It is critical to understand the starting methods used for 3-phase motor loads. Each has unique requirements and affect what size generator is required to start the motor. Unlike the utility grid, generators are limited in their motor starting capacity based on the capability of their alternator. WebHowever, here is an example of calculating generator sizing yourself. For example, assume you want a generator that will power a small refrigerator. You consult the refrigerator owner’s manual and find that the running wattage for the device is 350 watts. Running Wattage (R) = 350 watts. Starting Wattage (S) = 350 x 3 = 1,050 watts. cinnamon remedies weight loss
