How to Install a Wall Outlet in a Three-Way Switch Circuit
Bare wires should be twisted together and wire-capped to provide grounding continuity to all switch locations. Cut off the loop on the end of this wire. In any case, the traveler wires will be colored the same to distinguish them from the common. This is often easiest with needle-nose pliers.
Put the cover plate in place. This third wire allows power to run to your second switch even if the first one is off. If a larger load is to be connected, the appropriately larger sized wire and circuit breaker or fuse must be installed instead. Over time, these pressure connections fatigue and eventually fail, smokers weed so the use of screw terminals is preferable. The biggest difference between switch types is found in the screw terminals.
- The light fixture's box should have only a black wire, a white wire and a ground wire to supply power to the fixture.
- To learn alternate wiring methods and how to ground the switches, read more!
- The cable should also have a ground wire, or a total of four wires in the cable.
- If you have existing switches that stop working, they may be worn out or the terminal screws may have loosened over time.
- Test the other posts to see which one has continuity and which does not.

3 Way Switch Wiring Diagram
The black and red wires running between the switches are all used as travelers in this arrangement. Flip the switch toggle and check that you find continuity in one direction but not the other. Verify the circuit is wired correctly using the following guidelines. Move the second probe to the other terminal in its pair and test both arrangements again.
How to Hook Up a Home Light Switch
Look at the wires involved. Use the electronic stud finder to make sure that you will not be drilling or cutting into a wall stud. Become familiar with cable naming conventions.
The switches are wider than regular single-pole switches and they have three terminal screws on the side sometimes back of the switch housing. Both three-wire and two-wire cable with ground are used. The white neutral wire from the source is spliced at each switch box to run it through to the neutral on the light fixture.
Flip off power in the room you're working. All of the four terminals are brass colored. However, if all the existing ground wires connect to one bar and all the existing white wires connect to a different bar, maintaining separate ground and neutral connections is required. This is because the switch may turn the light on or off in either position, depending on the position of the other three-way switch in the pair. Some boxes have clamps to hold onto the wires.
- Article Info This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness.
- Connect the black insulated wire to the remaining unused terminal screw on the switch.
- Twist the two white, neutral wires together in each box and twist on a wire nut.
- The size of all the wires in any circuit must be the same size.
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. Replace the covers for the switches, screw them into place, and turn the power back on to be in business. Replace the drywall, coverings, dating a male high school etc. Check that the neutral from the source is only connected to the neutral terminal at the load. Only two-wire cable with ground is needed for the boxes at the lights.
Placement of the switches is the key to making these circuits work. Connect the two red insulated wires together with a wire nut. The ground wire is connected to the light fixture lead and is pigtailed to the box, if it is metal. It does not matter to which terminal screw this wire is connected.
Each installation is different. Then you'd connect the black power wire to one side of the switch and the black wire from the light to the other side of the switch and connect the white neutral wires together. 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 green is for the ground wire and the other two on either side are for the black hot wire. Click each additional switch to make sure each switch can independently turn the light on and off.
White - This is a neutral wire paired with the black. Attach the black power cable from the wall to the general screw black in the three-way light switch. Note that wiring configurations can vary greatly depending on how the circuit is arranged. Before you even start wiring, you want to get the fixtures securely in place so that you can effectively wire everything together. Most codes dictate that all wire connections must be placed inside a switch, receptacle or junction box.
If the switch box is metal, it also must be pigtailed to the grounding wires. 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. Connect feed wires in the first switch box. When working with electricity, dating sites for under have first aid instructions and protocols handy. Loop it around the screw and fasten it down like any other cable.
After making all your connections, fold the wires neatly into the box. Screw the switches into their boxes, being careful not to nick or pinch any wires. At any given moment when the light fixture is on, the power may be flowing through either the black or the red traveler wire. Based in Colorado Springs, Colo.

At the second switch box location, the wiring is similar to the first switch, with the traveler terminals connected to the traveler wires coming from the first switch. Make sure you use the power wire. 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.
Hook the curled end of the wire under the screw, then tighten down the screw to hold the wire firmly in place. You'll hook this around a screw, which you then tighten to clamp down the wire to the light switch. Curve the ends of every black and red cable into small hooks. End-of-Run Lights Controlled by Two Three-Way Switches These end-of-run lights are controlled by two three-way switches with a two-wire cable power source coming through the first three-way switch.
Also, always turn the main power off before installing a switch! Connect all ground wires to grounding terminals on all boxes and devices. Red - This is a switch wire or traveller wire, used to carry current inside the switch.

Install plates and covers. The black wire running to the light is used to connect the common from the dimmer to the hot terminal on the light. Click the next switch to turn off the light. Use a continuity tester or multimeter on the Ohms setting to determine if it's conducting electricity properly. Grounding screws often are furnished with boxes and are green.
