Dear friend ,
First measure the current flowing thro MCCB .If it is MCCB
then it must have protective system . Set it as per max
current.measure the neutral current at full load. measure
neutal to earth voltage . most possible reasons are
1] Neutral link is undersized or
2] Loose connections
3] Neutral is not properly earthed .
