What tool is used to cap off wires that are not being used?

The use of wire nuts is a common practice in electrical work to cap off unused wires safely. Wire nuts, also known as wire connectors, are designed to secure and insulate connections between several wires. When wires are not being used, capping them with wire nuts helps prevent accidental contact, which can lead to short circuits or electrical shocks.

Wire nuts are typically color-coded to indicate the size of the wires they can connect, ensuring that the right size is used for the job. This provides a reliable and secure method of insulation that protects unconnected wires from exposure, moisture, or potential damage.

Using wire strippers is meant for removing insulation from wires, while electrical tape can provide insulation and securing capabilities but isn't designed solely for capping off wires. Connectors can serve various purposes, including joining wires, but wire nuts specifically fulfill the function of capping unused wires, making them the preferred choice in this scenario.
