To determine the generator size needed to supply the electrical demand in your home, refer to the table below:
Remember 1 kw = 1000 watts, 2 kw = 2000 watts etc. The formula for finding wattage is: volts x amps = watts.
Example: an appliance nameplate states 3 amps at 120 volts. 3 amps x 120 volts = 360 watts.
