3 way light switch hook up, electrical made easy
Electrical Made Easy
The first thing you will need to determine is where the power is coming from and where the switches are positioned. Loop it around the screw and fasten it down like any other cable. They consist of a metal jacket formed by an interlocking, helically wound band of steel or aluminum around two or more insulated wires - including one white, one black, and often one green. After making all your connections, fold the wires neatly into the box. Check out of dimmer, way light switch or more common screw terminals.
Perform final assembly of the switches and wiring into their boxes. Next, connect the white wire coming into the box to the white wire on the fixture. Connect the two red insulated wires together with a wire nut. Radiant screwless wall box a night light can be the same light switch es could be afraid hook and switches installed for high-speed connected to. The other two screw terminals on the switch body usually are brass-colored and are used to connect the circuit wires that run between the two three-way switches.
Put the cover plate in place. The white wires tie light with a three nut. Each cable must also be installed and supported according to the standards of the local electrical code. The two lighter, brass-colored screws are called the traveler screws. All switches have screws on the side, but some also come with push-fitting holes or slots to slide the wire into.
In a circuit situation, the walking dead the traveler wires typically will have black and red insulation. Many electricians use electrical tape to make a final wrap or two around each switch to cover the screw terminals prior to installing the switches into their boxes. It should also help in way the functions of each type of switch. Use the electronic stud finder to make sure that you will not be drilling or cutting into a wall stud. Make sure you purchase accordingly.
This extra grounding wire will be attached to the light switches. After you restore power to the circuit, click a switch up or down to turn on the light. For example, you might want to be able to turn your main living room light on or off from beside your front door and also from the hallway to the bedrooms. Hey, doing it yourself is great but if you are unsure of the advice given or the methods in which to job is done, don't do it.
Attach the hanging ground wire the pigtail to the green hook screw. Remember to turn off the power before you do any electrical work. The white conductors should be marked to identify their function as travelers e.
Hook must be done at each and every box that a cable enters and at each device that provides a termination point for ground. Disconnect the black wire from the dark colored screw on the switch by loosening the terminal screw. Turn off the circuit breaker protecting the light switch circuit that you will be tapping into. If you have a multimeter, use the continuity setting.
Check to make sure that the power is off and the circuit is safe to work on by bringing the non-contact voltage tester near the switch cover plate. Take your power wire, coming from the house, and slide it into the first switch box. And of course the how will always hook directly to the load. The ground wire goes through both switch boxes and the ceiling light box and it is connected at all junctions, except the light, with a pigtail short piece of wire and wire connector. The ground wire is pigtailed throughout.
Understanding Three-Way Electrical Switches
Cut off the loop on the end of this wire. Note there are slight differences with the wiring at the light fixtures. Finish removing the cutout with the jigsaw or keyhole saw.

Other installers prefer to use two-wire cables from each switch to the next, purely for the travelers, and to run the hot or switched hot a different route to and from the fixture. Just make sure the traveler wires are not connected to the common pole of the switch. These screws, often gold, will be on opposite sides of the switch. Loop it around the screw and hook it down like any other cable. Hook the red one up to the side with you black power wire, and the black on the identical screw on the other side of the switch.
This way, if you or someone else goes into the boxes for repairs, the white wire taped black will indicate a hot wire. Both three-wire and two-wire cable with ground are used. Attach the appropriate hook to your light fixture. Alternative to install a light in order to add turn off. Use the long-nose pliers to make loops in the end of stripped ends of these wire as well as the bare, copper ground wire.
Hook the how end of the wire under the screw, then switch down the screw to hold the wire firmly wiring place. The cable should also have a ground wire, or a total of four wires in the cable. Upload a picture for other readers to see. Even when taped black, dating the white wire may never be used to bring power to the fixture terminal. Do not connect more than one wire under a screw terminal.
The size of all the wires in any circuit must be the same size. The three-way switch is a variation of the standard single-pole switch, which controls a light only from one location. Armored cable types are very similar with only slight variations.

- The system also requires three-way switches.
- It is advisable to use No.
- Screw the switches into their boxes, being careful not to nick or pinch any wires.
The light fixture's box should have only a black wire, a white wire and a ground wire to supply power to the fixture. Mark both ends of this wire by wrapping it with black electrical tape to alert others working on the circuit later that it is no longer neutral. Current electrical codes require any switch box without built-in clamps to have the wires secured within eight inches of the box. Additionally, the wire should wrap clockwise around the screw. Select the proper cable type.

- This screw is usually in the upper left side of the switch and is painted black, but check the guide that comes with your switch if you're unsure.
- Install the switch in the box.

Wiring a 3-Way Switch
Be sure to mark the white wire as noted so if any future repairs or replacement is needed, whoever goes into the box will know it is marked as a hot wire. Warnings Check you local wiring rules, as your local wiring system may use a different color combination. First, the body of the switch will be thicker and bulkier than that of a single-pole switch.
This is often easiest with needle-nose pliers. Some local codes may not allow the use of non-metallic-sheathed cables other than in single-family dwellings. Turn off that circuit breaker.
Help wiring a 3 way switch
The ground wire is connected to the light fixture lead and is pigtailed to the box, if it is metal. When both toggles are up or both are down, the circuit is complete and the light fixture will be illuminated. Three way switches have become very popular because it adds convenience and ease to lighting in large rooms, hallways and staircases.
