What color wires go on a 3 way switch?

Figure A: 3-Way Switch Wire Diagram — Power to Light Fixture The black hot wire connects to the far right switch's common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch's common terminal, leads back to the fixture.

What are the three wires on a 3 way switch?

But the “hot” or “charged” (usually black) wire coming from the power source connects to the switches. With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire.

How can I tell which wire is common on a 3 way switch?

What happens when a 3-way switch is wired wrong?

Usually when a 3-way switch fails, lights can be toggled on and off at one switch, but not the other. If one of the two 3-way switches toggles the light(s) on and off, the other 3-way switch has probably failed.

Is one wire always hot on a 3-way switch?

Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. It's also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.

Can a black wire be a traveler?

The cable run linking the two switches is made with 3-wire cable. The black and red wires are "travelers" and are connected to the traveler screw terminals on the two switches.

Do the travelers matter on a 3-way switch?

Easiest Way to Replace a 3-Way Switch Then, you can disconnect all three wires from the switch, as well as the ground wire. Because the other two wires (the travelers) are interchangeable, it doesn't matter which of the traveler screws you attach them to—there's no need to label them.

Why would a 3-way switch trip a breaker?
