Does the start-up of an engine or motor require a different wattage?
As mentioned above, many engine startups take an extra large amount of amperage for their initial start-up. Some appliances and tools, such as the refrigerator or freezer, furnace fan, air conditioner, electric chain saw, weed trimmer, etc. will soak up more watts than normal when you initiate the startup. Therefore, don’t buy your home electrical generators without taking into account the surge requirement rather than just the normal running wattage.
