Leviton Trimatron Rotary Dimmer 6602-i Lot Of 50 - Answered Questions & Fixed issues

Typically in three way residential switching the Red and White are used as travelers from 3 way to 3 way. That in mind, connect the black to black, red to one red and the other red to the white. mark the white wire with black tape.

most likely the type of lamps/bulbs you have are not compatible with the dimmers.

hook a black to a black and the white to the other black. What they did there is called reverse feed, they pulled power from light box down to switch on one wire and send it back on the other wire. hook it up like that and it should work

Yes, but one of the outputs (runners) will remain unused. If your switch has pigtail wires (rather than screw terminals) the unused one will be live when the switch is off. Be sure to put a wire nut on the spare wire to insulate the end of it.

The switch has two black wires, One for Hot (black) in and out. The white is neutral (white) and needs to be tied to the load (socket, light, fan... ect.) after the switch. The green is earth (ground) and needs to be attached to you electrical box (the metal backing box)This is not my picture, i just grabbed it from google.

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.

seems like you have wiring for a three way switch you need a three way switch to make it work , the way i do it is the black and white are hot red is a traveler wirewhite will be onb top the others on bottom there should be a screw on top two screws on the bottom see if the white is tag with a peice of black tape on it to tell you the wire is hot, good luck

The best thing you can do in that situation is match the wire colors of the dimmer to the colors of the screw terminals on the switch you removed. Unfortunately, its too late for that - so here's my best guess: One of the black wires in the box will be coming from the same romex cable as the red wire. Take THAT black box wire and connect it to one of the red wires on the dimmer. Take the red box wire and connect it to the remaining red wire on the dimmer. Connect the black dimmer wire to the remaining black wire in the box. The two white connectors in the box get tied together - they don't get tied to the dimmer. And the ground (green) wire on the dimmer just connects to the bare ground connection in the box itself - or to the metal backbox - or cut it off and don't use it.

Is the dimmer rating higher than the load? Are you trying to dim fluorescent lamps? A flourescent requires special dimmer switch.

If you over loaded or mis-wired a transistor or wire wound dimmer, you may have damaged it.

Is this a three way light circuit?

Not really worth it at this point, just replace the dimmer.

Rotary dimmers have 2 black wires, and the color-code tells electrician that both blacks are interchangeable.
This means that dimmer is for single pole only. That dimmer will not work for 3-way switching where more than 1 'switch' controls same Load (light fan motor)
Connect either black dimmer wire to the red, and connect other black dimmer wire to the black.

For a price, expert works with you while you work on circuit or any do-it-yourself project.
Fixya is always less expensive than a service call.

The circuit you are working on is a 3-location circuit - where two of the devices were 3-way switches, and the remaining device (the one you are trying to replace with a dimmer) is a 4-way switch. Standard dimmers like the one you're using CAN NOT be used to replace a 4-way location. If you wanted to use it to replace either of the 3-way switches, that's no problem - but what you're doing right now will not work.

If you absolutely want to dim the lights from that specific electrical box, my suggestion is to upgrade to a "smart dimmer" where instead of a basic dimmer and two light switches, you have three devices that talk to one another and all dim the lights together.

In terms of your ground wire questions - ground wires certainly aren't necessary to make the whole thing work - rather they're there for safety. Sometimes installers will ground the device by connecting the ground wire to the backbox (assuming its metal) and then rely on the mounting screws on the dimmer or switch to perform the grounding. There are some code rules/exceptions for allowing the device to not be grounded (usually when its in a plastic, non-combustible backbox). If you want to make sure everything is completely up to code (which are usually goverened by local municipalities), you should consult a licensed electrician - but above all else, just use good judgement. Long story short, if the devices weren't grounded before, you can't make it any worse.

not you cannot...the switch is not rated to handle the cicuit load, it is only designed to handle the load of a lighting circuit, and you will overload it, and either blow the circuit breaker(or fuse) or worse catch the wires on fire Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

i want two dimmer switch parrel they both fhave two black and one green how fo you wire it up

That sounds correct to me. They are AC devices and your meter is a DC device. Try hooking it in series with a line cord and a lamp and see if it works. Be sure you do this in a safe environment electricity can kill.
Good Luck,

There are a possible two problems you might have. First a quick explanation of 3-way systems. If you have a common 3-way system, one switch box will have the "Power End" and the other switch box will have a "Switch Leg" end (the wire that goes to the actual light fixture. Then inbetween the two boxes there will be two (usually red / black ) "travelers" that connect to the switch. http://www.electrical-res.com/EX/10-19-02/3-way-switch-wiring-diagram.jpg Here is a link to a standard 3-way system. In the picture, the switch on the left is the "power end" and the switch on the right is the "switch leg" end. the first thing to do is establish whether you are in the "power" or "switchleg" box. You can do this by completely disconnecting the dimmer, then test which wire has power using a voltage meter. (do not use a "hot stick"! the tester that beeps or lights up when it senses voltage. These can give you a false reading) Once you know which wire has power, go to the other switch and flip it. If the same wire still has power, then you are in the "Power" side of the 3-way, IF A DIFFERENT WIRE HAS POWER NOW, YOU ARE AT THE "SWITCH LEG" side of the 3-way. The most frequent mistake made while installing a 3-way switch is getting the common and travelers mixed up. If you are in the "Power end", the "common" (or connection to your dimmers black wire) should be the wire that had power no matter which position the other switch is in. If you are in the "switchleg" box, the "common" or black wire from the dimmer should connect to the third wire that DID NOT HAVE POWER no matter which position the other switch was in.
The second (and less common) mistake with 3-way systems and dimmers is that certain dimmers are REQUIRED to be on either the power or switchleg side to work properly. If this is required it should be stated in the instructions!. Good luck and feel free to reply if you're still having trouble getting it going.

If the dimmer has two leads, it is a standard dimmer. One wire brings power into the dimmer, the other lead send "dimmed" power out.
If the dimmer has three leads, it is a 3-way, which is a combination of a dimmer and a 3-way switch. One wire brings power into the dimmer, and the other two leads bring "dimmed" power out - when you cycle the on-off function (by clicking the switch) you are sending the "dimmed" power out one lead or the other. You can use a 3-way dimmer in place of a standard 2-way by simply not using one of the 2 wires coming out of the switch. BUT you must be certain to insulate the end of the lead you aren't using, because when the switch is "OFF", this unused lead will be live. If you are actually trying to wire a 3-way, here's an excellent how-to-- http://www.ehow.com/how_2280970_wire-threeway-dimmer-switch.html Please vote if you found this helpful. Thanks, Al

You cannot, at least not using the dimmer you have in your hand. The switch with all the wires is a four-way switch, which is used to make a "suicided" 3-way switch. The power comes in AND goes out to the light from that switch. The other switch is a 3-way. Neither one has the "ON" or "OFF" marks on them, do they? You can buy a 3-way dimmer, but i do not know if rotary-style 3-way switches exist. You will have to install the dimmer at the other switch because i am quite certain no 4-way dimmers are available.

When you take the existing switch out of the wall, the existing switch will have one black screw and two gold screws. The wire that is connected to the black screw of the existing switch (probably on of the black wires from the box) connects to the black wire on the new dimmer. The other two wires (one black and one red from the box) that are connected to the two gold screws on the existing switch will connect to the two red wires on the new dimmer. Basically, wire from black screw goes to new black wire and wires from gold screws go to new red wires.

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.
