Generally, we will distribute our 1 phase loads equally in 3
phases to get the balanced load and the circuit becomes star
connected. In star connection, there will be no current in
neutral line if the load is balanced.
In the lighting loads also we have to distribute equally in
3 phases. If not, current will increased in neutral.
In your case you did not devide the lighting load to get
balanced star connection, and also the neutral link in your
MCCB under size to carry unbalanced neutral current. And
also there may be loose connection at neutral link.
