3-Way Light Switch Wiring Edmond

Three basic types of light switches are available. The first is a single light switch which is easy. The second is a 3-way switch controlled from two locations by one lighting fixture. The third is a 4-way switch controlled from three or more locations by one lighting fixture.For three-way switches the easiest way is to place the light between the two switches. To comprehend, you need to take a close look at an electrical wiring diagram.The cable should be Romex 12.2 right up to the first switch, then run Romex 12.3 to the light then turn on to the second switch.The Romex 12.3 has an extra wire called a traveler (usually red), which is required for 3-way switches.The 12.2 Romex from the circuit run enters the bottom of the switch box at the first switch, and the hot (black) cable on the switch connects to the bottom right terminal.The Romex 12.3 enters via the top of the switch box. The (red) hot traveler wire connects to the switch at the top left terminal.Do you want to learn more? Visit Light Switch Wiring Edmond.

The black (hot) wire links with the connection at the top right terminal.The 12.3 neutral (white) wire directly connects with wire nuts to the 12.2 neutral wire, and the copper ground wires are also linked with wire nuts.You should be having two ends of 12.3 Romex hanging out at the light box. Each end comes from the first turn, the second switch comes from the other end.To get them out of the way, first connect the copper ground wires together with a wire nut, and then also connect the two red traveler wires with a wire nut.Now find the black wire that comes from the first box and the white wire that comes from the second box and connect them with wire nuts. Oh, that’s essential, by covering it with black electrical tape you need to mark each end of the white wire. This means you made it into a hot wire. That is a prerequisite for coding! 3 and 4-way switches are common practice.Now, you will be connecting the red traveler wire to the top left terminal at the second switch. The white, wire now labeled with tape as black, connects to the upper right terminal. The black wire connects to the terminal screw at the bottom right. If the package is rubber, the copper wire must bind to the box if it is a metal box or the green ground screw at the connection.Instead, the light box should have a black wire and a white wire poking out to attach the light to.
