Yellow twist on wire connectors for 22 awg to 10 awg wires. Yellow twist on wire connectors are suitable for connecting multiple larger wires (up to 10 gauge) together. To use the connector, strip off about 3/4 inch of insulation from your wires and twist the exposed ends together in a clockwise direction. Place the yellow twist on connector over the wires and tighten it down. The square edges of the metal spring inside the housing will bite into the copper strands of your wires and thread itself onto the bundle. The tighter you twist the connector, the tighter the connection will be. To remove the connection, simply untwist the yellow connector. Rated for use up to 300 volts.
