4-wire dimmer switch diagram

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.

Why do I have 4 wires on my light switch?

If two switches can control the same light, they are called “three-way switches” (go figure) and they need three wires. If you want to have more than two switches control the light, you use switches that have four wires (“four-way switches”, IIRC).

Is there such thing as a 4 way dimmer switch?

4 Way Smart dimmer Switch kit by Martin Jerry | 4-Way Solution to dim LED Lights at Three Different Locations.

How many wires do I need for a dimmer switch?

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.

How do you wire 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.

What is the red wire for 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.

What is 4 wire electrical wire used for?

Why Use 4 Wire Cable? A very common application of 4 wire cable is to provide both line-to-line 240V and line-to-neutral 120V AC power to appliances such as electric dryers and stoves.

Can I connect red and black wires together?

Can I Connect Red And Black Wires Together? Yes, it is sometimes feasible to connect a red and black wire together for a variety of reasons such as connecting smoke detectors, wiring back to a switch, a 3-way switch circuit, and other reasons.

Does the red wire connect to black or white?

To wire a light fixture, you need to know the wire colors and the corresponding voltage. The red wire should be connected to the black wire from the house circuit and the white or yellow wire from the light fixture. The third wire can be either bare, green, or blue.

Does Lutron make a 4-way dimmer?

Lutron Claro 15 Amp On/Off 4-Way Switch, CA-4PS-WH, White - Dimmer Switches - Amazon.com.

What is the difference between a three-way and four way switch?

A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.

How does a 4-way switch work?

There are four terminals that provide two sets of toggle positions on a 4-way switch. Each set of terminals is one of the toggle positions. When the switch is in the up position, the current can flow through two terminals. In the down position, the current flows through the other two terminals.

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.

What is L1 and L2 on a dimmer switch?

Dimmers look slightly different to standard switches being much more chunky. They usually come supplied with a common(C), Line out(L1) and Line out(L2) terminals similarly to a two way switch. Sometimes all three terminals are in a row.

Do dimmer switches need more wires?

Dimmer switches don't need special wiring at all. Single-pole dimmer switches can just replace existing single-pole light switches, and 3-way dimmers can easily replace a standard 3-way switch or be used as a single-pole switch with one wire capped off.

Why does my three way switch have four wires?

A 3-way switch has 4 wires because there is a 2nd switch controlling the voltage. Two wires are incoming voltage, and the other 2 wires are out going voltage to the 2nd switch.

What is the difference between 3 wire and 4 wire?

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.

Why do you tie the neutral and ground together?

If you touch the casing, and some real ground (like a water pipe) at the same time, you will close the circuit and carry all of the current. So, connecting the ground to neutral totally defeats the purpose of having a ground, and actually makes it more dangerous than not having the ground at all.

What are the colored wires for dimmer switch?

The wires from the dimmer will typically be black. The two house wires may be black, red or white with black marking. Tighten a wire nut over each pair of wire ends. If there is bare wire exposed, unscrew the wire connector, remove the wires, trim the ends of the wires with a wire cutter and then re-cap the wires.

Which color wires go together?

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.
