Three phase allows power to be transmitted efficiently using three live wires. The voltages in the wires reach the peak of the AC cycle in turn, which allows each wire to act as the return wire for the other two, provided the currents in the wires are equal.
In some cases the load currents in the three live wires are unequal, so the system is described as unbalanced, and in this case a 4th wire is added as a neutral. If the system happens to be balanced, the current in the neutral is zero.
The 4-wire system allows single-phase loads to be connected between one live wire and neutral, and this type of supply is widely used throughout Europe to provide power to groups of houses. Over a sufficiently large number of houses the currents in the three phases are reasonably equal.

How do you connect neutral wire in a threephase distribution board?
In a three-phase distribution board, the neutral wire is typically connected to a neutral bus bar, which serves as a common point for all neutral conductors from the three-phase circuits. The neutral bus bar is then bonded to the ground to ensure safety and prevent potential electrical hazards. It is essential to ensure that the neutral connections are secure and that the system is balanced to avoid overloading the neutral wire. Additionally, local electrical codes and regulations should always be followed when making these connections.
