β‘ 100A Three-Pole MCCB: The Right Breaker for Your House? π
In a three-phase residential electrical installation, the main MCCB and individual circuit breakers perform different roles.
πΉ Main MCCB: Provides main overcurrent protection when correctly selected for the installation.
πΉ Individual MCBs: Protect separate circuits for ACs, refrigerators, kitchen appliances, geysers, and lighting.
πΉ Cable Selection: Cable size and breaker ratings must be coordinated.
πΉ MEP Drawings: Always follow the approved electrical design rather than selecting breakers by guesswork.
π In DHA and Bahria projects, the correct combination of cable sizing, load calculation, and circuit protection is essential for a safe installation.
β οΈ Remember: A 100A MCCB is not automatically suitable for every house. Final selection depends on the calculated load, cable capacity, and electrical design.
