Wire Nut is the trade name for a twist-on wire connector manufactured by Hont Electrical Co.,Ltd. It is often used interchangeably with generic brands of wire connector, but most of these electrical components work the same.
Wire nuts, also called Screw Terminals, are a low voltage electricians best friend.
They are used to connect individual wires to each other and in fact can use them to join more than 2 wires. We use them, make them work, this way-
A.Turn off electrical power to the circuit on which you will be working.
B.Slice through the insulation on the ends of the two wires to be connected, using a utility knife. Remove about 1/2 inch of insulation from the end of each wire.
C. Place the wires parallel to each other.
D. .Twist the exposed wire ends 1 1/2 turns clockwise. Place the Wire Nut on the end of the twisted, exposed wires and turn clockwise to secure it. It should hold the wires together firmly and completely cover any exposed wiring.
F.Turn on the electrical power.
The finished joint should have no bare conductor visible, the wire nut should extend over the wire insulation.
