Answer for USA, Canada and countries running a 60 Hz supply service.
To run your air conditioner you must run a new circuit for 240 volts including the correct size breakers, wiring and receptacle.
You can keep the existing 120 volt branch circuit and receptacle for other appliances.
<><><>
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 will happen when the shunt motor is connected across the supply line directly?
If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!
How many inventions did Willis Carrier make?
Willis Carrier invented the Air Conditioner, a few others.
How can you make music come on with a light switch?
You can make music come on with a light switch the same way you can make a light bulb come on - plug a radio into the switched outlet.
How many volts is there in a single phase?
The number of Volts in a residential service drop in the US is either 120V 2 Wire, 120V-208V Network, or 120-240V 3 Wire. A 120-208V Network service is not single phase, but its 120V portion is.
Should the person who installs your air conditioner have HVAC training?
The person who installs your air conditioner should definitely have HVAC training. You always have to make sure that the technicians, and the companies they work for are licensed. This give you some assurance that they are experienced and know what they are doing.
In hooking up a 240V Air Conditioner you have four wires but only three on outlet What three go on receptacle Red Black White Copper?
For a 240V with ground outlet you will connect black (hot) to one brass screw, red (hot) to the other brass screw, and bare (ground) to the green screw. Cap white (neutral) with a wire nut. It is for 240/120V appliances. If you don't fully understand this buy a book. This is a very basic question. If you don't understand which wire is which you could make a serious mistake causing fire or death.
If you have a 240V outlet for a window AC unit can you connect a switch to shut the outlet off?
Yes, just make sure it is a 220 volt switch.
Can a 30A 240V outlet be replaced by a 20A 240V one?
You can, but be advised that whatever you plug into the new outlet should not exceed 5000W capacity (20A x 250V = 5000W)or you could risk overheating the new outlet with serious results. To prevent this, you should make sure the circuit breaker is a 20A also.
If you do not have a 240v outlet for a washer and dryer can you work around this or does an electrician have to come and install a new outlet?
You will need an electrician. No. That dryer draws a maximum of 7200 Watts. The regular 120V outlets around your home can supply 1800W. So any type of converter will not work. If you have an electric range, the outlet for that is the only outlet in the apartment big enough for this. You can make an adapter if you really want to go down that road. How to do that has been answered a number of times on this site. Keep in mind this will involve pulling the oven out every Tim you want to do a load. If it is gas you are out of luck. Really you have two good options:1) Have the correct outlet installed. You shouldn't do this yourself for liability reasons (Burning down apartment complexes tends to be pricy.) Your landlord may install one for you if you are nice, and, more than likely, will let you have one installed if you pay for it. 2) Sell your old dryer and buy one that matches the hookups. You'll have to see which is fiscally wise.
Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?
Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.
How can you wire one half of a 20 amp 120 v duplex wall socket to run 240 volts over 2 legs 2 separate 120 v legs?
You can't. I'm not sure exactly what you're trying to do, but the way it is written is not possible. It seems you might want to use half of a duplex receptacle for 120 and half for 240. This would not be code compliant, nor would it make sense. A plug designed for 240v will not even fit into a 120v receptacle. You need a 240 volt receptacle rated for the amperage you will need. Also, an existing 120v receptacle has nothing to do with your 240v receptacle. For a 240 volt receptacle, you'll need to run 2 new 120v lines (in the same cable). The existing 120v circuit cannot be used here, even if you added another 120v circuit, because when a load uses 240v, both 120v circuits supplying the 240v must be controlled by a common disconnect (a 2 pole breaker designed for 240v circuit). My advice would be to show an electrician what you want done. I'm sure they can tell you how to make that happen.
Can you plug a CB radio into a standard wall outlet?
They do make base station CB radios, which run off of 120v AC power.
The cooling fan will not come on when you turn the air conditioner on?
Make sure unit is plugged into working outlet.
What countries use 240V?
Answer for USA, Canada and countries running a 60 Hertz supply service.The US runs 240V single phase in almost all residential applications.It just so happens that the 240V is center tapped to make 120V/240V split phase, but that is still a single phase application.For more information about the supply services in other countries, please see the answer to the Related Question shown below.
Can you take a 240v 20a garage outlet number 12 with 4 wires and split it into two 120v circuits while still keeping the 240v outlet?
for USA, Canada and countries using similar 60Hz mains suppliesI'm not sure if the National Electrical Code is okay with it, but it is possible. Make sure you have a 20 Amp Double Pole breaker in the panel. Then, at the 240V outlet: You may need more room to accomodate all the wiring, so get a box extension, or if possible, upgrade to a larger box or use a junction box before the 240V outlet. Okay, Take the incoming neutral wire and connect it to the 2 120V circuits and to the 240V outlet. Connect the incoming red hot wire to a black 120V hot wire. Connect the 240V Black hot wire to the other 120V's hot wire. Connect all the ground wires together. Make sure that the box is grounded as well. Here's a simple formula for calculating the current you can use. Remember that the 120V circuits take current from one leg or the other, while the 240V Circuit takes from both. Since you have 2 120V 20A circuits, multiply the amps of the equipment you can use by 1. Now, multiply the 240V equipment's amps by 2. Add the values together. The value should be less than 32, and definitely not higher than 40. I recommend installing a 120/240V twistlok plug in the box. Then you can plug whatever you want into it. I made a nice distribution panel with 15A breakers for when I want 120V, and 240 can plug in directly. ( I use this method to power my Christmas lights. 2kW. :P)IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.If there are only 3 wires entering the box, you can't legally do it. You can not use the same wire for a neutral and a protective ground. The 3 wires are the two hot phases and the protective ground.If there are 4 wires in the box, or if metal conduit provides the protective ground in addition to 3 wires, you can do it, provided the breaker is a double pole breaker. The white wire is the neutral, the bare one is the protective ground
Can you use 120V appliances on a 240V outlet?
Some appliances may work, but I imagine most would either blow a fuse or just burn out. Definately not advised unless you use a transformer. With the right transformer everything should work fine.
Is it possible to use a Dryer that has been bought in USA in India. India has a input power supply of 230v 50Hz. Dryer - MaytagPerforma Model PDET910AYW 3 WIRE 60Hz 120-240V 26A 5750 W?
It is important that you should read see the answer to the Related Question shown below: "Can you plug a US 240v 60Hz appliance into a European 230v 50Hz outlet?".No, sorry. Most US dryers have a 240V heater and a 120V timer and motor. While the heater will work fine, you don't have the 120V supply for the timer and motor. Also the timer will run slow on 50hz if it is not solid state (Most dryers still use motorized timers), as well as the drum turning slow, and the airflow being decreased.If you have a sufficiently large voltage converter you can make a neutral for it, but you have no way to know how much current the neutral pulls without testing or cracking it open.You may want to just sell it and buy an Indian dryer.
