#Wire splice connector free#
The free end of the pigtail is then connected to a threaded screw opening on the metal box, using a green grounding screw. For metal electrical boxes, run a third grounding pigtail (bare copper or green insulated) to the two bare copper circuit grounding wires, using a wire connector. The bare copper circuit grounding wires should also be joined together in the box, using an approved connector. With these connectors, you simply push the bare end of the wire into a grip-fit socket on the connector.
Some electricians like to wrap a loop or two of electrician's tape around the base of the wire nut and wires to help reinforce the wire connection.Īnother type of approved wire connector is the push-fit connector. There should be no bare wire exposed at the bottom of the wire nut. However you do it, the wires should be connected securely enough that they don't come free from the wire nut when you tug on them. However, some wire nut manufacturers instruct to simply hold the two parallel wires together, then twist the wire nut over the bare ends of the wires in a clockwise direction. With standard wire nuts, some electricians prefer to twist the wires together first with pliers, then screw the wire nuts over the ends of the wires. Using approved wire connectors, join together the conducting wires with similar insulation colors. The Spruce Home Improvement Review Board.
