Take all three ends and hold them together, then twist on the wire nut so they are all securely fastened together. For example, they can be arranged so that the feed cable runs to the first three-way switch, then to the light fixture box, then to the second three-way switch. In the following illustrations, track each wire with a finger or pencil to its conclusion at the fixture. Secure to the center of the stud, in the wall, so that it will not be hit by drywall studs later on if you were to hang anything near the light. Check all wire nuts for tightness and exposed neutral and hot conductor surfaces.
How to Hook Up a 3 Way Switch
Note that the shadings of the wires in the illustrations represent actual color. The cable should also have a ground wire, or a total of four wires in the cable. In order to code the white wire, which is used as a power wire from the light fixture through the switches, black electrician's tape is wrapped around the wire in the boxes. The neutral wire is white.
This will make them easier to attach to the actual switches. Grounding screws on switches were not always required, so if you are replacing an old three-way switch, you may find one without the grounding screw. The black or hot wire is routed to a switch and then is fed back through the connections via a white wire taped with black electrician's tape to indicate that it is hot.

Click here to share your story. See below for descriptions and uses of common cable types. Cables lacking a green insulated wire use the outer metal jacket as the ground conductor. Two grounding wires, plus one pigtail, tied off by a wire nut. Neutral wire bypasses first three-way switch.
3 Way Switch Wiring Diagram
Yes, but it's probably better to replace it with a regular, single-pole switch. Then, attach the green ground wire to the switch and the box, and attach the red wire to the third terminal. Already answered Not a question Bad question Other.
Additionally, the wire should wrap clockwise around the screw. Track each with a finger to its conclusion at the light fixture to ensure proper connection. Use wire nuts to attach the each set of two white wires together. Understand non-metallic cables.
Can t I just connect two regular light switches to each other
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. Most codes dictate that all wire connections must be placed inside a switch, receptacle or junction box. Grounding screws often are furnished with boxes and are green. The ground wire is connected to the light fixture lead and is pigtailed to the box, girls if it is metal. Choose a direction that will make it easy for you to then thread the wire towards your second switch box.
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. Before you even start wiring, you want to get the fixtures securely in place so that you can effectively wire everything together. Connect the two red insulated wires together with a wire nut. Connect the red insulated wire to one of the two unused terminal screws it does not matter which. If you run across an older switch without a grounding screw, it should be replaced with a newer, grounded switch.
Hook the curled end of the wire under the screw, then tighten down the screw to hold the wire firmly in place. Curve the ends of every black and red cable into small hooks. You'll hook this around a screw, which you then tighten to clamp down the wire to the light switch. The two lighter, brass-colored screws are called the traveler screws. Screw your two boxes and light fixture into place, then gather your supplies.
Not to worry, you can purchase and oversize receptacle box just for such an occasion. The red traveller switch wire runs just between the two switches, red flags when dating not the light. The red wire then goes with the other three to connect both switches.
There are three screw terminals on the body of the switch, in addition to the green grounding screw. All wire is utilized this way without waste. Take your time, mark the wires properly and you will not only be successful, you will stay sane. Some light fixtures with a chain pull have a ground connection.
The light fixture's box should have only a black wire, a white wire and a ground wire to supply power to the fixture. Wall switches used to control ceiling light fixtures or other fixtures come in three types. If the switch box is metal, it also must be pigtailed to the grounding wires. For example, relevant magazine christian 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.
Understanding Three-Way Wall Switches
Four-way switches have four terminals. This switch works in combination with two three-way switches to control electricity to lights and receptacles from three locations. There is no way we can anticipate every situation and we do our best to inform of any risks for each job.
Understanding Three-Way Wall Switches
- Attach the hanging ground wire the pigtail to the green grounding screw.
- The black and white wires follow this path, as does the ground wire.
- Cookies make wikiHow better.
- The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing.
- Again, connect all ground wires as previously described, if not already completed.
Be sure to check local building codes for proper installation and permits. The red traveller wire is connected to the third terminal on both switches and runs between them only, not to the fuse box or the light. Either way, the directions are the same. Be sure the circuit is completely dead!
Help wiring a 3 way switch
Note that wiring configurations can vary greatly depending on how the circuit is arranged. Loop it around the screw and fasten it down like any other cable. When the toggles are in opposite positions, the circuit is interrupted and the light fixture turns off. Do this by threading a special green, hex-headed grounding machine screw into a pre-tapped hole in the metal box, or use a special green ground clip.
- Both three-wire and two-wire cable with ground are used.
- First, connect all ground wires as previously described.
- If not marked, the common terminal may be color-coded black or brass.
- The white neutral wire is not connected to it it is typically just wire-nutted in the box.
- This extra grounding wire will be attached to the light switches.
- Connect the black insulated wire to the shunt or common terminal screw of the switch once again, the common screw terminal is the different colored screw from the rest of those on the switch.
