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.

I have a situation to design sub-Distribution board/Panel meant for feeding power sockets. In the incomer CAN i Take TP MCCB with Neutral Link and All the outgoing feeders with to sockets with TP MCCB and Neutral Link? P.S : My System is IT Earthing
in cvt,there are two windings,1a,1n and 2a,2n.in my one project i use only one winding i.e.1a,1n. the other winding is not in use, so i connect it in open delta and want to close it by ibsertibg thermal resistor. the output of cvt is 132kv/115/sqrt3. plesae tell me exact value of resistor, so i may close it to avoid the resonance phenomenin. send me answer on this email adress please. aetcon-po@aetcon.com
