NOTE
:
Before
installing
or
operating
these
circuit
breakers
,
carefully
read
Sections
1
,
2
,
and
3
.
SECTION
1
—
Receiving
,
Handling
,
and
Storage
in
the
packaging
material
.
Blow
out
any
dirt
or
loose
particles
of
packaging
material
remaining
on
or
in
the
breaker
.
If
the
circuit
breaker
is
not
to
be
placed
in
service
at
once
,
store
it
in
a
clean
,
dry
location
in
an
upright
position
.
Support
it
to
prevent
bending
of
the
studs
or
damage
to
any
of
the
breaker
parts
.
Do
not
cover
the
breaker
with
packing
or
other
material
which
absorbs
moisture
that
may
cause
corrosion
of
breaker
parts
.
A
covering
of
kraft
or
other
non
-
absorbent
paper
will
prevent
dust
from
settling
on
the
breaker
.
Upon
receipt
of
a
circuit
breaker
,
immediately
examine
for
any
damage
or
loss
sustained
in
shipment
.
If
injury
,
loss
,
or
rough
handling
is
evident
,
file
a
damage
claim
at
once
with
the
transportation
company
and
notify
the
nearest
General
Electric
Sales
Office
.
Unpack
the
circuit
breaker
as
soon
as
possible
after
it
has
been
received
.
Exercise
care
in
unpacking
to
avoid
damage
to
the
breaker
parts
.
Be
sure
that
no
loose
parts
are
missing
or
left

Installation
Location
The
outline
drawings
in
Table
1
provide
basic
dimensional
information
for
designing
the
panel
or
enclosure
mounting
.
In
choosing
a
location
for
the
installation
of
these
breakers
there
are
two
factors
to
be
considered
.
The
first
is
the
location
’
s
environmental
impact
on
the
breaker
.
Better
performance
and
longer
life
can
be
expected
if
the
area
is
clean
,
dry
,
dust
-
free
,
and
well
ventilated
.
The
second
is
convenience
for
operation
and
maintenance
.
The
breaker
should
be
easily
accessible
to
the
operator
and
there
should
be
sufficient
space
available
for
maintenance
work
.

Breakers
(
Code
S
)
These
breakers
are
designed
for
mounting
in
a
switchboard
or
enclosure
designed
and
constructed
by
others
.
Mounting
consists
of
bolting
the
breaker
frame
to
a
supporting
structure
within
the
switchboard
or
enclosure
,
connecting
the
power
buses
or
cables
,
and
making
any
necessary
control
connections
.
The
front
cover
of
the
breaker
enclosure
may
be
a
hinged
door
or
a
plate
bolted
to
the
panel
,
including
a
cutout
opening
through
which
the
front
escutcheon
of
the
breaker
can
protrude
.
The
surface
on
which
the
breaker
is
mounted
must
be
flat
to
avoid
internal
distortion
of
the
breaker
.
The
supporting
structure
must
be
rigid
enough
to
avoid
any
possibility
of
the
breaker
studs
supporting
the
weight
of
the
breaker
.
Minimum
cutout
dimensions
as
given
by
the
appropriate
outline
drawing
must
be
maintained
to
provide
adequate
electrical
clearance
.
Connecting
bus
and
cables
must
be
rigidly
supported
to
prevent
undue
stress
on
the
breaker
terminals
.

Switchgear
and
Substructure
The
draw
out
breaker
is
supported
by
two
protruding
pins
on
each
side
of
its
frame
;
these
pins
engage
slots
in
telescoping
slide
rails
(
tracks
)
mounted
to
each
sidewall
of
the
switchgear
.
All
draw
out
breakers
are
equipped
with
a
deep
escutcheon
with
side
labels
showing
these
discrete
positions
:
CONNECTED
—
This
is
the
breaker
’
s
“
in
-
service
”
position
.
It
is
fully
inserted
in
its
compartment
;
the
primary
and
secondary
disconnect
contacts
are
fully
engaged
.
The
breaker
must
be
tripped
before
it
can
be
racked
into
or
out
of
this
position
.
TEST
—
In
this
position
the
primary
contacts
are
disconnected
but
secondary
contacts
remain
engaged
.
This
allows
complete
breaker
operation
without
energizing
the
primary
circuit
.
