Answer for USA, Canada and countries running a 60 Hz supply service.
The three switches can be wired for 120 volts by using any combination of the red and white or black and white wires from the three wire cable. Keep in mind that if the three wire cable is #14 wire the cable is only rated at 15 amps. Knowing the loads that are connected to the switches will determine what combination needs to be used. If the loads are small enough all three switches can be used on either the red or black which will leave you a spare feeder for something else. If all three switches are in a three gang box, use your selected feeder with three pigtails wire nutted to it. These three pig tails will go to the top screw on the three individual switches. The three loads will connect to the bottom screw on the three individual switches.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
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).
Can extractor fan be wired together with light switch?
Yes, an extractor fan can be wired together with a light switch so that they both turn on and off simultaneously. This setup is common in bathrooms where the fan is typically activated along with the light to help with ventilation. It is important to follow electrical codes and guidelines when doing any wiring work.
You have three 3-way switches operating 3 ceiling lights you want each switch to operate each single light What do you do?
To have each switch operate a single light, a 3-way switch must be installed for each light. Each switch needs to be wired to its respective light, with one wire running between the switch and light fixture. This way, each switch will control the light it's connected to independently of the others.
Why wont your downstairs light switch work when its turned off by upstairs switch?
It's because they are not wired in a 3-way fashion. The switch downstairs is wired in series with the switch upstairs in the same manner the pullchain on a light socket adapter would turn on and off your light only when the wall's switch is on.
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.
If you have a light and one switch that controls it what are the light and the switch wired in?
A light controlled by a switch are necessarily wired in "series", meaning that the electricity must pass through all components if the circuit is to operate correctly, assuming you actually have a source of electricity wired in as well.
What is the wire diagram for a light switch?
A wire diagram for a light switch shows the connections between the switch and the electrical wires in a building. It illustrates how the switch is wired to control the flow of electricity to the light fixture.
How is the power wired in a 3-way switch setup where the power source is located at the light fixture?
In a 3-way switch setup with the power source at the light fixture, the power is wired from the circuit breaker to the light fixture, then to the first switch, and finally to the second switch. This creates a loop that allows the switches to control the light fixture from different locations.
How do you install a dimmer to a light installed with W wire B wire and ground W running into the switch box if the switch box has power from B wire W wire and ground?
If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
How do you know that house lights are wired?
When you turn the light switch to the up (on) position, if the bulb is not burned out, the light bulb will glow.
Is it still within code to run power from panel to light switch then to light?
You can either go to switch or to light first. I wired house for my brother ran power supply from junction box then to each switch then to light. Passed inspection no problem
How do you ad and extra switch and light to the same 2 by 4 box?
There are multiple ways to wire a switch. If power is fed into the switch box, a second light would be wired one way, if power is fed into the light box, the second light would be wired a different way. This seems like it would be a task better given to a qualified electrician or local handyman.
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).

Where is the parking light relay located on a 90 Honda Civic?
There is no relay. They are wired directly to the headlight switch.
Is a stop switch wired in series?
A stop switch is wired in series with the power supply and the load.
Why on a 99 Chev Lumina are high mount brake light working signals and 4ways but not brake lights?
probably your blinker switch (multi-accessory switch). The high mount brake light is wired directly from the switch on the pedal but the rear two lights are wired through the pedal switch and then through the the blinker switch on the steering column. Almost all of those blinker switches go bad.
