A 220v heater has two 110v lines coming into it--either two 110v lines with a neutral, like a range, or two 110v lines with no neutral, like a water heater. Unless there's a fan in the system, they only use two wires. It's cheaper that way. If you have a DEDICATED circuit for each 220v heater--one where there's only one thing on the breaker--and you have at least 10/2 wire (unless the amps call for 8/2 or 6/2 wiring, which happens), you can install a two-pole breaker to feed 220v to the heater. If you're just trying to plug the heater into an outlet and get it to work, you've got a problem in that you can't pull 220v out of a 110v outlet no matter how hard you try. Sorry.

How is the power supply in Europe delivered with two wires and still 220 volts?
Oh yes. They do provide 2-wire 220V and even 2-Wire 240V service in Europe. We went a different way in the States early on when we attached a center-tap wire in those same service transformers to provide 2 x 110V services, along with one 220V service. It is worthy to mention that 110V (220V) services in the US progressed to 115 (230V) and now stand at 120V (240V).
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.
Electric range 220 or 110?
Electrical range is usually 220V and requires at least a 40A breaker. In a three wire configuration, the white power carries 110V, the black wire carries 220V and the green wire is the ground. A four wire configuration has an additional wire that is neutral.
How can you supply 220v machine to 208v supply?
Most 220 volt equipment will work on 208 volt supply. If the machine has a resistive load then the watts output will be lower than if supplied from a 220 volt source. If it is a motor load you will find that the equipment may run a bit slower but most motors will take the lower voltage. If the machine is a plug in device, install the appropriate receptacle to match the pin configuration and plug it in. If it is a hard wire installation this should be done by a qualified person.
A water heater draws 40A from a 120V power source in 10m away What is the minimum cross section of the wire that can be used if the voltage applied to the heater is not lower than 115V?
You could do it with 8-gauge wire, assuming you could even get a 110v water heater like that--4000-watt water heaters are all 220v.
What gauge wire is needed to supply a 220v 50' 30amp service?
10 AWG.
How do I get 220 volt circuit?
If you need a 220v circuit at only 15 or 20 amps: Get a new breaker to replace your 110v single pole breaker with a 220v double pole breaker. (You cannot exceed the original breaker's amperage rating unless you also replace the wire with a larger size). Shut off the panel's main breaker (the wires coming into the main breaker will remain hot, so don't touch them.) Remove the old 110v circuit's neutral (white) from the neutral bus bar in your distribution panel. Remove the old 110v circuit's hot (black) from the old 110v breaker. Remove the old 110v breaker. Install the new 220v breaker in place of the old breaker. (This may require you to rearrange some breakers if the old breaker was in between others) Reconnect the black wire to one terminal of the 220v breaker, and reconnect the white wire to the other terminal. Turn on the main breaker, and your new 220v breaker. Before you do this, be sure where the actual circuit goes. Changing 110v to 220v if the circuit is feeding regular 110v receptacles will cause damage to devices plugged into them. Be sure you remove all 110v devices (receptacles) from the circuit before converting it. If you need a 220v circuit for a dryer or other large appliance, your existing wiring will not be sufficient to do the above. You will need to install a new breaker and wiring. For this task, you should consult a professional electrician.
How do you wire 240V straight blade outlet when both screws are brass?
Both screws are brass because in the US you need two hots to get 220V. In a 220V only circuit you do not connect the neutral, only two hots and a ground. This is why 220V breakers are twice as wide as 110V and have two terminals instead of one.
How do you run a clothes dryer line to a fuse box that has glass fuses if there are 2 in the box that are not being used?
You need a 220V cartridge fuse block open, not just two 110V fuses. Fusing a 220V device with two 110V fuses at the panel is dangerous and doesn't meet code. If you have a 220V fuse block open, simply wire the two hots to the block, and then wire the neutral and ground normally. If you have fuses make sure the box and the feed can handle a clothes dryer. It may be wise to have an electrician evaluate the system for safety.
Can I use a 220V oven with 110V outlet?
No, and if you don't have a 220v outlet, you will need an electrician to run a #8 copper wire with a direct line to the electrical panel (40 or 50 amp), depending on the oven's requirments - check the manual.
How many volts does a wire feed welder need?
that depends on the size of the welder. some welders can be used with a 110V outlet and others need a 220V. the size of the welder is the decider on that. Tech Ed Ted
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.
