Sizing the Load

A crucial step in choosing a generator is ensuring that you get a model that will supply enough power for your application. We have provided an average wattage rating for most common electricity-using household appliances and devices, which will help you tally your needs. Keep in mind that when you've lost the power at your home, you probably will not run every appliance or device at the same time. 

Portable generators are intended to temporarily provide for your basic needs during an emergency situation and standby generators provide enough power for all your needs.

Note that the figures listed below do not include 20 percent more watts than the actual total and are typical household ratings found in many modern homes. The addition is required because it compensates for differing wattage ratings among appliances and devices; it also accounts for the fact that the circuit breakers on a generator tend to shut off power before maximum load is reached, a move designed to protect the wiring. Don't be surprised if the initial wattage total you get seems high. You might need to run the calculation two or even three times before you arrive at a figure that more accurately matches your essential requirements.
