How to Wire a Three

common terminal on 3 way switch

In the case of a typical 3-way switch, the black screw is usually used for the hot lead. On a single pole single throw there is no common terminal. A picture's worth a thousand words; see below. First of all we need to go over a little basic terminology on switches. Check local regulations for restrictions and permit requirements before beginning electrical work.

It may be brass, in which case it will be labeled or marked in some way as common. That's just not the way it's supposed to be, is it? The black wire that doesn't go into the same outer insulation conduit as the red wire is the hot lead to the light. Examine the loose wires which you disconnected from the switch there should be two black and one red. In this circuit, the source hot is connected to the common terminal on the 3 way switch in the first box. It may be a different colored screw usually black, while the others are brass colored , or there may be a stamping on the side or back of the switch - look carefully. Pull these wires out of the box and separate them so there is no bare copper touching any other metal. Once you identify the bad switch, follow the steps below to verify it is bad and needs to be replaced.

Sometimes, a 3-way circuit doesn't work because someone tried to replace a defective switch and did not properly connect the wires. This device can be used in place of any of the 3 way switches in these circuits, as well as Instead of terminals, a 3 way dimmer has 4 wires coming out of the casing: one common, two travelers, and one ground wire. In relays thisis known as a C form configuration. Countless homes across the country are plagued by miswired 3-way circuits causing not only inconvenience but a genuine safety hazard. Well, you must not have connected the common wire to the common terminal! For example, a circuit with 4 switches controlling one fixture. Touch the other probe each of the three wires. And of course the neutral will always go directly to the load.

Wiring a 3

Have another person stand at one switch, while you stand at the other. Because of this, the switch may also require a neutral wire. If it does, it is a good switch. Wiring Diagram 3 Way Switch with Light at the End In this diagram, the electrical source is at the first switch and the light is located at the end of the circuit. The live wire is your panel hot; remember it. On this page are several wiring diagrams that can be used to map 3 way lighting circuits depending on the location of the source in relation to the switches and lights. After the lighting level has been set on one dimmer, the other switch will turn the lights off and on at that level.

The internals of the three way switch does all the work. Find the labels Internal Connection in the diagram above. Remove the two 3- way switches so you can access the switch terminals. The first two graphics show the metal strip or tab. Three-Way This is a switch that has three terminals screws on it, excluding the ground screw if present. Ground, Earth This terminal will typically be green, and will likely be either at the top of the bottom of the switch. In the 2nd diagram below, blue wires are used for travelers.

The hot wire leading from the 3-way switch circuit will have no power, since all power must travel through the switches. With this arrangement, the switches control power to the ceiling box and a pull chain is used to control fan speed. In any case, the common terminal will be distinguished from the travelers in some way. Neutral The neutral terminal on a smart switch will often be silver, and is used to connect a circuit neutral wire to the switch. In this diagram, the source is in the middle of the circuit along with the dimmer switch.

Put a piece of tape on the wire that goes to the common terminal screw. If you're like me, then swap the red and black wires of the traveler pair, connecting the black wire to the opposite traveler terminal from the one you used on the first switch. White wires can, from time to time, be used as ungrounded hot wires though they're supposed to be marked when they are. On a single pole double throw it is the terminal that is common to both the top and bottom terminals. The electrician may have marked a wire by using electrical tape on the insulation of one of the wires near the ends.
