It is done every day. The installation of a 200 amp house distribution panel is exactly that. Most home installations in North America are single phase, but there are a few three phase 120/208 starting to show up. The following is an explanation of the distribution system. To best explain this, visualize the three primary line that you see on pole tops in industrial areas. The voltage between these three lines is about 12,500 volts. When you see a pod of three Transformers mounted together they are combined into a three phase system. From each of the three high voltage lines, the voltage goes through three separate fuses and down to a high voltage bushing in each of the transformers. Inside the transformer the voltage goes through a coil and exits the transformer through a second high voltage bushing. This bushing is tied into the ground pad completing the circuit. This connection puts 7200 volts across the transformers primary coil. The secondary voltages of these transformers are determined by the customer that wants the three phase service. It could be 600, 480 or 240 volts. Each single transformer has two output bushings. These bushings can be wired into either a delta or star configuration depending on what the customer ordered. In a single phase service the name is derived from just using one of the three primary lines that are used above. It is the same primary connection, but the secondary is a bit different. The output secondary coil has three bushings coming out of the transformer. On the two outside bushings is the working voltage (for house connections 240 volts). The middle bushing is a center tap of the secondary coil. This gives a voltage of (bushing left to center 120 volts) and (bushing center to bushing right 120 volts) These are the three wires that come into a house for its 120/240 volt service. It is probably not a good idea to try to use a 220 amp circuit breaker on a single phase, if it is designed to operate as a two-phase main circuit breaker. Houses have two 120 VAC wires that are 180° out of phase with each other, giving you 240 VAC service. A two phase main breaker is designed to cut out both phases if either has an overload. It is probably intended to operate with a balanced current load (the same current in each phase). If you hook up only one half of the breaker, it may not work properly. Get a licensed electrician to work on your main power panel. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
To calculate the amperage, use the formula: Amps = Watts / Volts. For a 3000-watt load on a 220-volt AC single-phase circuit, the amperage would be approximately 13.6 amps.
A 220 single phase has two hot wires and a ground wire (green). You need one of the hot wires, a netural wire and a ground wire to make a 110 circuit. Now the 220 has a hot and a ground but no netural so you have to make a netural out of a separate wire. There are a lot more things to know and do, IE. safety first always disconnect the power and lock it out. 220 usually has a double pole breaker, do you have fuses or breakers. 110 needs a single pole breaker. Electricity is dangerous if you do not know, do not try, it will kill you, get an electrican or someone who knows to show you ONLY. TOUGH LOVE LARRY....
Having two wires on a single circuit breaker is not recommended as it can lead to overheating and potential fire hazards. Each circuit breaker should have only one wire connected to it to ensure proper protection and functioning of the electrical system. It is best to consult a licensed electrician to correct this issue.
is the measured voltage,generated between a line voltage and the starting point of a three phase transformer, which is the neutral point. Answer: it is an ac circuit in which the supply has a live and neutral wire, usually at one of the standard voltages 110/120v or 220/240 v. A three-phase circuit is a combination of three single-phase circuits with the phases of the voltages 120 degrees apart so that they peak in a regular sequence.

Nothing happens. This is a normal way to obtain a single phase system from a three phase system.
These are two completelydifferent systems and are incompatible with each other. Right from the manufacturer's specifications of the breakers down to the physical size of the electrical panels the breakers fit into.

They are in tandem because they power a 220 VAC circuit, rather then a 110 VAC circuit.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Use a transformer. A 208-240v single phase line has 2 power leads. Consult your local electrician for help! 440v systems are not for toying with when questions like this are asked.

The circuit feeding the 240volt items needs to be derived from two different "phases" or "hotlegs". If they come from the same "phase" you will not get 240volts, you will get zero volts. Further, if you are taking about a circuit breaker panel, at the point where you are taking the two phases, they are suppossed to be next to each other using a common trip 2 pole breaker.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
