@Afghan_Engineer Accurate 3-phase load calculation → ~635 A; with 20% margin ≈ 762 A, so selecting an 800 A breaker is correct and practical ✔️

Breaker Size Calculation Breaker size calculation is a critical step in electrical system design to ensure safe and reliable operation of equipment. As shown in the reference, the total load is first determined by summing all connected loads such as motors (250 kW), lighting (40 kW), heating (30 kW), and other loads (45 kW), giving a total of 365 kW. This is converted to watts and used in the three-phase power formula: P = \sqrt{3} \times V \times I \times PF Rearranging the formula allows calculation of current based on system voltage (415 V) and power factor (0.8), resulting in approximately 634.75 A. To ensure reliability and account for uncertainties, a safety margin of 20% is added, increasing the current to about 761.65 A. Since breakers come in standard ratings, the next higher available size is selected, which is 800 A. This ensures the breaker can handle peak loads without nuisance tripping while still providing protection against overloads and faults.
