The voltage in North America can be as low as 110 and as high as 125 volts. The average is about 115 to 117 volts. <><><>><> House voltage in the US is generally 120v line to neutral and 240v line to line. It is referred to as a "120/240v single phase service." Actual voltage can be as low as 110/220 or as high as 125/250.
If the meter has 208-240V coming to it, no the neutral doesn't go through the meter. If the meter has only 120V incoming power such as many RV parks then the neutral does go to the line side of the meter or it won't work.
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D
Hire an electrician to install for you a 240 line. I agree with Tim. You need a dedicated circuit for a dryer. The wiring is larger and you cannot use the 12/2 wiring that is already there. You need a home run from the dryer to the electricl panel. You need an electrican.
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.

I would caution you that it might be dangerous to do that. The voltages of the electricity supplied to houses in some European countries differ from the one on this continent. For anything short-term, they sell converters that can protect your equipment when plugging into a non-standard outlet, which would be much safer. However, to answer your question, in a European house you would need the final line transformer providing 230V from the power company to have a center tapped neutral, which they do not currently have, and so you would have to have a custom transformer... who knows what that would take in terms of safety regulations or permits. (In the US 240V is the main voltage coming into the house, and they use a center tapped transformer secondary tied to house neutral on the house side. The voltages available inside the US house are 120V from each line to neutral and 240V from line to line.)
The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60HZ
If the meter has 208-240V coming to it, no the neutral doesn't go through the meter. If the meter has only 120V incoming power such as many RV parks then the neutral does go to the line side of the meter or it won't work.
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
you do NOT put two 110v breakers in. you put 1 two pole breaker in. the panel is designed to give you 220v off one side OR the other side if you use a 2 pole breaker on one side or the other side. If you look at both 120V lines on an oscilloscope you will notice that they are both 120V to the neutral, but they are 180 degrees out of phase. This means that when one hot is at +120V the other is at -120V. So between the two you have 240V. If you put your meter across both hots you should see 240V. If you do not see 240V across both hots you (or an unlicenced electrician) has wired the outlet without using a proper 220V breaker. You do not see 240V because the hots are in phase, to the voltage differential is 0V, not 240V. 220V breakers cannot do this, unless forcebly installed in the wrong type panel. More than likely someone tried to wire it with 110V breakers.

...It "supplies the power" to whatever device you're referring to.Baffling, I know.Another answer:A power supply converts 120V or 240V AC power (sometimes called "wall", "line" or "mains" power) into various regulated DC voltages needed in a piece of electronic equipment. In a computer, for example, the power supply will typically provide +12V, +5V, +3.3V and -12V sources to the various components. Voltage regulators in the power supply help keep the voltages steady, even when the input voltage sags.
