Hi experts. i am a non professional unqualified hobbiest electrian only lean and work in do it yourself manner. my question is if Electic supply company disconnects both neutral and phase supplies to accomplish power cuts ?

A power cut that is caused by a fault could be any combination of phases and or neutral.

In a single phase installation, a loss of either phase or neutral in the cable directly supplying you and only you will cause a loss of power.

A loss of neutral further up the line, before it is split to several houses can cause the voltage in your house to “float” between 0 and 400v

If a fault only affects 1 of the 4 cables, ( L1, L2, L3, N) more often than not, the subsequent repair work will disconnect all of them to allow a safe working environment for the repair crew.

as above^^^^> a power cut is caused by a fault. a power outage is a fault or a deliberate disconnection, usually for maintenance
