Surge or Starting Wattage refers to the additional power required to start an electric motor load. This wattage lasts for a short period, typically two to three seconds, before dropping down to the typical running wattage. Generators are also capable of providing surge wattage, which is the maximum wattage the generator can deliver for a brief period of time.
For example, a refrigerator/freezer typically requires 700 running watts but can surge to 2200 watts, while a clothes dryer (electric) requires 5400 running watts and can surge to 6750 watts. This information can be used to determine the appropriate generator size for powering these tools and appliances during a power outage. |
