Click Image or here to enlarge Diagram. No ground connection is made to plastic, fiber or another non-conductive box. 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. Cut the cable to length if there is extra once you pull through the second box. All wire is utilized this way without waste.
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. Connect wires in the light fixture's box.
Grounding screws often are furnished with boxes and are green. See color key in each figure. There are unique precautions and instructions for each type and special connectors for armored cables.
- When obtaining power from a nearby electrical outlet or another circuit device, the new wiring must be the same size as those that supply the outlet.
- Most light fixtures have two electrical wires with colored insulation and a copper ground wire.

Hook the curled end of the wire under the screw, then tighten down the screw to hold the wire firmly in place. 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.
Over time, these pressure connections fatigue and eventually fail, so the use of screw terminals is preferable. Second switch is an end-wired or end-of-run switch.

Use wire nuts to attach the each set of two white wires together. Light switch at one end, lights in the middle, light switch at the other end. Cables must be secured so that, if there is tugging or pulling further down the line, the live wires don't rip out of the box and cause issues. To ensure your safety, make sure you test the wires prior to attaching them to your switch with a voltage tester.
Use a voltage detector to ensure that you're not going to shock yourself once you start working. Looking for a Z-Wave Robot Vacuum? There is no way we can anticipate every situation and we do our best to inform of any risks for each job. Never mix wire sizes or materials copper and aluminum. Grounding wires are pigtailed to the light fixture boxes, and to the switch box terminals.

White - This is a neutral wire paired with the black. Be sure the circuit is completely dead! In fact, teacher I wired my whole home myself with no prior experience and I didn't get shocked even once.
- Option Two Three way switch with the power going through the light.
- Connect all ground wires as previously described, if not already completed.
- Take off the cover, and note the color of the wire insulation for the wires that connect to each side of the switch.
- Head to your fuse box and make sure there is no power coming to the room you're currently working in.
The white neutral wire is not connected to it it is typically just wire-nutted in the box. This will make them easier to attach to the actual switches.

All of the four terminals are brass colored. Two grounding wires, plus one pigtail, tied off by a wire nut. 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. Be sure to check local building codes for proper installation and permits.
With this knowledge, you or a family member can do the wiring connections for one or more lights. The red wire then goes with the other three to connect both switches. If the light can be turned on or off from switches at each side of the room, you'll see a blue wire that connects the electrical circuits for three-way switches. Trace the wires carefully in the diagram so you can connect them to the proper locations. Four-way switches have four terminals.
The ground wire should be connected to the neutral terminal bar. If a larger load is to be connected, the appropriately larger sized wire and circuit breaker or fuse must be installed instead. Be sure to obtain any required electrical permits before beginning work. Then, attach the green ground wire to the switch and the box, and attach the red wire to the third terminal.
The neutral wire is white. One of the black and white wires goes to the light fixture.
