I have 3 phase 220V domestic power supply to my home by 16 mm aluminium 4 core armored cable. I have a sanction of 15KW load. With a concern for safety I intend to retrofit a MCCB of suitable rating. Request you to please guide me with respect to Amperage, Icu 240V, Icu 410V & Ics 415 V ratings required for the MCCB.
Let me know if you require any additional information.
