Depends if it is the supply cable you are wiring or a cable to the outgoing side. If it is the supply cable you are connecting, call your electricity supply company. They are the only ones authorised to do that work. <><><> Three phase will be at 415V. So proceed with caution! If you want to install a new branch circuit cable you need to be sure you have a three phase supply with a triple pole breaker. If you don't know what you are doing then don't try it as you can easily damage the equipment or yourself! Call a licensed electrician to advise you and quote for doing the job safely and correctly. <><><>
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.

Yes, the minimum is three wires, usually used when the three phases are in balance, with equal currents in all three lines. In conditions when the three phases might be unbalanced, a neutral wire is added, which makes it a 3-phase 4-wire system, and the current in the neutral depends on how out-of-balance the currents in the three lines are.
The three windings are made the same to maintain a balance in the motor.
single phase, double phase & three phase
A three phase transformer is simply three transformers so, supplying one phase to a set of three transformers will result in only one phase output. Any loads connected to that transformer that are expecting three phase power will malfunction, and could fail.AnswerA three-phase transformer is NOT 'three separate single-phase transformers', as suggested in the original answer. It is a single transformer with three primary and secondary phase-windings wound around a common three-limb ('core') or five-limb ('shell') core. If a single-phase supply was applied to one of the three primary windings, then single phase voltages would appear across each of the three secondary windings and the remaining two primary windings. These voltages would not be out of phase with each other.
Yes, but you must have your neutral wire to form a return path for your current.
you have to ceck all your wire that is mains
if you don't know, call an electrician to do it for you?
three phase would be cheaper for running motors are more efficient single phase is only used for small motors and loads where operating economy is not a concern
if you will experience then you will know

A distribution board which has 7 segments , one for Main incomer, three as sub incomer for each phase and three for singlephase outgoing is called a 7 segment DB
On a Delta 3-phase you connect the single phase loads between pairs of the 3-phases. Warning both sides of these loads will be hot! You may want to use 3 isolation transformers so that the real loads have a neutral line.On Y 3-phase you connect the single phase loads between one of the 3-phases and neutral.In each case to balance the loads, try to put similar loads on each phase (or pair of phases).
no, don't need it.
