If a larger load is to be connected, the appropriately larger sized wire and circuit breaker or fuse must be installed instead. Connect the ground wire to the circuit ground wire s with a wire nut or other approved connection see How to Connect Electrical Wire. If the switch or junction box is metal, it too must be securely grounded with a green ground screw or approved grounding clip.
Head to your fuse box and make sure there is no power coming to the room you're currently working in. The neutral wire is white. Article Info This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Twist the two white, dating neutral wires together in each box and twist on a wire nut. Connect the two red insulated wires together with a wire nut.
Install A Three-Way Switch
- It does not matter to which terminal screw this wire is connected.
- Be sure to obtain any required electrical permits before beginning work.
- First, connect all ground wires as previously described.
- This way, you will ensure all connections are made properly.
Keep twisting until the wires are secured and the nut stays in place when let go. Connect feed wires in the first switch box. Select the proper wire size.
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. You'll hook this around a screw, which you then tighten to clamp down the wire to the light switch. Hook the curled end of the wire under the screw, then tighten down the screw to hold the wire firmly in place. This switch works in combination with two three-way switches to control electricity to lights and receptacles from three locations.
3 Way Switch Wiring Diagram
It is advisable to use No. No ground connection is made to plastic, fiber or another non-conductive box. After making all your connections, fold the wires neatly into the box. The power is routed first through the light ceiling box and then flows to the switches.

The ground wire is pigtailed with a wire connector at the switch boxes and the ceiling box. Current electrical codes require any switch box without built-in clamps to have the wires secured within eight inches of the box. Check all wire nuts for tightness and exposed neutral and hot conductor surfaces.
Over time, these pressure connections fatigue and eventually fail, so the use of screw terminals is preferable. Additionally, the wire should wrap clockwise around the screw. White or neutral wire taped with black electrician's tape is used as black power wire to make connections throughout.
Stranded wire will require fork or ring terminals to be installed crimped or soldered on the wire and the terminal screw tightened down on the fork or ring terminal. If equipped with a separate ground bar, rather than connecting to the neutral terminal bar, what to get a girl the ground wire can connect to the ground terminal bar. Make sure you use the power wire.
Grounding wires are pigtailed to the light fixture boxes, and to the switch box terminals. Armored cable types are very similar with only slight variations. Second switch is an end-wired or end-of-run switch.
The ground wire is pigtailed throughout. When remodeling, always check the fuse or circuit breaker on which new lights or outlets are being installed. Replace the drywall, coverings, etc. Never mix wire sizes or materials copper and aluminum.

How to Hook Up a Home Light Switch
Neutral wire bypasses first three-way switch. See color key in each figure. Connect the black insulated wire to the remaining unused terminal screw on the switch. Replace the covers for the switches, screw them into place, and turn the power back on to be in business.
Installing A 3-way Switch With Wiring Diagrams
Cut the cable to length if there is extra once you pull through the second box. Attach the hanging ground wire the pigtail to the green grounding screw. The ground wire should be connected to the neutral terminal bar. Remember to turn off the power before you do any electrical work.
- Grounding screws often are furnished with boxes and are green.
- 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.
- This extra grounding wire will be attached to the light switches.
- Curve the ends of every black and red cable into small hooks.
- Two grounding wires, plus one pigtail, tied off by a wire nut.
Choose a direction that will make it easy for you to then thread the wire towards your second switch box. This will make them easier to attach to the actual switches. Even when taped black, the white wire may never be used to bring power to the fixture terminal.
The light fixture's box should have only a black wire, a white wire and a ground wire to supply power to the fixture. You'll only have three screws. Become familiar with cable naming conventions. Upload a picture for other readers to see.

Flip off power in the room you're working. Not all switches are made for three-way wiring. It is not, however, authorized for use in all installations, such as being embedded in concrete or where exposed to the risk of physical damage.
