Take off one of the dimmer wires and whatever wires or bundle of wires you have goes to one of the terminals of the regular switch. If it is 2 or more wires then marrette them together first with a piece of wire 6 or 8 inches long to wire to the switch terminal. Then remove the second wire from the dimmer and handle it the same way. (if it is a single conductor then just put it on the switch screw by itself)

SOURCE: 1 way and 3 way dimmer switches

The answer to your question depends on the manufacturer and type of 3 way dimmer you are using... generally you can use a 3 way switch as a single pole switch, but whether or not this holds true with the dimmer you are using depends. Let me know what you are trying to acomplish and model numbers mfgs of what you have and I'll try and help

For a single-pole installation:

1. Connect the 2 white wires together (one from the source and the other to/from the light fixture) - 2 wires
2. Connect the black wire from the source to the black wire on the dimmer switch - 2 wires
3. Connect the black wire to/from the light fixture to the red wire on the dimmer switch - 2 wires
4. Connect the ground wires - 3 wires

In your wall box you should have two cables these wires are coming from. The cables are 3 wire w/ground so that you can use 2,3,and4 way switches in the house.

One cable is a line cable, the other is a load. In other words, there is one cable with incoming voltage, and the other cable is a follower, or a cable with wires to pass current along to the next wall switch.

The dimmers are very finicky. One good spark from touching the wrong wire will immediately short it out.

Without knowing whether you are in a 2 or 3 way switch situation it is impossible to accurately tell you which connect to what.

If I were you I would go to Lowes or Home Depot and buy a good wiring book (like Stanley) and go home and sit down and draw out your circuit.

Note that if these wires are for 2 or 3 way switches it changes things. But that book should help you identify it.

SOURCE: how do I install decora sureslide single pole dimmer switch??

Ok, first turn off power by finding the break box and switching to off. Then I'm assuming you mean by "socket" you mean the hole in electrical box mounted in or on your wall the dimmer is supposed to mount to. Sounds like your electrician ran the power back to the switch through your neutral/white wire. Your dimmer has a top and bottom, it also could possible have a tiny word imprinted that says "to light" and "+" if not attach the white from your socket to the top black wire on the dimmer, then connect bottom black wire to the socket's black wire...ground wires should connect to each other and to the ground in the wall socket. Use wire nuts to secure, then check to make sure no wires are touching anything except for what they are supposed to me touching...and test it before you permanently attach. Go switch power back on, and try your dimmer...if it works GREAT:) Now go turn off power one more time, tape your wire nuttted connections with electrical tape, mount dimmer and go turn back on the power. Hope this helped! Thanks

One wire is the common and the other two are the travelers.The trick is to find which one is which.... If you can see into the electrical box check to see if one of the red wires and the black wire are from the same cable, if they are then more than likely those two wires are the travelers; you can also look at the other switch and see which two wires are on the brass colored screws, those would also be travelers. The common is usually the wire that is on the black colored screw. Once you figure out which wire is your common, I'm thinking that it is one of your red wires, you would attach that wire to the black wire on the dimmer and the other two wires to the 2 red wires on your dimmer.

What do I do with the red wire on a Brinks Halogen Motion Sensing outdoor security light

Please perform these connections with the mains power off.

The standard is the Black wire is hot, the White wire is neutral, and the Red wire is switched. For your Sensor connection 120V is connected Black to Black and white to white while the Load is connected White to White and Black to Red (assuming your load is using standard color coding.
Here is a simple diagram for your connection.

with a three way switch like this, you will have two traveller wires and a common wire. Look in the instructions for the switch or on the back of the device itself to see if there is a wire labeled "common" or "com". This common wire from the old switch hooks up to the common wire on the new switch. I did a bit of searching on the leviton 6602, but couldn't find anything specifically about the three way version (I would venture to guess, however, that the red wire on the old switch is the common). The common on one of the three way switches will always be a constant hot (or power) wire...the common on the other three way switch will be the "switch leg" or the wire that connects directly to the light. The two travellers go to the other two wires. Check the pamplet that came with the lutron device, it should show which wire is common and which are travellers.

I installed a Lutron LG 603 P. I have existin three way wiring. Previous light switch operated fine as a three way. The new dimmer comes with two red wires and a black. My wiring is white, black &...

The correct way to wire this switch is the wire that was on the gold or dark colored screw of the old three way switch is called the shunt or common terminal. The wire connected to this terminal is to be connected to the black wire of the three way dimmer. The other two wires are connected to the silver or light colored terminals of the switch. These are the traveler terminals. The traveler wires may be connect to either traveler terminal - it does not matter which.

