Rated, or running wattage, is the amount of electricity necessary to run your appliances continually. Surge, or starting wattage, is the additional amount of electricity needed for 2-3 seconds to start electric motors commonly found in household appliances (such as a furnace fan or refrigerator).
What is the difference between surge watts and running watts on a generator?
A circuit breaker rated close to the continuous power capacity—running watts—prevents overloads but still allows higher levels of current—surge watts—to flow for a very short period. This allows the generator to start motors within the limits of the generator.
What is a good wattage for a generator?
With a generator rated at 5,000 to 7,500 watts, you can run even the most critical household equipment, including things such as refrigerator, freezer, well pump, and lighting circuits. A 7500-running watt generator can run all these appliances at once. For RV, a 3000-4000-watt generator will work great.
What is generator surge capacity?
Surge Watts or Start up Power of an Electrical Appliance They require additional watts to start them. This additional watt may also be referred to as the surge watt of the device. The surge watts required by these devices may sometimes be two or three times the watts required to run the device.
How many surge watts does a refrigerator use?
In reading this table, take a standard refrigerator/freezer for example. To continuously run the unit, you need approximately 800 watts. However when the compressor kicks in, it requires a the additional 1200 surge watts. So it takes 2000 watts to supply ongoing power to your refrigerator/freezer.
Why do generators have starting watts and running watts?
Running , or rated watts are the continuous watts needed to keep items running. Starting watts are extra watts needed for two to three seconds to start motor-driven products like a refrigerator or circular saw, this is the maximum wattage the generator can produce.
What size generator do I need for a 200 amp service?
If you have a 200 Amp service panel, use a 15-20 kW GenSet if you have an air conditioning or large well pump. If you have a 400 Amp service panel, use a 30-50 kW GenSet, if you have lots of air conditioning or other larger loads, use the large size in the range.

How do I know what wattage my surge is?
If the rated/running watts are not on the tool or appliance, you may estimate using the following equation: WATTS=VOLTS x AMPS. Only motor-driven items will have an additional surge requirement. The additional surge watts required may be estimated at 1 – 2x the rated/running watts.
What will 2200 watts run?
Room Air Conditioner, small. Power Tools i.e. Drill, Grinder, Sawzall. Kitchen Appliances i.e. Microwave or Electric Frying Pan. Fans & Lights.
How do I calculate generator wattage?
The wattage is calculated by multiplying the voltage by the electrical device’s load capacity in amperage (Watts = Volts x Amps). For example, a generator may be listed as 1,500 watts delivering 120 volts.
WHAT CAN 3.5 KVA generator carry?
