How big a generator do I need to run a refrigerator?

For example, if you want a generator to run a refrigerator and freezer, the power (Table 2) of the refrigerator would be 800 and the freezer would be 1000. To select the correct size generator, decide whether the refrigerator and freezer should start at the same time. In this case, you would need 1 800 X 4) 7 200 watts.
