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.

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.
Do ceiling fans have timers that turn the lights off after a certain period of time?
Not usually, The light would have had to been wired with a three wire from the switch to the fan. One circuit to control the fan and the other switch to control the light. If this is your situation then all you will have to do is change the light switch to a timer and that will do what you want.
New ceiling fixture goes on as soon as power is back even though switch is off?
You switched the power and switch wires. There should be two sets of wires in the ceiling box. 2 black, 2 white, 2 bare. Two groups of three. The white wire going to the light is the incoming wire. The black one in that group is the power coming in. Take that black wire and connect it to the other black wire. The second black wire goes to the switch. The power comes back to the light on the white wire of that set. Connect that white wire to the black wire in the fixture. The switch should work now. That is if everyone wired the house the way it is supposed to be.
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.
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 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.
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.
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.
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.
Can a bulb work as a switch?
First answer: No. Second answer: Yes. A light bulb is a resistance. Current flows across a tungsten filament, heating it to produce light. However, if there was some other resistance wired into a closed circuit, a screw type bulb could be used as a switch. You unscrew it to throw open the circuit, effectively turning off whatever else was wired in the line. Screw it back in to switch it on. So yes, you could use a light bulb as a switch. Some switches have LED (light emitting diodes) built into them so they light up when the switch is closed, and turn off when the switch is open. And some switches are wired just the opposite, so the LED is on when the switch is off. This makes these types of switches easier to find in the dark.
If you wired up the circuit with a bulb two batteries and a switch with a thin wire what will happen?
the bulb will light up
