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.

How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
What is the difference between an open delta and an open wye connection?
An open delta connection is a delta connection with one phase removed, but still supplied with three line conductors. An open wye is a wye connection with one phase removed, supplying a three line conductors and a neutral conductor. An open-delta/open-wye is a method of providing a reduced-load three-phase supply using just two single-phase transformers, rather than the preferred method of using three single-phase transformers.
How many wire or core in three phase electrical connection and single-phase electrical connection?
A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
Why cant take connection from phase line to neutral line?
A connection can be taken between phase lines, or between one phase and neutral. Both methods give a single-phase supply. Between phases the voltage is sqrt(3) times more than between one phase and neutral. In each case the load gives an unbalanced current on the 3-phase system but the idea is to average out the unbalances over a group of single-phase loads.
What are the procedures for the connection of single and multi-phase circuits?
Check continuity
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
What type of connection do you use in household connections?
its simple: its either single phase or three phase connection
What happens when a phase gets short and also when it get opened in a delta and star connection?
In star connection when two phase is short,it work as single phase system. In delta when one phase is open ,it work as a single phase.
What does one mean by 3-phase loads?
Electrical circuits are designed in two phase types. Either single phase or three phase. A single phase is one wave of electricity while three phase is three waves that are offset.
What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
Can you use 3 phase circuit as 3 separate single phase circuit?
yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits
How can you get 3 phase connection?
If you have single phase now, you have two options. One, is to install a three phase service or Two, install a roto phase device.
Can a 2 pole breaker to protect 1 phase circuits and 2 phase circuits?
Probably
Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
If you are making your own device and you bring in 208 3 phase for part of your needs - how can you properly tap 110 single phase from it to operate other parts of your device?
Your incoming 208V 3 phase power supply will also need an incoming neutral of the same conductor size. Then any single pole breaker installed in the panel will have 110 volts to the neutral. That is you can run 208V 3 phase motor circuits from a three phase breakers in the panel and any number of 110V circuits from single pole breakers.
