Essential Circuit Selection
When selecting the essential circuits that will be switched to “Backup Power,” it is important that the sum of the combined circuit loads does not exceed the wattage/amperage capacity of the generator.To help you with your selection of essential circuits, please consider the following:
Add up the total wattage of all electrical devices to be connected at one time.This total should NOT be greater than the generator’s wattage capacity.
The rated wattage of lights can be taken from light bulbs. The rated wattage of tools, appliances and motors can usually be found on a data plate or decal affixed to the device.
If the appliance, tool or motor does not give wattage, multiply 120 Volts times the ampere rating to determine watts (Volts x Amps = Watts).
Some electric motors (induction types) require about three times more watts of power for starting than for running.This surge lasts for only a few seconds. Be sure you allow for this high starting wattage when selecting electrical devices that will be energized by the Home Generator System:
•Figure the watts required to start the largest motor.
•Add that to the total running watts of all other connected loads.
This Briggs & Stratton Home Generator System complies with the following “stationary standby power rating”:
The standby power rating is applicable for supplying emergency power for the duration of normal power interruption. No sustained overload capability is available for this rating.
This rating is applicable to installations served by a reliable normal utility source.This rating is only applicable to variable loads with an average load factor of 80% of the standby rating for a maximum of 500 hours of operation per year.The standby rating is only applicable for emergency and standby power where the generator set serves as the backup to the normal utility source.
Use the “Wattage Reference Guide” provided and mark those circuits you consider “critical” or “essential”. Make sure you and your installer consider the system’s altitude above sea level and the ambient temperature range when determining total generator load.
