Wire connectors are small devices used to join two or more electrical wires together. They ensure a secure and reliable connection, allowing electricity to flow smoothly between the wires. Common types of wire connectors include twist-on wire connectors, crimp connectors, and screw terminal connectors, each designed for specific applications and wire types. These connectors are essential in various electrical projects, from household wiring to automotive applications. Proper use of wire connectors helps prevent electrical shorts, reduces the risk of fire, and ensures the safety and efficiency of electrical systems.
