In my home I have 3 phase supply. Regular ELCB is installed on each single phase.
But I had a problem of power surge inside my home possibly due to neutral connection in the distribution transformer. During short period, possibly single phase load experiences full phase to phase voltage.
During this time, my single phase ELCB trips but before that there is a equipment damage also.

For neutral cuts/loose contacts of three phase supply in 4 pole RCCB is the solution to protect the equipments in my home?
