How many kilowatts does it take to run 200 amp home?

Answer 1

The maximum would be 200 x 240 = 48 kilowatts assuming you had normal 3 wire service. However, your home would never use that much. Average would probably be about 3 or 4 kilowatts, depending on time of day and your heating and air-conditioning systems.

Your electric utility bill probably tells you how many kilowatt-hours you used in a month. Just divide this by 730 which is the number of hours in the average month, and that will give your average load in kilowatts for that month.

Answer 2

To calculate the kilowatts needed to run a 200-amp home, you would need to know the voltage of the electrical system. Assuming it's a standard 240-volt system, you would calculate it as follows: 200 amps * 240 volts = 48,000 watts or 48 kilowatts.
