Double-throw
safety switches
Eaton’s double-throw safety switches are used to transfer service from a normal power
source to an alternate source, or to switch from one load circuit to another. The manually
operated double-throw safety switch provides an economical means of transferring power.
Eaton offers a full line of general-duty and heavy-duty double-throw safety switches.

General-duty
Eaton’s general-duty double-
throw safety switches are
commonly applied in emergency
power or generator applications
to reduce or eliminate the costly
impact of power loss from the
typical source in residential,
agricultural and light commer-
cial markets. All general-duty
double-throw safety switches
are non-fusible and are available
up to 400A.
A standby generator connected
to a residential wiring system
must be installed according to
the National Electrical Code.½
A double-throw switch must be
installed to isolate and discon-
nect wiring from normal utility
lines so that generator-produced
electricity is not back-fed
onto normal utility lines.
Whether normal electrical
service is disrupted by severe
weather conditions, accidents or
other issues, an Eaton general-
duty double-throw safety switch
is a critical component in your
standby generator applications.
Heavy-duty
Eaton’s heavy-duty double-
throw safety switches are
designed for commercial and
industrial applications. Fusible
switches are available through
600A, while non-fusible switches
are manufactured up to 800A.
The wiring configuration from
the factory allows a single load
to be supplied by a normal
or alternate source; however,
where necessary, the wiring can
be field modified to allow two
loads to be alternately supplied
by a single power source.
Heavy-duty double-throw
safety switches are designed
to accommodate a wide range
of accessories that can be factory
or field installed. Customized
solutions, including key inter-
locks, viewing windows and
receptacles, are also available
through Eaton’s Switching
Device Flex Center.

Double-throw heavy-duty
switching neutral safety switches
Double-throw safety switches
applied in emergency power
or generator applications may
require a switched neutral in lieu
of a solid neutral. If the neutral
of the generator is bonded
to a grounding system at the
generator, then a separately
derived system (reference NEC
250-20[D] and Exhibit 250.7) has
been created and a switched
neutral in the double-throw safety
switch is required. The switching
neutral is required to avoid the
potential for backfeeding of the
power that might occur if the
safety switch neutral is also
bonded. If the generator neutral
is brought to the service where
it is bonded and grounded, then
a non-separately derived system
has been created and a solid
neutral must be used in the
double-throw safety switch.
Most double-throw safety
switches in today’s market are
provided with solid neutrals and
are not UL listed for switching
neutral application. The market,
some utilities and local codes
are requiring the ability to break
or switch the neutral on three-
and four-pole double-throw
switches with a UL listing for that
capability. Three-pole switches
are used for single-phase
switching neutral applications,
while four-pole switches are used
for three-phase switching neutral
applications. In many cases, three-
and four-pole double-throw safety
switches are being installed in
the field with the left-most pole
being used as the switching
neutral, but the switch is not
UL listed for that application.
Eaton non-fusible three-pole and
four-pole double-throw safety
switches 30–800A are UL listed
for switching neutral application
with the proper installation of
the applicable switching neutral
bonding kit shown in the
Accessories section of this bro-
chure. Each bonding kit comes
with applicable materials, hard-
ware, instruction sheet and
adhesive-backed wiring schematic.
The bonding kits can only be
used on non-fusible double-throw
safety switches. When a bond-
ing kit is applied to a three-pole
switch, the switch becomes a
single-phase switch with single-
phase horsepower ratings.
A double-throw safety switch
with the appropriate bonding kit
installed is suitable for service
entrance use. Typically, a four-pole
double-throw safety switch is not
suitable for service entrance use;
however, with the appropriate
bonding kit installed, the four-
pole switch is suitable for service
entrance use as noted on the
device publication of the product.
Switching neutral bonding kits
can also be factory installed
by Eaton’s unique Switching
Device Flex Center. See the end
of this brochure for additional
information on the Flex Center.
