Answer for USA, Canada and countries running a 60 Hz supply service.You can't, you have to install a separate 240 volt circuit breaker and run a new 240 volt cable of the correct size from the breaker box or fuse box panel to the location where you want to use the 240 volt appliance.

<><><>

By asking this question you probably aren't quite ready to take on this particular task.

That you asked this question here shows that you don't already know your local Wiring Codes or Regulations so don't know how to calculate the correct wire size to use for the length of run from circuit breaker to power outlet.

Really, don't do this one yourself. Electricity is far too dangerous to handle if you don't already know your local Wiring Codes or Regulations or you have not been trained how to do this work.

For your safety - and that of anyone else who may use the 240 volt appliance - ask a professional licensed electrician to advise you or to do the work for you.

<><><>

How to do this job depends entirely on the Wiring Codes or Regulations for the locality (Town/State) and on the exact location of the appliance you wish to hook up: if it is in any place subject to water splashes or spray - such as in any room supplied with running water pipes, like a kitchen, bathroom, shower room, etc., or in a pool-side area - the codes specify that special precautions must be taken.

Depending on where your home is, it may be illegal to attempt to do this kind of work unless you are already a licensed electrician.

<><><>

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.

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

In the US, standard household receptacles are 120V, but historically they used to be called 110V. So the two are the same thing - at least in the US.

Depending on the age of the electrical device the nameplate may say:

110v

115v

117v

120v

and they all are referring to a standard household receptacle.

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU. Before an explanation of how to do it you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 240 volt receptacles and if you plug any 120 volt device into them, the 120 volt device will be destroyed. That said OK, any 120 volt outlet can be changed to 240 volt by removing the 120 volt circuits neutral, re identifying the white wire with red or black phase tape and connecting it to a new 2 pole 15 amp breaker. The maximum that this circuit will now load up to is, on #14 wire at 80% = 12 amps at 240 volts. The 120V receptacle must be changed to a 15A - 240V receptacle so that 120 volt devices can not be plugged into it. Never use 2 single pole breakers together because code requires that on a fault trip both legs of the 240V circuit must be disconnected simultaneously.

How do you know if 110v device can be used in 120v outlet?

110V and 120V are essentially the same thing--don't worry about that. 50 Hz vs. 60 Hz is more important, for some devices. North America is 60 Hz; much of the rest of the world is 50 Hz.


120V gas Kenmore dryer and the hook up location has the big 240V female receptacle--what is easiest solution thanks?

The easiest solution is to leave the 220V original outlet alone and plug the 110V dryer into a close 110V outlet, most likely the one for the washer. There should be nearby 110V outlets so you don't have to muck with rewiring the 220V outlet. A short heavy-duty extension cord is an option. I would also recommend killing the power to the old dryer outlet if it is unused. It cannot hurt. If you cannot plug the dryer into a nearby 110V outlet you can derate the 220V outlet down to a dedicated 110V outlet. This is not a task to be taken lightly if you are not experienced. If you do take this course of action yourself, buy a book. Do it right or don't do it at all. Negligence could kill someone.

Should be ok provided you do not draw too much current.

This is a two part question. Can a 110v outlet be converted into a 220v outlet, yes it can. The other part of the question needs to be discussed.

Is it possible to hook up a 240V dryer to a 120V outlet via some sort of power converter?

No. You need to have a 220 outlet. Your 110 has only 1/2 the voltage you need. Also, the question you ask is not really feasible. The wattage required by the heating elements is more than what a 110V line could handle. (110V outlets and 120V outlets are practically the same for this discussion. I will refer to them as 120V. Same with 220V/240V outlets.) By 110V outlet I'm assuming you mean a standard US 120V 15A outlet. This outlet can provide a maximum of 15A at 120V. This means the outlet can provide 1,800W of power. ( Volts x Amps = Watts ) This is the maximum amount of power this outlet can provide, no more. Also, this is assuming nothing else is drawing power off the circuit this outlet is on. If you try to pull 1800W from an outlet and plug anything else into this circuit, the breaker will blow. Your dryer is designed to run off a 30A 240V circuit. Let's say, for argument, it draws 24A at 240V. This means your appliance requires 5,760W of power to run correctly. This is 3.2 times the absolute maximum amount of power your 120V outlet can provide. There is no way you can run this appliance off this outlet. You have a larger problem here than the voltage difference. NO WAY One person has said "homes are not wired 110v, they are wired 220v. if you put a 2 pole breaker (or 2 pole fuse, if it's a fuse panel) in the panel, you will get 220v." Although it may be partly true, it does not answer the question. The related questions explore the amount of power needed for a dryer, which cannot usually be supplied through the wiring for a 110 V outlet. So, in general, the answer is no. You will need to run a different set of wires from the breaker/fuse panel to the location where the dryer is to be installed, and use a 2-pole breaker and the proper dryer outlet. You could, in theory, but the transformer would weigh more than the dryer and cost at least 4 times as much as a new dryer. The circuit would also have to be upgraded to at least a 60 amp 120volt outlet. Very impractical.


How can you wire a 110V plug outlet from a 240V plug outlet not speaking of a converter but actually changing the plug outlet so that there are no long term effects on the 120V appliance?

Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.


Can you use your dryer outlet for 120 v with an adapter?

Yes. The outlet on the stove should be rated to 15A 110V.


If the electrical device says 100-240 v is it safe to plug a 110 device into a 220 outlet?

Only if it is rated for 110V-220V. If it is rated for 110V only and you plug it into a 220V outlet, your device will be destroyed.
