Briggs & Stratton Power Products Backup Power System
Essential Circuit Selection
When selecting the essential circuits that will be switched
Running
to "Backup Power," it is important that the sum of the
Watts
combined circuit loads does not exceed the
1700
wattage/amperage capacity of the generator.To help you
3800
with your selection of essential circuits, please consider the
6000
following:
500
800 to 1000
Add up the total wattage of all electrical devices to be
5750
connected at one time.This total should NOT be
700
greater than the generator's wattage capacity.
1150
The rated wattage of lights can be taken from light bulbs.
1750
The rated wattage of tools, appliances and motors can
2000
usually be found on a data plate or decal affixed to the
1400
device.
1800
If the appliance, tool or motor does not give wattage,
700
multiply 120 Volts times the ampere rating to determine
650
watts (Volts x Amps = Watts).
400
Some electric motors (induction types) require about
1500
three times more watts of power for starting than for
1250
running.This surge lasts for only a few seconds. Be sure
700
you allow for this high starting wattage when selecting
875
electrical devices that will be energized by the backup
500 to 750
power system:
1200
250 to 1100
Figure the watts required to start the largest motor.
1200
Add that to the total running watts of all other
800
connected loads.
100
This Briggs & Stratton Backup Power System
700 to 1000
complies with the following "stationary standby
1100
power rating":
300
The standby power rating is applicable for supplying
400
emergency power for the duration of normal power
150
225
interruption. No sustained overload capability is available
for this rating.
50 to 200
700
This rating is applicable to installations served by a
200
reliable normal utility source.This rating is only applicable
2000
to variable loads with an average load factor of 80% of
1500
the standby rating for a maximum of 500 hours of
2800
operation per year.The standby rating is only applicable
800 to 1050
for emergency and standby power where the generator
1750 to 2000
set serves as the backup to the normal utility source.
200 to 500
Use the "Wattage Reference Guide" provided and mark
1000 to 1650
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.
