Hire an electrician. Meter feeds are usually unfused. Any mistakes will cause a nasty fire, and draw the ire of the power company, the fire department, and your local house inspectors. You do not want to make a mistake on a 220V unfused line.
A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
On a step down transformer XO symbol denotes the secondary split phase grounding point. This is also where the neutral of the three wire secondary is connected. The transformer connection is known as a single phase - three wire - with one secondary winding.
This depends on the voltage, and whether it is a three phase or single phase transformer.
By design are you going to wind the transformer yourself? In your design you need a 5:1 ratio. On the output side of the transformer any two legs of a three phase transformer is considered single phase voltage. Good luck on your project.
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.

A transformer that is for a single phase, or wire set (hot and return). Any small electronic device that you plug into a wall socket likely uses a single phase transformer to step the outlet voltage down to 5-24 volts.a transfer is a static piece of equment used ither for rising or lowering the voltege of an a.c soply with correspond incrise or decrise current .
By having a transformer with 3 phase input and single phase out put
Harmonics are really not needed in single phase transformers.
Your question is rather vague. If you are asking what do you call a group of single-phase transformers, connected to supply three phase, then the answer is a 'three-phase transformer bank'.
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.

Yes, you can use three single phase transformers on three phase applications and interconnect them to serve as a single transformer or you could use one single phase transformer fed from two of the three lines in a step down application.
