Does the back of the power supply have a switch that can be set for 230 volts or 115 volts?
Some power supplies have a voltage selector switch at the back that can be set for either 230 volts or 115 volts depending on the region's power requirements. However, not all power supplies have this feature, and it is important to check the specifications of your specific power supply model to confirm if it has a voltage selector switch.

How do you changs a switch commutateur interruptor?
To change a switch, first turn off the power supply at the breaker. Remove the switch cover plate, unscrew the switch from the electrical box, disconnect the wires, and connect them to the new switch using wire nuts. Screw the new switch into place, replace the cover plate, and turn the power back on.
How do you install a doorbell with four wires both having black and red wires?
It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.
How do you wire a basic off switch to a light?
Light switch connection is usually straight forward. Find your incoming hot wires, black and white. With the switch in the off (down) position and the power disconnected , connect the black wire to the top screw of the switch. Find the load wires and connect the black to the bottom screw of the switch. Connect the two remaining white wires together with a wire nut and push them to the back of the switch box. Install the switch into the wall box, replace switch plate cover. Turn the breaker (power) back on. Flip the switch to the up position and the light should come on.
Where do you plug in the power cord in at?
The power cord should be plugged into the power outlet on the back or side of your device. Make sure to connect it securely to ensure proper power supply.
Why does some equipment only need a single pole switch while other equipment needs a double pole switch to operate?
Answer for USA, Canada and countries running a 60 Hz supply service.The type of switch is dependant upon what voltage the load uses. If a load is 120 volts, the electrical configuration is one hot line and one neutral. To break this load a single pole switch is used to break the one hot leg. Neutral wires are never to be opened. If the load is 240 volts, the electrical configuration is two hot legs. To break this load a double pole switch is needed to break both hot legs. A single pole switch will break the load but not safely. If you were to work on a 240 volt system with just one leg broken, the voltage from the second hot leg could feed back 120 volts to the ground. If you got between this voltage, a nasty shock could be given. So it for safety reasons that on 240 installations both lines are broken with a two pole switch.
Apple computer can run on 220V from 110V power supply?
No, of course not. The power supply needs to match the 'wall power' to provide the proper voltages to the motherboard. On the bright side, most power supplies sold in the US have a slide switch to select between 110/220 volts input. It may be as simple as moving a little red switch on the back of the power supply to configure your power supply to 110 v.
Does the back of the power supply have a switch that can be set for 220 volts?
Depending on the type of power supply you use. Heavy inear power supplies use a transformer that converts mains power to a lower voltage. They sometimes have a voltage selector switch that puts the two primary windings in series for 220 volts AC or in parallel for 120volts AC If it doesn't have a switch that controls the input voltage it might be a newer switch mode power supply that can automatically adjust for differing voltage inputs in different countries. The label should then say 80-240 volts AC input and say 12volts DC output. This can be plugged in straight away. Moving from the States to Europe requires you to get a voltage coverter of the right wattage from Tandy or CPC.co.uk.
Why would the system power on when the power switch in the back is flipped but does not boot until the front power button is pushed?
The switch on the back is the switch for the power supply only. The computer boots from the main power switch on the front. This particular method of switching was introduced with the ATX power supplies.
I have a SOny Viao PC bought used in the US at 110 volts. Am now living in Australia which runs at 220 volts. What switch at the back of PC do I turn on to run the computer?
The red switch by the power cord input.
If I buy a computer in Australia will it work in USA with a plug adapter?
No it won't. A voltage of (near) 230 volts and a frequency of 50 cycles per second is used in Europe, most of Asia, most of South America and Australia. BUT In North America, the most common combination is 120 volts and a frequency of 60 cycles. so you have to buy a 120v power supply.
How do you wire a disconnect switch?
To wire a disconnect switch, first turn off the power supply. Connect the incoming power wires to the switch terminals. Then, connect the outgoing wires to the load terminals. Finally, secure all connections and turn the power back on.
What are the voltages values that are produced by the power supply?
Depends on the power supply, usually theres a red switch on the back that says the voltages that I can be. You can also change them by going to the boot setting(setting when the computer boots up)
Can you use a PC bought in the US in UK?
Check the back; if the power supply has a switch that lets you select the voltage the PC can be used either in the US or Europe. If it DOESN'T have the switch, read the manufacturers literature to see what's required. you may need to replace the power supply, depending on what you have.

1995 buick regal no break lightsswitch is good and fuse is good?
Check for 12 volts at the hot side of the brake light switch. If you have 12 volts at that point depress the brake pedal and check for 12 volts at the cold side of the switch. If you have power there go to the back and check the bulbs, be sure they are good. If the bulbs check okay and the wiring looks good the problem may be in the signal switch under the steering wheel.
What is the effect on the supply current if the capacitor is removed?
It depends on how the capacitor is connected and whether the supply voltage is a.c. or d.c. Assuming you are talking about a power-factor improvement capacitor (connected in parallel with an inductive load, supplied with a.c.), then the supply current will reduce.
Can the power supply cause the computer to be difficult to turn on?
Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300. One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs. External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.
