Replacing a defective 3-way switch... (The graphic above will help you understand the text below... and visa versa!) National code says a maximum of 8 openings per circuit. This might seem intimidating, but it does not have to be. If you can find the outlet box with the disconnected wire from the 3- way switch using a voltmeter (or ask your brother ) this box would be the easiest to control from the 3-way switches. A 2 wire feed is pulled from the nearest source of power like a receptacle or the panel to the switch. The power source is via the switch box SB1 and a 3-wire cable (C1) runs from there to the first fixture (F1). Hopefully your brother left it disconnected in one of the outlet boxes. But these color schematics are subject to change depending on your country. The first way of wiring uses a couple of Two-Way Light Switches with a 3-wire control. 1. Pick the diagram that is most like the scenario you are in and see if you can wire your switch! Be sure to provide GFCI protection as required. All you need are basic tools and wiring knowledge. NOTE: If your 3-way circuit uses an outlet or outlets instead of light fixtures, you might get confused with the wiring if the outlets are "split"... one of the plugs is always on and the other is controlled by the wall switch. The correct wire MUST be connected to the common screw of a 3-way switch otherwise the switches will not control the light fixtures correctly! Level Beginner Description Power (a hot and a neutral) is fed to the switch with 1 switch leg run from the switch to 1 light. One light switch is one opening, even if you have multiple light fixtures. It depends on exactly what you mean. You can get 'how to' books on this and other home repair subjects. Turn off the power source. In your switch box, you will see two white wires joined with a wire connector. The extra wire is necessary for the 2-way switch to work. 3-Way Switch wiring diagram depicting all wires in the ceiling junction Box. Fully explained wiring instructions and wiring diagrams can be found here in the 3 Way Switch area here in this website. You can use what are called 2-way switches. The following is the simple schematic of a three wire 2-way switch wiring. Run 12-gauge, 2-conductor electrical cable from the first of the two three-way switches to the power source. To add outlets and lights, you'll need a junction box and wire nuts. (Shown in the white box is a simple diagram that depicts the function of the three-way switch.) The neutral could be white or black. Just replace the light fixtures with outlets. Click the icons below to get our NEC ® compliant Electrical Calc Elite or Electric Toolkit, available for Android and iOS. The total voltage in a series circuit equals the sum of the voltage drops, which means if you have something plugged into each of the receptacles, the voltage of the series outlet at the end would be too low to do anything useful. Standard 2 Way Switch Wiring. Alternatively, you can wire the switch up in such a way that only that single outlet will be controlled by the switch, but other outlets in the circuit will still stay powered on constantly. At each switch in the above 3-way switch wiring diagram the black wire gets connected to the common copper or black screw. Before you start installing, take a look at your new 3-way switch to identify all of the terminals that you will be connecting wires to. 2 wire meaning; either 14/2 with ground (wg) for 15 amp circuits or 12/2wg for 20 amp circuits.
