Stripping wires is the process of removing the outer insulation from an electrical wire to expose the conductive metal beneath. This is necessary for making electrical connections, such as when installing a new light fixture or repairing a damaged wire.
There are a variety of tools that can be used to strip wires, including wire strippers, utility knives, and even your teeth. However, it is important to use the correct tool for the job, as using the wrong tool can damage the wire or insulation.
