When you talk about a 220 volt wire and 110 volt wire, the reference is to the insulation factor of the wire. The amount of amperage that the wire has a capacity to carry is independent to the amount of voltage that can be imposed on the wire. When you see wire with ratings of 300 volts, 600 volts and 1000 volts, these are the highest allowable voltages that can be impressed without going over the manufacturers recommendation of allowable voltages. A wire that is rated for 300 volts indicates that the wire is rated for 120 volts or 240 volts or 277 volts. At test research facilities, equipment is tested to destruction. The maximum voltage rating, that is given to the wire as a result of these tests, is the highest safest voltages that can be applied to that particular type of insulation material. So if you hear an electrician say a wire is good for 110 or 220 volts, what is meant is that the same wire can be used for either 110 or 220 volts. To answer the question, you don't need to change a 220 volt wire to a 110 volt wire because it is good for both voltages.

How is 220v water heater rewired to 110v?
Use a transformer to lower from 220 to 110V.
Plug a 110v hair straightener into a 220v outlet?
Do not do this.
Can you use the 220v 50hz appliances in 110v 60hz?
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
What causes a 220v wire to pull only 110v?
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.
Where can one buy a 110V transformer online?
The online retailer Amazon currently has an 'Automatic Transformer Adapter 500W 110v/220v 220v/110v' on sale for $38.89. That's 51% lower than the list price of $79.99 and that's before the free shipping!

Can you attach an iron machine of 220v in a 110v socket?
No
Plug a 110v hair straightener into a 220v outlet?
Do not do this.
Can you plug your 220V electric piano into a 110V socket?
No.
Why 220v and 110v was chosen as standard voltage in Brazil and not some other voltage?
220v and 110v are almost the only voltages used around the world because they are the most efficient.
Can you use the 220v 50hz appliances in 110v 60hz?
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.

Does avr converts 220v to 110v?
yes, but you need a transformer to convert it,
Can a 2-pole circuit breaker be used for 110V 220V or 440V?
All three, on 110V a split receptacle, on 220V a baseboard heater, on 440V a construction heater or similar resistive load.
If you have a computer which start with 110v so by using converter can the computer starts with 220v?
Yes. If the computer power input is only rated for 110V input, you can power it from 220V by using a voltage converter from 220V to 110V with appropriate wattage. Some computer power supplies also have a switch for setting 110V/220V in which case computer can be powered from 220V after changing the setting. Most of the portable computers/laptops have power adapters which are rated for universal voltage (e.g. my Dell laptop AC adapter is rated for 100-240V 50-60Hz).

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.
