Product Description
A manual transfer switch is a
device that is mounted next
to the loadcenter (distribution
panel) in the home or small
business. The manual
transfer switch is used in
conjunction with a portable
backup power generator and
serves the purpose of turning
selected circuits on and off
during a power outage. The
transfer switch panel allows
the owner to start up a
generator to restore power to
critical circuits when utility
power is not available.
The owner designates which
circuits are critical, such as
the refrigerator and certain
lights. Sometimes called
emergency power panels or
emergency generator panels,
manual transfer switch
panels provide the
homeowner or small
business owner with a safe
and easy way to continue
using electrical appliances
when the utility power
is unavailable temporarily.
Application Description
Manual transfer switches
are most often used in
residential, agricultural
and light commercial
applications. Comfort and
safety are key concerns
of many homeowners
who are dependent on
an uninterrupted supply
of electricity.
The increase in our
dependence on power is
due in part to the popularity
of home offices and in-home
health care. Various heavily
populated regions of the
United States experience
periodic power outages
due to extreme weather
conditions, such as ice and
snowstorms, heat waves,
tornadoes or hurricanes.
These regions that include
the Pacific Northwest,
Atlantic Coast and the Gulf
Coast are the strongest
markets for portable
generators and manual
transfer switches.
