Installation, Start-Up and Owner’s Manual
Essential Circuits
Consult with owner to clearly identify the circuits in
building that are "essential".
It is important that you understand which circuits the
owner wants to include as "Essential Circuits". Depending
on the power consumed by these circuits, most or all of
them can be switched to the Home Standby Generator for
the duration of normal power interruption.
The wattage reference guide shown in Figure 2 will assist
the owner with their decision-making process. It provides
the wattage used by many ordinary household devices. Use
it as a guide when selecting essential circuits. Review this
information with the owner and convey any technical
considerations that might affect the cost of installation.
Essential Circuit Selection
When selecting the essential circuits that will be switched to
“Standby 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 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
Standby Generator:
• 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 Standby Generator
complies with the following “stationary standby
power rating”:
The standby power rating is applicable for supplying
power for the duration of normal power interruption.
NO sustained overload capability is available for this
rating.
