I would like to install a Lutron 3 way dimmer switch. The switch has a red, black, green, and white/red striped wires. The previous switch has 2 red and 2 black wires connected to it. The other 2 light switch locations had 2 black wires and 1 red wire. I have a few questions: 1. How do I install the 3 way dimmer switch 2. I changed the light switch on the other 2 locations, but they previously did not have a ground wire. Should it? 3. It doesn't look like the 3rd location has a ground wire either because there isn't a wire connected to the ground wire screw on the existing switch. Should there be?

you should be able to by hooking up the black wire on the dimmer to the hot wire(that comes from the electrical panel) in the wall box and the red wire from dimmer to the switch leg(the wire that goes to light fixture). if the dimmer has a white wire(nuetral wire) you will need to hook that up to the white wires in the wall box....CAUTION!!! when removing the old 1 pole switch, there should only be 2 wires and possibly a green or bare copper ground wire attached to it. if either of the 2 wires(not the ground) are white, IT IS MISLABLED OR MISCOLORED. DO NOT hook the dimmers white wire to it cuz it will fry the dimmer. If this is the case, then most likley you do not have a nuetral in the wall box but look anyway for a couple of white wires tied together with a wire nut and stuffed in the back of the box. if you find those than most likely thats your neutral(check with a wiggy or meter to be sure) and thats where the dimmers white wire goes. hook up the dimmers green wire to a green or bare copper wire in the wall box and then put a wire nut on the dimmers red w/white stripe wire.

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.

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:

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.

This is single-pole -or- 3-way dimmer
Manual shows on following link:
http://www.lutron.com/TechnicalDocumentLibrary/0301107A.pdf

1) Manual says: The red/white wire is not used in a single-pole application. Twist a wire
nut over this wire for a single-pole application.
2) Green wire connects to bare ground wire. Or bare ground to bare ground.
3) Connect dimmer-red and dimmer-black to either insulated wire that came off of old switch

Lutron Dimmer manuals
http://www.lutron.com/Service-Support/Technical/InstallationInstructions/Pages/InstallationInstructions.aspx?syst=Dimmers+%26+Switches&prodn=Maestro%C2%AE+dimmer+%26+switch

Lutron manuals show a couple things that might be affecting you lights.
1) Wattage: If you have wrong wattage dimmer
2) Type of light bulb: Dimmers work on different types of bulbs
3) Wiring: You say you got 3 wires going to the chandelier? Why you got 3 wires? Is this a 3 way switch? Are the chandelier bulbs wired separately so you can control groups of bulbs with different switches?
Does the dimmer have 3 screws? A dark-colored screw and 2 brass screws? If so, then that sounds like a 3-way dimmer. A 3-way, is where more than one switch controls the same light.

Does the dimmer have 2 screws? Then that dimmer controls a single circuit. Your black Hot wire from breaker box connects to one screw and the black wire to Load connects to other screw.
A quick glance at Lutron wiring manual shows that Hot and Load wires connect to either screw.
The question is your 3-wires from the chandelier ... does the black Hot wire from breaker arrive in the ceiling box first? Or does it arrive in the wall box first? If your Hot arrives in ceiling box, then the Hot must come down to the switch box and connect to a screw on the dimmer >>> a second wire connects to other screw on dimmer and travels up to the ceiling box where it connects to black wire on chandelier. The white wire on chandelier connects to white Neutral.
4) Dimmer might be bad

If I understand correctly, you have Leviton florescent dimmer

And you want to connect dimmer to Lutron ECO-series ballast

This is the ballast with 3 wires: Hot dimmed, Neutral and Hot


Is this your dimmer???? Has Black, White, Red, Yellow-red, & Orange




Here's how to do it:
Dimmer yellow-red is not used except for 3-way switch >> cap it off with wire nut
Dimmer orange wire connects to ballast Dimmed Hot
Dimmer red wire connects to ballast Hot
Dimmer white wire connects to ballast Neutral

Those are your wires going to ballast. As you can see, you need 3 wires going to florescent fixture

Next, let's focus on Dimmer:
Dimmer green wire goes to bare ground wire
Dimmer black wire connects to Hot from breaker box (we'll test for that next)
Finally the Dimmer white wire connects to ballast Neutral as discussed above BUT is also has to connect to Neutral from breaker box

This means the Dimmer white wire is connected to 2 wires >> one wire goes to florescent fixture and the other wire comes from breaker box


So which wires come from breaker box??
It should be a black and white wire.
Let's test to find Hot and Neutral that come from breaker box.

Mark your wires.
Disconnect all the wires and separate from each other
Turn on power
Use ordinary tester
Tape tester leads to wood sticks so hands stay away from electricity
Power is on
Test each wire to bare copper wire
When tester lights up, that is Hot from breaker box ... this wire connects to Dimmer black wire
Now, test the hot wire to each of the other wires
When tester lights up, that is Neutral wire ... this wire connects to Dimmer white wire, and also connects to Ballast neutral.

Connect one wire at a time, and it will work.

The dimmer connections should go like this.

Black from dimmer to black Constant Power In Wall
White from dimmer to Neutral (Whites) in wall
Yellow from dimmer to wire out to light (usually black)
Green from dimmer to BARE GROUND WIRE

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.

You have to have a special ballast on the light to dim fluorescent light fixtures. You also have to have a special dimmer.
