Step 1
Cut off the length of wire you need from a roll and remove about 4 inches of sheathing from either end with a utility knife. Cut around the perimeter of the sheathing, being careful not to cut into the wires underneath, and pull it off with pliers.
Step 2
Separate the wires underneath. Remove about 1/2 inch of plastic coating from the white and black wires with the splicing tool. Take the paper off of the bare wire.
Step 3
Unscrew the screws holding the male connector together and separate it. Pass one end of the ROMEX® through the hole in the bottom piece and move it along the wire.
Step 4
Connect the wires to the nuts inside the top part of the connector. Connect the black wire (hot) to the brass nut, the white wire (neutral) to the silver nut and the bare wire (ground) to the green nut. You may have to make a little bend in the ends of the wires to hook them around the nuts. Do this with pliers and bend the wire clockwise.
Step 5
Slide the bottom up into place against the top of the connector. Verify that the sheathing extends into the hole of the connector. If it doesn't, disconnect the wires and trim them back a little.
Step 6
Fasten the top and bottom of the connector with the screws provided and tighten them well. It is a good idea to wrap some electrical tape around the hole where the wire comes out. Repeat steps 2 through 6 with the female connector.
