COMMON APPLIANCE WATTAGES
AND SAMPLE SYSTEM CALCULATIONS |
|
Listed in the chart below are average running and starting wattages for a number of everyday appliances and equipment. From this table, select the most important items you want your generator to support. After you have made your initial selection, add the individual starting wattages to determine the base electrical load. The total is the APPROXIMATE size of generator required. A review by Romitti Electric can verify its accuracy. Once the final size is known, you may wish to add other non-critical items to the list to ensure uninterrupted service.
