Electrical Load Calculation for Nepali Homes: Simple Guide
How SDR calculates your home load for NEA sanction — add AC, geyser and EV before applying for 15A to 60A.
Add your load in 5 minutes
List every watt: 1 AC 1.5T = 1500W, geyser 2000W, EV 7000W, lights 500W. Divide by 230V. SDR uses 0.8 diversity — e.g., 12kW installed = 9.6kW sanction, so apply 45A three-phase, not 25A single.
- Apply formula: Amps = (Total Watts × 0.8)/230
- Add 20% future buffer
- EV always dedicated 32A
