Orange twist on wire connectors can accommodate wire sizes from 22 gauge to 14 gauge. The orange thermoplastic shell has ridges for easy twisting of the connector. An inner wire spring bites into the copper strands of your wires allowing the connector to 'thread' itself down onto the wires. Multiple wires can be connected together by simply twisting their exposed ends together in a clockwise direction. An orange twist on wire connector is a good multi-purpose connector suitable for automotive electrical use, as well as commercial and industrial electrical applications. The connectors can easily be removed by simply untwisting them.
