Yes, it is possible to lose 240V while still having 120V from the main power line to a house. This can occur if there is a fault or disconnection in one of the phases supplying the 240V circuit, which typically consists of two 120V lines. If one phase is lost, the 120V circuits connected to that phase will be affected, but the circuits on the other phase may still function normally. However, this situation can lead to unbalanced loads and potential issues with appliances.
What else can I help you with?
How can you plug 2000 watts 240v into a 120v 20 amp breaker with out replacing your breaker and all the plugs on the line?
You cannot safely plug a 2000 watt 240v appliance into a 120v 20 amp breaker without risking damage or fire hazard. To use the appliance, consider installing a step-up transformer to convert the voltage from 120v to 240v before plugging it in. This will ensure the appliance operates correctly without overloading the circuit.
What is the normal voltage of house electricity in the US?
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.
How can you convert a 240V clothes dryer to 120V?
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.
Is line voltage understood as any voltage?
Line voltage is understood as the voltage that the device or appliance needs to operate on. It is also referred to as the devices working voltage. Once the proper line voltage or working voltage is applied to the device it may be transformed to different voltages for different internal component circuits.
Single phase 4 pole Gen alt w 240V 60hz output no neutral. you check from each lead to ground and get 50-70V How do you get a neutral for connecting Gen to a standard breaker box having 240V and 120V?
Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.
Why are you not getting 240v between the two hot wires?
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.
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
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.

How do you replace a European plug with a North American plug?
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.)
How can you convert US 120V or 240V circuit into a single phase 240V circuit to use on a European appliance?
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
How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
If you have a 240V dryer and installed 30A breakers on both sides of the line reads 120 and 120 how do you get 240 and you have a receptacle that reads 30A 125250 and still does not work?
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.

What a power supply do?
...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.
