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

How do you rewire a 220 volt receptacle to produce 110 volts?

A 220 volt receptacle is a receptacle which has 2 wires carrying 110 volts...it has two "hot" wires at 110 and a neutral or common leg which has no voltage. A 110 volt receptacle is a receptacle which has 1 wire which carries 110 volts and a common wire. The wiring in the USA is almost standardized now to where the two "hot" (carrying 110 volts) wires are colored black and red, and the common or neutral is white. To change a receptacle to 110 volts..you remove the red or black wire from the old receptacle and wire nut it off...leaving the other red or black to attach to the new receptacle (right side of receptacle usually, looking at it from the grounding hole on the receptacle ON THE BOTTOM). You then connect the white wire to the left side of the receptacle. This will provide only 110 volts now. If the wires are not black, red, and white..they may be black, black, and white. In most cases, the white wire is always the neutral or common wire. When in doubt, buy a voltmeter and check each wire to the metal box in the wall...the wires carrying the 110 volts will usually read 110 on the voltmeter (or 115, 118..etc). Good luck!


What circuit breaker to install for 10 amp 250 volt circuit?

For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.


How do you use volts?

Volts are used to measure the electrical potential difference or voltage in a circuit. To use volts, you would typically measure the voltage across a component in a circuit using a multimeter or voltmeter. This helps in determining if the component is receiving the correct amount of voltage for proper operation.


How do you change 110 volts to 240 volts?

You need to change the circuit breaker and sometimes the wiring itself. For example, if you have a 120 volt circuit with a black wire as the hot and the white as a neutral you would take the white wire off the neutral bar of the circuit breaker panel and put it on one leg of a 240 volt breaker. The receptacle would have to be changed as well. The white wire should be re colored to black or red.


Do you have a circuit breaker which operates for one millon volts?

Circuit breakers are typically designed for lower voltages, such as up to 1000 volts. For extremely high voltages like one million volts, special high-voltage circuit breakers or other protection devices would be used in power systems. These specialized devices are designed to handle the unique challenges posed by very high voltage levels.

How much Ampere when volt 415?

That would depend on the power output (watts) of the circuit. Volts times the Amperage equals the Wattage of the circuit. You do not have enough information in your question. Volts is the force applied to move the electrons in the circuit, and amps are a measure of the quantity of electrons moved through the circuit over time. Thus a circuit of 415 volts and 1 ampere will deliver 415 watt-hours of power. Yet a circuit of 1 volt at 415 amps will deliver the same 415 watt-hours of power, but with less force.

120 volts equal how many watts?

It depends upon how much amperage is utilized in a circuit. A circuit with 2 amps of current and 120 volts would consume 240 watts of power. The same circuit with 4 amps would produce 480 watts. You have to have 2 values of Ohm's law to figure out the third. See "Ohm's law" on the internet for more information on how circuit values are determined.
