Nameplate watts
Connected load calculator
The sample watts are only a starting sheet. Change each one to the input power printed on the appliance. A tonnage is not a wattage, and the total is not a sanctioned load.
Connected load
3.72 kW
3,720 W. About 16.2 A at 230 V single phase, or 5.2 A if the same watts were spread across 415 V three phase. Power factor is taken as 1 until you know the nameplate figure.
These figures are for planning. Cable size, the breaker and the final list have to be confirmed against the drawing, the load and the Havells datasheet.

Reading the total
Is this the sanctioned load?
No. It is the sum of the watts you type. A new connection uses the electricity board’s own form and diversity, which this page does not apply.
Can I enter an air-conditioner in tons?
No. Use the input watts printed on the indoor unit. Tonnage is not a wattage.
