Wattage Per Household Appliance

Choosing the Right Generator

To choose the right generator, you need to accurately estimate your power requirements. Here’s a sample of wattages required by typical household appliances and tools. Start-up figures are momentary, they occur for a few seconds when a motor is switched on. (To find power ratings for your tools and appliances, check their manuals or read the information stamped on the device.)
