Note that some jurisdictions now require a neutral wire at each switch location, due to modern changes in switching technology that may require a neutral for a complete circuit, such as "smart switches". For simplicity, this article ignores such a requirement, as these "extra" neutral wires are simply run to each location and are not being switched. Connect the black wire coming from the breaker into the fixture location to the black wire going to the first 3-way switch.

This is the "supply" to the switching system. Use pliers to twist the exposed ends of the two black wires together. Complete the connection by screwing a properly sized wire nut onto the joint tightly.

Lightly tug on each wire to make sure they are both tightly connected. Wrap the wire nut connection with electrical tape for safety and durability. Repeat this wire connection process at each wire connection. Do not nick or skin the wires anywhere other than at the ends being connected. Connect the black wire coming from the fixture to a red or white wire that leads out of the box to the first 3-way switch box, and if using white identify the white wire with a color marking, such as red electrical tape.

This red wire is the one that will supply power to the light after traveling through all of the switches. It is the installer's choice whether to use the red wire or "white" wire identified with blue or other color as a traveler. This description uses the red wire as the "switched" wire from the furthest switch. The video uses a different technique to "carry" the white wire, as neutral, through each junction box, all the way to the remote light.

Part 3. Connect the black wire coming into the switch box to the "common" terminal on the first 3-way switch. Note that this black wire will always be "hot", regardless of the switch settings. Remove about 0. Use needle-nosed pliers to form a loop in the stripped wire. Do not overlap the wire with itself beneath the screw terminal. Repeat this wire connection process at each switch connection. If the switches have "back-wiring slots", as well as screw terminals, avoid using the back-wiring because it may be less reliable in the long run than the screw terminals.

Attach the red or red-identified white wire coming into the switch box to the red wire going to the next switch box, and eventually all the way to the final 3-way switch. Attach the black wire and white marked with blue wire going out of the box to the next switch to the bottom poles of the 3-way switch. These two wires are the "travelers" to the 4-way switch.

The third wire the red will not be switched at the 4-way location, but passes to the final 3-way switch. Note that a 3-conductor cable is often used for connecting 3-way and 4-way switches to each other, containing black, white and red conductors.

The white conductors should be marked to identify their function as travelers e. 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. Some 3-way switches may have the "common" terminal on one side and the two "travelers" on the opposite side.

Just make sure your black "hot" wire goes to the "common" terminal. Part 4. Attach the red wire entering the 4-way switch box from the first 3-way switch box to the red wire going to the next 4-way switch.

Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom. Look at the markings on yours and read the instructions carefully. If you are adding more 4-way switches, repeat these steps with the two 3-conductor cables entering each 4-way switch location from the adjacent switches. Part 5. Attach the red wire entering last 3-way switch box to the common "com" pole of the 3-way switch.

Not all 3-way switches are designed the same way. Just make sure the traveler wires are not connected to the common pole of the switch.

Part 6. Perform final assembly of the switches and wiring into their boxes. 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. This is intended to reduce the risk of accidentally shorting things to the terminals. Double-check that all connections are proper before carefully packing the wiring and switches back into each switch box.

Screw the switches into their boxes, being careful not to nick or pinch any wires. Test all of the switches. There are 8 possible combinations, when using three switches on and off.

Pick one of the four posts of the 4-way switch to hook up the source power. Put one lead of the multimeter on this post. Test the other posts to see which one has continuity and which does not.

Leave the lead on a post that does not have continuity with your initial post. Now flip the switch. Does it have continuity now? All you have to do is use two posts of your 4-way switch that alternate continuity when you flip the switch. That's all a regular switch is doing, breaking the continuity between your source power and your load.

A green or bare wire is the grounding wire, and it should be attached to a ground pole of each switch, usually a green screw, and to each box when using a metal box. Bare wires should be twisted together and wire-capped to provide grounding continuity to all switch locations.

Some local codes may not allow the use of non-metallic-sheathed cables other than in single-family dwellings.

Make no assumptions that "the power is off" until you have proven that it is off in those specific wires. Avoid using any white wires for anything other than "neutral" unless you have marked both ends of it with a distinctive color e. Anyone later looking at your work should not be confused about an unidentified white wire being a grounded neutral as opposed to being a switched traveler that may become "hot".

Each installation is different. Do not assume you understand the existing fixture or switch wiring unless you have studied it carefully and can document the function of each wire. How to.
