How much power does my home need during an emergency?
The wattage chart is intended to help you determine the essential
requirements of typical home appliances. Things like heating, air conditioning, your
security system, freezer, sump pump, microwave, or pre-determined lighting, etc. The
chart also allows you to determine or "stagger" special loads by alternating the
usage of specific appliances.
