What are the 3 wires on a dimmer switch?





Single pole switches will have 3 wires: a hot lead wire, a ground wire, and a traveler wire. Older homes may only have a hot lead and a ground wire. If you have less than three wires, stop and call an electrician.

What is the red and white wire on a Lutron dimmer switch?

Red is the switched lead (or a traveler in a 3-way installation), and is attached to the switched hot going to the light. Red with white is a traveler, used for 3-way installations. In your situation, you’ll just cap this one off. Green is ground, and is attached to the grounding conductor.

How do you wire a 3-way Lutron dimmer switch?

Quote from the video:
Quote from Youtube video: First connect the green wire of the dimmer to the ground wire in the wall with the yellow wire nut provided in the packaging. The ground wire will be bare copper or green in color.

Why does my dimmer switch have 4 wires?

Since the switch cuts the power on and off, there will be a black wire coming into the switch and a black wire leaving. The whites are normally just connected together with a wire nut and the coppers are connected together with a wire nut or grounded to a metal junction box. So the new switch has four wires.

How do you connect dimmer wires?





Quote from the video:
Quote from Youtube video: You'll also have a bare copper ground wire connect the ground wire to the green ground on the dimmer switch by twisting the two together and screwing on a wire nut.

What is the common wire on a dimmer switch?

Your new dimmer switch then gets wired the same way as the previous switch, i.e. black(hot) to black and the wire marked common, white or neutral to home’s white(common) wire. Twist wires together using a wire-nut.

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

Quote from the video:
Quote from Youtube video: And take a tester and see which one of the black wires is a live wire. So this is our live wire this is going to be our common terminal. Now if you try both of these black wires.

Do you need a neutral wire for a dimmer switch?

If the light is off, without a neutral you won’t have a complete circuit to power the smart dimmer circuitry.

Where does the red wire go on a dimmer switch?



The dimmer switch has a ground wire, a red wire, a black wire, and a striped red wire. According to the instructions on the dimmer the black wire should be connected to power; the red wire should go out to the light; the striped red wire should just be capped; and the ground should go to the ground.

How do I identify a neutral wire?

Quote from the video:
Quote from Youtube video: You have a neutral if the two controlled wires are white and black look in the box.

How many wires does a dimmer switch have?

Attach the Dimmer Switch



There will be three wires: one black, one white, and a separate ground wire that may be bare copper or is sometimes wrapped in green.

Do dimmers need 4 wires?

Things You’ll Need



Wiring a three-way dimmer switch uses four wires and allows you the convenience of dimming the light from separate switches at opposite ends of a room.

How do you connect 4 wires to 3 wires?

Connect the ground wire of the 3-wire cable to the ground wire of the 4-wire cable. Connect the black wire of the 3-wire circuit to either the red or the black wire of the 4-wire circuit. The red and black wires are the”hot” wires. Either wire can be used to power a circuit.

Which color wires go together?

See Table below. The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.



US AC power circuit wiring color codes.

What is the 4th wire for?



The 4th wire in that cord and plug configuration is an equipment grounding conductor. This equipment grounding conductor is the missing wire in the older 3-wire configurations. In these older appliance installations where 3-wire cords were legally installed, the wiring consisted of two hot wires and a neutral wire.

Does the red wire connect to black or white?

Attach the black wire to the outlet you want to always be on (usually the top one) and the red wire to the switched outlet. Connect the white wire to either of the chrome screws (remember, they are still joined) and the ground wire to the green ground screw.

Can I put the red and black wires together?

These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.

What do I connect the red wire to?

Normally you’ll see a red wire in places you would expect a ceiling fan. But in places like a bathroom or a wall light, if you see a red wire, it’s a good bet that the red wire is the wire that’s connected to the light switch.
