Types of Wire Connectors & Their Uses Wire connectors are electrical components used to join, terminate, branch, extend, or connect electrical conductors safely and reliably. The correct connector is important because poor connections can cause high resistance, overheating, voltage drop, arcing, insulation damage, equipment failure, or fire. Connector selection should consider the conductor material, wire size, current and voltage rating, solid or stranded conductor, number of conductors, environmental conditions, temperature, vibration, enclosure type, and applicable electrical standards. 1. Twist-On Wire Connector Often called a wire nut, this connector is twisted over two or more stripped conductors. An internal metal spring grips the wires while the outer insulated body provides protection. Common uses: Lighting circuits Junction boxes Residential wiring Small branch circuits Joining compatible copper conductors Key point: Use only with the conductor sizes, quantities, a...
