Add custom appliances to calculate total load and determine recommended MCB size automatically.
| Appliance Name | Quantity | Wattage per Appliance (W) | Action |
|---|---|---|---|
Electrical Load is the total power consumed by all electrical appliances in a space. Proper load calculation ensures safety, correct breaker sizing, and prevents overloading.
Current (I) = Load (W) ÷ Voltage (V) [Single Phase]
Current (I) = Load ÷ (Voltage × √3 × Power Factor 0.8) [Three Phase]
Recommended MCB is selected slightly higher than the calculated current using standard ratings: 6A, 10A, 16A, 20A, 25A, 32A, etc.
Total Load 6995W at 230V Single Phase → Current ≈ 30.41 A → Recommended MCB 32A
Yes, this dynamic calculator allows adding any number of appliances with custom wattage.
Yes, three-phase systems divide load and include √3 factor in calculation.
To protect wires, prevent overload, and ensure safe electrical design.
