is connected to the generator, there can be absolutely
no feedback from the generator to the power line or the
power line to the generator. When properly installed, the
normal ATS Control and safety system will eliminate all
paths and feedback.
To wire the automatic transfer switch into existing wiring,
first determine which circuits will be on the emergency load
circuit. If the entire load is transferred, the transfer switch
can be wired directly after the watt-hour meter and the
service entrance, providing the service entrance ampere
rating is within the transfer switch’s rated capability.
If only specific circuits are to be powered under emergency
power failure conditions, an additional distribution panel
designated “emergency distribution panel” must be
installed.
All selected emergency circuits are removed from main
distribution panels and installed in the emergency
distribution panel. The ATS is then installed between
the main panel and the emergency distribution panel.
Suggested circuits: freezer, refrigerator, furnace, emergency
lights, sump pump, emergency outlet circuits, etc. Total
running load must not exceed generator rating.
