Essential Circuits
As a Home Generator System owner, it is important that
you clearly identify the circuits in your building that are
"essential" to you.Your Home Generator System is
equipped with a Semi-Automatic Transfer Switch.When
properly wired, your selection of essential circuits will be
transferred to the generator power within 10 seconds
(+/- 5 seconds) after the generator is connected and started.
It is important that your installer understand which circuits
you want to include as "Essential Circuits". Depending on
the power consumed by these circuits, most or all of them
can be switched to the Home Generator System for the
duration of normal power interruption.
The wattage reference guide shown in Figure 3 will assist
you with your decision-making process. It provides the
wattage used by many ordinary household devices. Use it as
a guide when selecting your essential circuits. Review this
information with your installer and ask about any technical
considerations that might affect the cost of your installation.
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.
