What is an essential tool in forming connections within motor wiring?

Wire strippers are essential tools in forming connections within motor wiring because they are specifically designed to remove the insulation from electrical wires without damaging the metal conductor beneath. Properly stripping the wire is crucial for creating secure and effective electrical connections, which ensures that the motor operates efficiently and safely. Accurately prepared wires allow for better contact when connected to terminals, reducing the risk of electrical shorts and failures.

In contrast, while a power drill can be useful for other applications and a screwdriver may assist in fastening components, they do not fulfill the primary need of preparing wire connections. A heat gun is typically used for tasks such as heat shrink tubing but does not directly assist in the actual formation of connections within motor wiring. Therefore, wire strippers are uniquely suited to the task at hand, making them the correct choice.
