two wires coming off the secondary of the transformer ex. residential voltage of 120 volts each line, and one neutral wire, L1 to neutral is 120 volts, L2 to neutral is 120 volts, L1 to L2 is 240 volts.
AnswerA single-phase, two-wire, system comprises a line conductor and a neutral conductor. In European countries, the line conductor for a residential supply is at a nominal potential of 230 V with respect to the neutral.
In North America, a 'split phase' system is used for residential supplies; this is a single-phase, three-wire, system comprising two line conductors which and a neutral conductor. The nominal potential difference between the line conductor is 240 V, while the potential of each line conductor with respect to the neutral is 120 V.

Can you tap off a 3 phase 277volt ac light fixture to power a single phase 120 volt ac recptacle?
NO! The voltages available in the 3-phase system are 480 (if you wire phase to phase) and 277 (if you wire phase to neutral) Don't try it!
What are the procedures for the connection of single and 3 phase circuits?
Single phase connection has 1 phase wire and a neutral wire. Another wire for protective earth. In three phase system, motor can be connected in star or delta. Most AC induction motors are in Delta. Power distribution system is generally 3 phase 4 wire. Transmission system is 3 phase high voltage. Industry uses 3 phase system, where as 1 phase is for domestic, commercial applications. Both 1 and 3 phase system has a frequency. It is either 50 Hz or 60 Hz, depending upon the country or region.
What is single phase dc system?
Single-phase means you have a simple AC supply on two wires, usually a live and neutral, as supplied to the average house throughout the world. Single-phase also includes a split-phase system where you have for example a 240 v supply with a centre-tap neutral giving two separate 120 v supplies. The alternative is three-phase, which can be on three wires or it can include a 4th neutral wire. It is used for transmission of power in bulk because it uses wire efficiently over long distances.
How do you convert 3 phase to 220 v single phase?
Single phase 220 V AC(measured Across the line and Neutral) Three wire system having one Live(L),one Neutral(N),one ground's. Two wire system having one Live(L),one Neutral(N). Two phase 220 V AC (measured Across the two phases i.e across Phase RY or across Phase YB or across Phase BR) . Three wire system having tow live (L), one Ground (G). Two wire system having two Live(L). Ramesh P
What is the difference between a single phase compressor and a 3 phase compressor?
One uses single phase AC current (120/240), the other uses 3 phase AC current (most households will not have 3 phase in their home) One uses a 3 phase motor the other a single phase motor. 3 phase is usually used in industrial applications while single phase is used in home or small business apps.

Explain the comparison between dc 2 wire system and ac single phase 2 wire system and ac 3 phase 3 wire system and ac 3 phase 4 wire system?
of all of dem 3 phase 3 wire is most economical as it uses less conductor dan in 4 wire system, 3 phase 3 wire is used in transmission and 4 wire in distribution as it has 3 live and one neutral wire. 3 phase needs lesser conductor size than 2 phase 4 wire for the same power. 3 wire dc feeder is more economical than 2 wire dc feeder for the same power. that was all i cud get..... hope u find it a lil helpful.

Why 3 phase ac systems is preferred to 4 phase?
3 phase system has more power than a single phase system

How has the three phase AC system changed society?
The three phase AC system has changed society due to it's direct effect on the economy and the reliability of the electrical source. Economy reasons due to less wire are being used comparing the single phase system. as well as less electrical poles for the transmission process of the electrical p from one area to another. Reliability reasons due to the higher efficiency and the lower line losses comparing to the single phase !
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
What are advantages of three phase ac and a single phase ac?
In a typical 3 phase system you have multiple voltages and configurations that can be used in either single phase or 3 phase, depending on how the circuit is designed. A single phase system is just single phase. You can have multiple voltages but it is always single phase.For example, in a typical 277/480v 3 phase system you can power 277v single phase lighting or equipment, 480v single phase lighting or equipment (which uses 2 legs of the 3 phase system but operates like any other single phase circuit), or 480v 3 phase motors.When comparing motors, a 3 phase motor will be substantially smaller than a single phase motor of the same horsepower. You can also reverse a 3 phase motor by switching any 2 leads. A single phase AC motor runs in one direction regardless of how the leads are connected.AnswerFor a given load, a three-phase transmission system requires less volume of copper in terms of conductor size, compared to single phase, so it is more economical to use three-phase.
Is Europe ac power single phase?
In Europe they have both single phase and three phase.
How do you reverse single phase ac motor to generator?

How do you convert 3 phase to 220 v single phase?
Single phase 220 V AC(measured Across the line and Neutral) Three wire system having one Live(L),one Neutral(N),one ground's. Two wire system having one Live(L),one Neutral(N). Two phase 220 V AC (measured Across the two phases i.e across Phase RY or across Phase YB or across Phase BR) . Three wire system having tow live (L), one Ground (G).
