The following chart may serve as a guideline for estimating generator capacity required on a residential installation. The chart illustrates power consumption of home appliances based on industry averages. These values should be verified against the product manual for the specific appliance(s) in question. It is also recommended that a certified electrician review this data for accuracy. You may print this form and fill in your actual values for calculation of kiloWatt (kW) requirements. Note: Appliances marked with "*" may consume up to 2.5 times the listed wattage during start-up.
