them the most suitable and safe choice for splicing wires compared to other tools.

While screwdrivers and pliers are useful for various tasks, they do not serve the specialized function of connecting and insulating wire ends. Wire cutters are intended for cutting wires rather than joining them. Thus, splice connectors or wire nuts are the ideal tools for effective and safe wire splicing.
