Why does your garage light switch have 3 white 3 black wires 1 green and 1 red wire?
There are several possibilities, depending on the needs of the electrician who wired the light for you. In general, the wires are either power in or out of the box, and what is called a "switch leg". If you have questions about your specific application you should contact an electrician in your area to inspect the wiring and explain to you what it is for.

Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
How do you wire an additional light to another light with a switch?
In the wall switch box you should have a white and black pair from your source of power (120 volts). The other pair of black and white wires from the wall box should be going to the light fixture junction box. With the power off, connect the two white wires together with a wire nut. Connect the two bare copper ground wires together making sure that at least one of the ground wires goes under the green screw in the switch junction box. Turn the switch to the off position, no little indicator bump showing on the switch toggle lever. Now take the black incoming hot wire and put it under the top screw on the switch. Hot wires always go to the top of switches. Now put the black wire that is going to the light fixture under the bottom screw. Tighten both. Install the switch into the wall box with the switch handle in the down position. All switches when installed must be off in the down position. Install the switch plate cover.
How do you wire a light switch that has a black common screw and two gold screws one on each side of light switch and a green screw?
That is called a three way switch. It's used in conjunction with another 3 way switch in another area and they both control a light or set of lights. The black is power and the other two are called travelers that wire to the the other 2 gold screws on the other switch. A three way switch can be used as a single pole switch by using the black screw and one of the brass screws. You will have to test the circuit to orient the switch so up is on and down is off, if that is what you desire, because it is not obvious on a three way switch. The green screw is simply your equipment ground. You place your green or bare conductor there.
If there are two black and one white wire in ceiling light do I need to use both black for the switch to work?
If there are two black wires, it's possible that it was wired for a ceiling fan and that one of the wires is for the fan part while the other is for the light part. If so, one of the black wires may be switched while the other is always "on." Normally black is "hot" and white is "neutral" (NOT ground... ground is usually green).
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.

When at a 2 pole light switch and the wire colors shown are black white and green which is the hot wire and which is the common?
the black wire is the hot wire
How do you wire in a light switch?
To wire in a light switch, first turn off the power to the circuit. Then, connect the black wire from the power source to the brass screw on the switch, and the black wire from the light fixture to the other brass screw. Connect the white wires together and the ground wires to the green screw on the switch. Finally, secure the switch in place and turn the power back on to test the connection.
How do you hook up a light switch?
To hook up a light switch, first turn off the power to the circuit. Then, connect the black wire from the switch to the black wire from the power source, and the white wire to the white wire. Finally, connect the ground wire to the green screw on the switch. Secure the switch in place and turn the power back on to test the connection.
What is the purpose of the black screw on a light switch?
The black screw on a light switch is used to connect the hot wire, which carries the electrical current, to the switch. This allows the switch to control the flow of electricity to the light fixture.
Why is one the garage sensors yellow and the other is green?
The green light is the receiving end and the yellow light is the transmitter, when they are both aligned properly.
What color can you shine on green to make it black?
To make green appear black, shine red light on it. Green absorbs red light, so when red light is shone on green, the green will appear black.

Why green shirt looks black in red light?
When green light is mixed with red light, the colors combine and form black. This is known as subtractive color mixing, where red light subtracts the green color from the green shirt, resulting in it appearing black under red light.
What colour would red green and white appear if a green light was shone at them?
While the ball would still be green it will appear black. Anything green absorbed all colours except green. The green light is reflected to your eyes which makes it look green. Thus in red light (with no green in it) the red will be absorbed and no green light can be reflected to your eyes so the ball will look black.
