Suggest best connectivity at 415V swgr in the diagram

(OP)


100kW Solar PV system Connectivity is proposed as shown in the diagram. Grid Connectivity to a module with 200 Amps fuses at 415 v Swgr (at 'B') is proposed. 415 V MCC is highly important swgr located in a power plant. The question is what can be the best way of connectivity at 'B' so that any kind of faults from 'A' to 'B' will not cause supply interruption or tripping of MCC. Whether another MCCB or ELCB can be introduced at 'B'.