If you have already disconnected the old switch, simply connect the dimmer wires to the house wires as shown top to bottom in each configuration below until you get it to work as expected:

Config1 Config2 Config3

B R R B R R B R R Dimmer Wires: B = Black R= Red R = Red
R W B B R W W R B House Wires: R = Red W= White B= Black

In two configurations or less, you'll have found the correct wiring for the switch. I hope this helps & good luck! Please rate my reply. Thank you.

I am replacing an on-off switch, with the 90610-wv dimmer. The instructions says there should be 2 black wires, and possibly a green. The wire in the existing switch has 1 white 1 black, and a bare copper...

The important thing to remember is your switch has two wires.
Sometimes the colors vary a bit because of the specific circuit.
The green wire, when present, is a ground wire, and always connects to bare copper wire.

If your dimmer has two black wires, then connect dimmer-wires to either switch-wire
If the dimmer does not work, simply reverse the two wires.

If your dimmer has a red and black wire, then connect dimmer-black to switch-black, and dimmer-red to switch-white.
Again, if dimmer does not work, reverse the two wires.

Answer back if you have trouble, and I will help.

My girlfriend has a leviton illumatech IP106 that keeps "not working". after a number of months. It is operarting a standard dining room 6 light chandelier. A couple of her friends have replaced this in...

As a general rule for timers and dimmers:

The Black dimmer wire connects to black hot wire coming from breaker (122V line)
The red dimmer wire connects to Load (wire going to chandelier)

The wall red wire that is capped could be a couple different things. a) It could go to a second switch that was used to control the chandelier. b) it could be another wire that goes to same ceiling box as chandelier to be used to control a fan, except you don't have a fan. In the second case, if you install a fan with a light, you could control fan and light separately.

The green is a ground wire that connects to bare copper wire in box. The bare copper connect back to main breaker box on the Neutral busbar.
White wires that are twisted together inside your light switch box also connect back to to main breaker box on the Neutral busbar.
The ground wire and neutral are a redundant safety system to protect you from electrical devices and appliances that have 'shorted'
The black hot wire connects back to the circuit breaker.

For example, each circuit breaker controls one area of household lighting. The black white and copper wires leave breaker box in a single romex cable. The romex travels to a junction box in the area where the lights are located. The junction box is usually a switch box or a ceiling box. From the junction box, the romex travels to each other switch, light and receptacle box in the area. So each box has 1 hot and 1 neutral and 1 ground that is connected in a line that leads back to breaker box.

You bought a three-way switch, but that's OK you can use it. Connect green to green (that's the ground). Connect black to black (that's either your incoming or outgoing hot wire). Connect white to one of the reds (that's either your incoming or outgoing hot wire.) The other red wire will not be used BUT you must put a wire nut (and/or tape) on it to insulate the bare end, because if the black wire in the box is your incoming hot wire, then this extra wire on the switch will be hot when the switch is OFF.

How to install a dimmer switch

This is a 3-way switch, made to control a light fixture that is also controlled by another switch in a different location. A typical example is a ceiling light fixture installed in an upstairs hallway, which could be controlled by switches at both top and bottom of the staircase.

The green wire in your switch is the ground connection, and joins to the green insulated or bare copper ground wire in the switch box. The red wire is the common connection. It connects either to the incoming AC hot wire from the electric panel, or to the hot terminal of the light fixture, depending on the switch location. The two black wires are traveller connections. They connect to the traveller terminals of the other 3-way switch.

If you purchased this switch as a replacement for a regular single-pole toggle switch or dimmer switch - one that controls a light from a single location only - then this isn't what you need and you can't use it. You'll know if you have a single-pole switch because it will have only three wires or screw connections. Return it and get a single-pole.

To install this as a replacement for a 3-way toggle switch or dimmer, connect the red wire to the wire going to the common terminal of the original switch. This will be a black- or brass-colored screw on a toggle switch, or the different-colored (not green, that's ground) wire on a dimmer. The black wires connect to the wires that go to the traveller screws (copper-colored) on a toggle switch, or the same-colored wires on a dimmer. It doesn't matter which traveller wire connects to which.

Note that if you're using a 3-way dimmer, only one of the switches can be a dimmer. The other switch has to be a plain old 3-way toggle.

Ok the RED is Phase and the Black is Neutral... Green is Earth. you have an IN, Red wire, and an OUT Red wire, the rest just go color to color. So in the socket, one Red wire goes to one Red wire from the dimmer, the other Red wire in the socket, goes to the other Red from the dimmer, then Black to Black, and Green to Green. Be careful do NOT work on it live.

Can I get a schematic of this dimmer?

a three way dimmer has three wires on it. two are red one is black. the black is the common just like the odd colored screw on a standard three way switch. the two red wires go to the "travelers" to the other three way switch. standard wiring practices: hot goes to the odd screw, travelrs go to the other three way switch. at the remote the load comes off the other odd screw.
