After the Guardian home standby system has been positioned
on the foundation pad, set in place and connected to the gas or LP line
outside your home or business (3-ft clearance is required on all four
sides of the unit), an automatic transfer switch is installed next to
your distribution panel.
With an air or liquid-cooled system, once the owner has selected the
circuits to protect, those circuits from the main distribution panel
to the transfer switch's load center circuits are matched. Larger generators
can protect all circuits with the appropriate transfer switch.
In operation, the system monitors incoming voltage from the utility
line, 24 hours a day. When the utility power has been interrupted, the
transfer switch senses the problem and signals for the generator to
start. At that time, the automatic transfer switch will then safely
close off the utility line and open a new power line from the generator.
Within seconds your home standby system will begin supplying electricity
to your pre-selected circuits. When the line voltage has returned at
a steady state, the transfer switch will re-transfer the electrical
load back to the utility source and resume monitoring for subsequent
