Now if you were talking about controlling 20 lights from 5 controllers with remote control and timers and computer control, I'd say avoid X-10 like the plague, but for your installation, you will love it. I'm sorry, but I can't answer the question on 1977 code - it was before my time. All other white wires should be colored. Just keep adding more 4 way switches to the diagram, always between the two 3 way switches. As a licensed California Contractor, I thought I knew basic wiring. At the second 3-way switch, wire nut the two white wires together.

Be sure to check local building codes for proper installation and permits. These wires in our example the white wire from the light box to the switch box and from that box to the second switch box should be colored black or some other color , using a magic marker or some other method. At L2 this white wire connects directly to the neutral terminal on the light fixture. If one switch is up and one is down, the current reaches a dead end, no current flows and the bulb is off top left and bottom left. Proper electrical safety cannot be emphasized enough. If the light is off, press a button and the light will turn on.

Wiring A 3 Way Switch?

For this lesson, we'll explain how to wire up a light using two 3-way switches and one 4-way switch. Then it is necessary to understand a little more just how a three way switch works, and perhaps how to read and understand a wiring diagram. Good, because it may get bumpy. In this example the only neutral wires are the white wire in the power in cable which is always a white wire and one of the two wires attached to the light also always white. It is intended to provide future capability for the use of a dimmer or other device that may need a neutral wire and to put a stop to homeowners disconnecting or using the ground wire for purposes other than providing the necessary ground to switches or lights. For circuits with only two switches, just ignore the 4-way switches in the above figure. But, the amount of work and materials needed may be more trouble than your just pulling the needed extra wires.

The upper right screw gets the black wire from the left box 4-cond. With conduit, the wire colors for travelers could be any color. Good electrical safety practices dictate here that a voltmeter be used to double check that the circuit is actually off; either use a non-contact voltage detector or a volt meter with one probe to each of the side terminals one at a time while the other is touched to the green ground screw near one end of the switch. Any and all grounds in the same box are always to be tied together exceptions can be made for special computer circuit grounds. Some light fixtures with a chain pull have a ground connection.

It ties into the common on the left switch. End-Wired Switches: Power Through Light Power through the lights to three-way switches has two-wire cable and ground between the light boxes and three-wire cable and ground at the switches. Flipping the 4-way in the middle should turn it off or on as well. Here the source is in the middle of the circuit. Make sure that whenever doing any kind of electrical work that a good voltage detector is available - it can save a lot of grief. Toggle the right switch and it connects to the upper circuit and now closes the path and turns the light back on and so on. This is a reasonable method for cases with multiple switches in the same box, as other switches then have power available and can operate other lights without having to have a separate power in line run to them.

How to Wire a Light Switch

This way, if you or someone else goes into the boxes for repairs, the white wire taped black will indicate a hot wire. You should have a space for a neutral wire white , a grounding wire, orange or green and a power wire black. The power is routed first through the light ceiling box and then flows to the switches. The previous figure shows a circuit that follows this convention. At the lights the hot source is spliced to the black wire running between lights, it does not connect to the lights.

The red traveller switch wire runs just between the two switches, not the light. I am assuming here that one light is to be wired as in diagram 3. A, also wrap black tape around the white wire from the switch to the light. The same for a 20 amp circuit: 20 X. The most common way to wire a 3-way switch while want to light-up of your staircase or hallway. In any case, the traveler wires will usually be the same color to distinguish them from the common wire.

Then remove the light switch panel to see where the power is going. They don't connect to the light fixtures at any point. It does not terminate at any switch, although it may be present in a switch box and spliced straight through the box. Is the switch that is closest to the panel box on a three-way connection always identified as switch one? This circuit also shows rough-in boxes, wire nuts, and proper color code. Anyway, that track lighting blew up in 2013 when my sister was renting the unit from me, according to my sister I now live in the unit as owner-occupier.

The power source also connects the terminal main three-way switch and means that you need to have it spliced with a 3 way switch with the wire cable and that you will see the way that there is a neutral terminal with the light. Given that each one is to have a traveler wire attached to it, and there are two traveler wires and terminals, it doesn't matter which traveler wire goes to which traveler terminal. Power is coming from the fuse panel into the box with the first switch, call it 1A. Or is this a dangerous bad connection? If not, one of the wires is interchanged with the common going to the light fixture. This article explains a 3 way switch wiring diagram and step How to wire three way light switch electrical circuit We have to discuss about what are the three ways for wiring diagram as discussed below and how to connect all the lights and what are the different techniques to join such switches to getour own desired outputs as mentioned below. You want to zig-zag them, so they come about a bit like an accordion. Fixture Between Two Three-Way Switches: Power Through Switch Light is controlled by two three-way switches with the light between the switches and the power first going through a switch, then to the light, and onto the second three-way switch.
