Your Generator Needs

To determine whether a generator is appropriate for your needs, you need to first add up the wattage of tools, appliances, and motors you want to run at the same time. Then select a generator with the running wattage rating to match or exceed the total load.

Keep in mind that tools and appliances with electric motors require additional surge wattage at startup that can be double or triple the normal running wattage requirement. Look at the surge watts required and make sure you choose a generator with enough additional wattage to start them. (And remember that you're typically not starting more than half of the items at the same time.)

Here's a sampling of power ratings for common household appliances.
