Standard wiring for 220 volts which is also referred to as 240 volts, commonly has four wires. One is red, one is black, one is white and one is a bare copper wire. The red and black wire carry 120 volts each, the white wire in usually your neutral which hooks up to your ground along with the bare wire.

In a cental air unit which wires are black white and red?
the black wire is A phase, the red wire is B phase, and the white wire is the neutral. Black should have around 120 volts. Red should have 120 volts, and should add up to 240 volts with a multi meter.
How do you rewire 220 Volt lamp to 110 Volt?
You need a neutral wire. Household 220 is two 110V hot wires that are in opposite phases, so the voltages add. Each of these hots will provide 110V when used with a neutral. It may be routed with the two hots, and it may not. If there isn't one there, it will need to be run from your breaker box. If you have only one outlet or appliance to connect, you only need one of the two hots on one terminal of the outlet. The other side is where you need the white neutral.
What is an electric shared neutral?
An electric shared neutral is the white or negative wire that is shared between two electrical circuits on a basic single phase system. Most electrical devices use 120 volts and require a "hot" wire and a neutral wire to operate. Some larger devices use 240 volts and require two "hot" wires to operate. Two circuit breakers in an electrical panel can share one neutral wire as long as the breakers are not on the same "leg" of power. When looking at an electrical panel there are usually two "legs" of power feeding all the breakers, each leg has 120 Volts to ground, if the "legs" are combined you will have 240 Volts. A neutral wire can be shared by two circuits as long as the breakers are on separate "legs". If someone needed to add two circuits in their home, the could run what is called a 3-wire romex, It has a black wire, a red wire, a white wire and a ground wire. The white wire is the neutral for both the black and red 120 volt circuits, and the breakers for the new circuits would need to be on separate "legs" in the panel.
Can you add a 110 outlet from one leg of the 220 wiring?
Yes but I would not advise it. Get 110 volts somewhere else.
What is a 277 volt fluorescent fixture?
A 277 volt lighting fixture is one that is usually used in an industrial application. The reason for this is the voltage rating. A voltage potential of 277 volts is the voltage to neutral (ground) of a three phase four wire 480 volt distribution system. 480 volts / 1.73 = 277 volts. Rather than having to add a transformer to the system to provide 120 volts for lighting, manufactures produced a ballast for fluorescent fixtures that operates on the 227 volt potential.
What four consecutive prime numbers add up to 220?
The four consecutive prime numbers that add up to 220 are: 47+53+59+61 = 220
What is 220 add 25?
245
What is the difference between ordinary transformer an center tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
Can an American 240V dual phase dryer be converted to work in Korea with 240V single phase power?
you could possibly design a fix for it but it would be a lot of trouble. the American dryer has internal components that run off 110v and that 110v is available from the three wire 220v circuit in the typical usa residence. this is because of the third wire, the neutral. the Korean 220 would be 2 wire. you would have to go inside the dryer, add a 220/110 transformer and rewire the dryer so that the 110v loads come off that transformer. it would then no longer be ul listed and would have to be evaluated by the authority having jurisdiction in Korea and back here in the usa.
How do you add an extra 220v outlet to a 220v line?
Typically you need 4 conductors. The hot wires are usually red and black. The neutral is white and the ground is green. If you put a volt meter across red and black you'll get 220 VAC. If between neutral and either hot 110 VAC.
How do you add?
This is how you add! 100 + 120 ___ 220 well you add the ones placed first, then you add the tens, then hundreds, then thousands, and etc.
What would you add to a base to make it neutral?
You'd have to add an acid
