Electrical load calculation tells you how much power your home or shop needs and whether your wiring, breakers and UPS can handle it. This Electricity Load Calculator adds up the load of your appliances so you can size your electrical setup correctly.

The calculation totals the wattage of the appliances that run at the same time — the peak simultaneous load — which is the number that determines your main breaker, wire size and UPS capacity.

In Pakistani homes, the load grows with every appliance added: air conditioners alone can pull 1,500–2,500 W each. Knowing your total load prevents tripping breakers and guides decisions like upgrading the meter or choosing a UPS.

For solar sizing, the load calculation is equally essential: your system must cover the appliances you plan to run simultaneously, not the total of everything you own. This tool gives you that peak figure.
