The 220-240 VAC breaker must span both bus bars in the panel. Therefore it is either double the height (top to bottom - usual circumstance) or double the width (side to side in some older boxes).

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.
Is there anyway to get 220V 60hz from a 110V 50hz power supply?
It would involve some electronics work but it could be done. Might add that it could be more expensive than just buying the proper power supply. Use Use 220V 60hz motor to run 110V 50hz Generator.
Can you replace a 110V hospital bed motor with 220V motor?
Yes, if you rewire the bed and rewire the plug on the wall to 220 volts.
Did you burn up your motor if you plugged in 220V to a 110V?
Yes, although you might have lucked out and tripped the breaker first.
How is 220v water heater rewired to 110v?
Use a transformer to lower from 220 to 110V.
What is best to use 230volt or 110volt water pumps?
Either. Motor size or your available power local to the pump installation are the determining factors. If you have to use a large motor, 220v requires less amp draw on the circuit and allows a smaller wire than a large motor running 110v. If 110v is already there and you only need a small motor, run 110v.
Which is better 220 versus 110 volts both with 20 amps?
At 20 amps the 220V will supply twice (2x) the power that the 110V will supply. The answer depends upon your meaning of the term 'better'. If you have a specific size load that you are supplying such as a motor that will accept either 220V or 110V then by using 220V you will have less of an impact from voltage drop and the conductor size will be smaller due to the current being 1/2 of the 110V. If by better you mean which one will give you the most power then the obvious answer is 220V.
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.
Can you run a 60hz 110V motor on 50 hz 220V with a step down transformer?
NO dear we can not rotate a 110 vlolt motor on 220,but if your voltage is 110v then y can rotate it on 50hz ,no problem,but it will rotate at lower speed, ENGR. NASEER AHMED,PAKISTAN
How can one tell weather a motor is wired for 110 or 220 volts without looking at any label's?
You should always check the labels, but in most cases the power cord connectors are different between the 110v and 220v.
What happens when both 110v leads are applied to one side of a 220v electric motor?
The breaker will blow because you are effectively causing a short circuit.
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.
