If your air conditioner is 120V but the outlet is 240V can you convert from 240V to 120V and how?

If the 220V circuit is dedicated, is to derate the circuit to a dedicated 110V outlet. Replace the 220V breaker with a 110V breaker and install a 110V outlet in place of the 220V outlet. If the original circuit was 20A or greater go with a 20A breaker and a 20A outlet as Airconditioners are fairly large loads. Do not exceed the current rating of the old circuit as that is all the current the existing wiring can handle.

You cannot use 2-120v outlets to power a 240v dryer. You can convert a 240v dryer outlet to power 2-120v outlets if they are supplied with a neutral. This requires a competent electrician. Do not do this yourself.

If you need to ask, you should have someone who knows how do it....

Yes, but you will only get one quarter of the wattage from the heater.

No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V

If I understand your question, Can you run a 110 appliance off of a 220 volt outlet? You could by only using one leg of the 220. You may also consider changing the outlet. Put in a regular 110 outlet and capping off one leg of the 220 in the wall box. You still have a neutral and a ground to work with. I read this as the questioner doesn't want to modify the outlet. Check the voltage ratings on the device. Many electronic devices nowadays can havdle 120V or 240V as it is cheaper to manufacture one powersupply and sell it everywhere. If your device is rated for 240V, you can put a 240V plug on it. If it only says 120V, no dice. 240V will burn it up.

lamp go "POOF!" It may be very bright, but not for very long!

Not only will it work, but it will last for much longer than if it was connected to 220volts!

You can using a transformer, but you won't have as many amps available. 5000 watt generator @ 120v = 41.66 amps 5000 watts / 240v = 20.83 amps

You really cant do it because a 220 has a heating element in it to dry the clothes unlike gas that uses fire to dry the clothes and the 120 is to turn the drum.Your drier will keep poppin breakers which isn't good at all.Outlets and Power(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.You can't, you need both a and b phases. You need to install an 240v receptacle.And don't upgrade to 240V by using the same wires!! Some complete idiots will try this and burn the neighborhood down.

The whites are Neutrals or Grounds and the Red and Black are each 120v. One white and either the black or red for 120v and one white, both the red and black for 240v.

It can't be "converted", you have to run a 220 line and have a 220 breaker and plug installed.

Chances are there is more than 1 outlet connected to the 110volt circuit you are looking to convert. So therefore the easy answer is No. The 240volt dryer circuit must be a dedicated single circuit for the dryer only.

I assume its 120V already: so, yes, you'll have to wire for a 240V receptacle (240V uses 1 more current carrying wire than 120V). Even if there were enough wires at 120V you'd still need a larger size wire for the combo unit. An electric dryer is a beast with electrical current.

You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.

In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.

120v or 240v. 120v is one leg of the main panel, and 240 is two legs of the main panel. 120v is lights,outlets. 240v, dryer,stove.

Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180ยฐ out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.

For USA, Canada and countries running a 60 Hz supply service.1) An outlet for 240V is totally different from a regular 120V outlet. 2) The wiring for 240V is also much heavier than for 120V.3) The double pole circuit breaker necessary for 240V is different to the single pole breaker used for 120V.4) Anyway it is not clear why you would want to try to change a 240V outlet to a 120V type?5) If you could log in and add some more details below here so we knew your reasoning for wanting this change to take place, someone may be able to assist you much further.The reason why I need to do this is because there is only one 3-prong 240V outlet in the water heater closet feeding an inline water heater and I want to install an instant hot water recycling system which runs on 120v I so need the extra power outlet.If you want to keep the existing 240V water heater then you cannot add another outlet to the circuit, not even a 240V one, let alone a 120V one!The wiring and its circuit breaker is only rated to carry the current for one water heater and nothing else. If you add another appliance to the circuit you risk causing a house fire: the breaker may buzz but not trip so that the wiring gets hotter and hotter until something catches on fire!So, if you are planning to buy a new hot water recycling system it surely deserves to be installed safely and correctly?So why not, for your instant hot water recycling system, have a licensed electrician install a separate 120V circuit with the correct breaker, the correct-sized cable and the correct outlet near to the existing 240V outlet?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 JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

You DON'T! The washer needs to be on a separate dedicated circuit; 120v, 20 amps. The dryer needs to be on a 240 V, 30 amp dedicated circuit. Trying to do otherwise is unsafe.

If you properly connect a 3 conductor cable to a 4 prong twist lock plug end this can be done. You must be sure that the grounding conductor and neutral are connected to the right terminals. Then the hot conductor, probably black, will connect to only one of the hot terminals. It wouldn't matter which. In this configuration you have 120v supplied from a 240v twist lock outlet and the cable can be connected to anything that requires just 3 conductors and 120v.
