There is a good chance that the green wire is your grounding wire. http://www.YouTube.com/watch?v=KNo78fMZfRI&feature=PlayList&p=05D94AD4BF05DD32&index=5&playnext=4&playnext_from=PL Attach black to black with connectors and ground (green) to ground (usually a white wire in the box).

What is a green switch?
A green switch is a switch that has been coloured to green for identification when it is among other switches.
How do you install a dimmer switch for multi fixtures where the original switch has 2 black wires and one red with no green?
This simple if you have two switches controlling a set of light you will need to buy a three way switch. A three way switch will have a place for three connection. Depending on what brand of switch you purchase the directions will be sightly different but most dimmer come with detailed directions and diagrams. When you by a dimmer you need to read what kind of load it is meant to control. They are built to control incandescent light, magnet low voltage lights or electronic lights.
Why does a dimmer switch have 2 red wires?
That could mean that it is for a 3 way application. Should have 2 red 1 black 1 green.
How do you wire a 3-way dimmer switch that has two red wires and one black and one green when the box has two red and two black?
you can only have one dimmer, the other switch needs to be not a dimmer. the green wire is ground, it connects to a bare copper wire found in the box, or to the box itself, if the box is metal. the black wire is"common" it either connects to the wire found in the box that has power in it or to the black wire that goes to the light. the 2 red wires are"travelers" they connect to the wires found in the box that go from switch to switch. if you don't know how to check which wire does what( continuity), it is possible to keep changinging the connections until the switch works. you will want to do this with a conventional switch, and install the dimmer afer you identify what wires are travelers and wich are common. you will destroy a dimmer switch by searching for the right connection. once you have identified the common wires, it will be on the black screw of a 3way switch; you can put that wire on the black wire of the dimmer. one red goes on one traveler, the other on another traveler. there might be a white wire in the box, if it is connected to other white wires and not to the switch, leave it alone. if a single white wire is connected to old switch, it may be a traveler.you will connect a red dimmer wire to this. opening the other switch location will show you if the white wire is used as a traveler.the black wire has to be either power coming in, or the wire going to the light. the reds are just connecting the 2 switches.
How can you activate the golden and green switches in boo's mansion in super Mario 63?
After you kill Boo, you have to find the green switch. This activates new green pieces that let you reach the orange switch. I haven't figured out what the orange switch does yet.
Installing sunpro tachometer to 1990 Nissan sentra dimmer switch which wire does the white wire connect to from tachometer to dimmer switch?
ok. the first thing u do is unplug the ignition coil and find a red and black wire and just kinda skin it and touch it when the car is on to see any movement and the dimmer switch pull it out and find a green and blackwire hook the white wire up to that and test the lights you know turn the head lights on everything else is instructions when you buy the tach.
What color is the on off switch on the narrow panel automatic regulator?
"b. Green." The Narrow Panel Automatic Regulator (NPAR) has three toggle switches. The "On / Off" switch is on the right, and it is green.

Dimmer switch that has one black wire connected to the left side and two black wires connected to the right side of the switch How do you connect these wires if you want to just install a regular flip?
Check the screws next to the wires and see what color they are if they are green, black, and red then do what i say next, if not you're screwd. just connect the red/black/green wires in the holes in the flip switch and be careful not to touch the wires just the protective covering and inert them they should auto lock in there...if not just screw them in.
If you have a switch wired red and black and a fan that calls for black and white where does the red wire go?
It sounds like your fan also has a light with it. If your wall switch is a two gang box with two switches in it most likely one switch is for the light on only and the other switch is for the fan on only. This can be checked out by installing the fan and making the connection green to green, white to white, black to black. Turn on one of the switches and see if the fan operates. Disconnect this connection and then connect the red wire to the black fan wire. Turn the other switch on. If the fan turns on again, then the two switches were installed to operate the fan and light separately. If this is the case disconnect the red and fan black wires and reconnect the black to black. This is the fan connection. Connect the red to blue fan wire and this is the light on the fan connection.
How do you replace a dimmer light switch with a regular light switch coming off of a wall plug ive got 2 black wires 2 white wires 2 grounds and one red wire going to the light?
This is a relatively simple wiring job. Remember that all a switch is, is a means of interrupting the power coming from source (electrical panel) and travelling to load (light fixture). Without the switch, the light would stay on constantly. The black wire is a power wire and so is the red. The white wire is a neutral wire, and the green wire is the ground. You may have to do some trial and error to get it right as I can't see the actual wiring diagram you have. After shutting power off to that circuit, disconnect the dimmer switch and remove. Connect the two white wires together with a wire connector. Connect the two green wires. The red wire was probably part of the dimmer switch and should now be gone, but if it isn't then just cap it off. Now connect the black wire from the fixture to one of the terminals on the switch, and connect the black wire from the electrical panel to the remaining terminal on the switch. That's it.
How do you install a dimmer switch black wire black wire and green wire to some existing black white wires?
First let's consider the existing wiring in the wall box: A Red wire can be the first "Hot Leg" of a 240 volt supply.A Black wire can be the second "Hot Leg" of a 240 volt supply or the "Hot" wire of a 120 Volt supply.A white wire is normally the "Neutral" wire. It is common to both hot legs on a 240 Volt supply.A Green wire (or bare wire with no insulation) is normally the local "Ground " wire. However, if, and ONLY if, there was an on/off switch for a 120 Volt lighting fixture installed onto that wall box before, it is possible that the red and black wires in this situation are:a) the "hot" feed wire coming from the mains breaker panel to the switch andb) the "switched hot" wire going to the lighting fixture.BE VERY CAREFUL TO BE SURE HOW TO DO ANY OF WHAT FOLLOWS SAFELY BEFORE YOU TRY TO TEST ANYTHING WHICH MAY BE A HOT OR LIVE WIRE: Only someone who knows how to use a test lamp or voltmeter safely would be able to confirm whether the red wire in the wall box is a) and the black wire is b), or if they were actually wired the other way round meaning the black wire in the wall box is a) and the red wire is b).If that is the case,AND YOU ARE ABSOLUTELY CERTAIN THERE IS NO 240 VOLTS MAINS SUPPLY INVOLVED IN THIS JOB,then all that is needed is to do the following: BE SURE TO SWITCH OFF THE MAINS SUPPLY AT THE MAIN BREAKER PANEL.TEST THAT NO WIRING IN THE WALL BOX IS LIVE USING A PROPER TEST LAMP OR VOLTMETER.Then connect one of the black wires on the dimmer to the red wire in the wall box and the other black wire on the dimmer to the black wire in the wall box - using proper insulated connectors of course.The green wire on the dimmer must be connected to the existing Ground wire, a green or bare wire in the wall box. If there isn't an existing Ground wire then you must fit one or have an electrician fit one for you because the dimmer may be unsafe to use without it! After you have checked that all the screws holding the wires in the various terminals in the insulated connectors and the wall box are tight, screw the dimmer to the wall box using its fixing screws. You can then switch on the mains supply at the main breaker panel and check that the dimmer operates to dim the lamp in the lighting fixture. Please refer to the Related Questions shown below for more information, expecially the requirement to check whether what you want to do - to install a new dimmer - will comply with the wiring code in your locality. (Town/state/country). If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
