Load Breakdown
► Formulas & Method
Load Schedule Method
Row W = Qty × Watt/unit × Demand Factor
Total W = Σ(all row watts)
Adjusted W = Total W × Diversity Factor
1Φ Current = Adjusted W / (V × cosφ) × Safety Factor
3Φ Current = Adjusted W / (√3 × V × cosφ) × Safety Factor
Breaker = next standard size ≥ Design I
Cable = min. Cu size per IEC 60364 for breaker rating
Daily Wh = Σ(Qty × W × Hours)
Monthly Cost = Daily kWh × 30 × Rate (৳/kWh)
⚠ Disclaimer: This calculator provides estimates based on standard electrical engineering practices (IEC 60364). Cable sizes are simplified recommendations — actual sizing must consider installation method, ambient temperature, grouping, and voltage drop. Consult a licensed electrical engineer for final designs.
