RECEIVING
,
HANDLING
AMD
STORAGE
Before
installing
or
operating
these circuit
breakers
,
carefully
read
these
instructions
.
the
breaker
parts
.
Be
sure
that
no
loose
parts
are
missing
or
left
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
INSTALLATION

:
Before

by
checking

DRAWOUT
BREAKERS
GENERAL
Drawout
breakers
are
manufactured
in
three
different
styles
identified
by
mounting
code letters
A
,
B
and
D
.
Code
A
break
-
ers are
employed
in AKD
-

switchgear
and
feature
closed
-

.
Code
B
breakers
provide
an
alternate
closed
-
door drawout
arrangement
with
the
stationary
element
furnished
as a
preassembled
“
substructure
”
.
Code
D
break
-
ers are
employed
in AKD
-
8
or
substructure
type
gear
and
feature
closed door drawout
.
The construction and
operation
of
each
of
these drawout
styles
is covered under
respective
headings
in
the
following
text
.
As
a
general
rule
,
breakers
of
the
same
drawout
type
,
voltage rating
and
ampere
frame
size
are
physically
inter
-
changeable
.
However
,
to
be
electrically interchangeable
with
respect
to
secondary
and
control
circuits
,
they
must
have
duplicate
wiring
.
The
degree
of
interchangeability
and
the
mechanisms
for
controlling
it
are
discussed
separately
on
page
(
14
)
-
Mote
:
The
three drawout
types
are
mutually
nonin
-
terchangeable
;
before
insertion
is
attempted
,
verify
that
the
breaker
model
matches its
intended
com
-
partment
.
LOCATION
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
.
Much better
perfor
-
mance
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
.
STATIONARY BREAKERS
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
connec
-
tions
.
The
front
cover
of
the breaker enclosure
may
be
a
hinged
door
or a
plate
bolted
to
the
panel
,
including
a
cut
-
out
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
struc
-
ture 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
.
Con
-
necting
bus and
cables
must
be
rigidly
supported
to
prevent
undue
stress
on
the breaker terminals
.
The outline
drawings
in
Table

basic
dimensional
information for
designing

This
type
drawout breaker
is
supported
by
two
protruding
pins
on
each side
of
its
frame
;
these
engage
slots
in
telescoping
slide
rails
(
tracks
)
mounted
to
each sidewall
of
the breaker
compartment
.
The door
of
the
compartment
is
hung
on
a
telescoping
inner
housing
also attached
to
the
movable tracks
.
These elements
are
arranged
so
that
the
door
moves
in
unison
with
the breaker between
the
CONNECTED
and
DISCON
-
NECTED
positions
,
allowing
the
breaker
to
be
racked without
opening

.
This

is
referred
to
as
“

WITHDRAWN
—
With
the
compartment
door
open
,
the
breaker
can
be
manually
pulled
out
to
the
WITHDRAWN
position
.
At
this
point
the
tracks
are
fully
extended and
the
breaker is
completely
out
of
its
compartment
,
ready
for
removal
.
Note that the
racking
mechanism
is
not
employed
for
movement
of
the
breaker
between
the
DISCONNECTED
and
WITHDRAWN
positions
.
The
drawout
operation
features
four
discrete
positions
:
CONNECTED
—
This
is
the breaker
’
s
“
In

”
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
discon
-
nected
but
secondary
contacts
remain
engaged
.
This
allows
complete
breaker
operation
without
energizing
the
primary
circuit
.
DISCONNECTED
—
Both
primary
and
secondary
contacts
are
disengaged
.
Breakers
can
be
racked between
the above
positions
with
the
compartment
door
closed
.
Each
of
the three
positions
is
clearly
shown
by
a

Pull
the
left
track
out
to
the
limit
of
its

;
lower
the

so
that
its
mounting

CAUTION
:
Breakers
and
tracks
are
equipped
with
rejection
hardware
which
acts
to
prevent
the
tracks
from
accepting
a
breaker
whose
rating
does
not
match
that
of
the

.
This
rejection
system
is
separately
described

Attach
the
racking
handle
to
the
racking
screw
thru
the
opening
at
the
lower
left
corner
of
the
breaker
escutcheon
.
Access
to
the
racking
screw
is
obtained
by
depressing
the
TRIP
button
and
slidingthe
racking
screw
cover
to
the
right
;
releasing
the
TRIP
button
locks
the
cover
open
.

.
Rotate
the
racking
handle
counterclockwise
(
if
possible
)
until
it
stops
,
then
remove
it
.
The
purpose
of
this
step
is
to
position
the
slotted
crank
arms
at
the
proper
angle
necessary
to
engage
the
fixed
racking
pins
in
the
compartment
.

.
Push
the
breaker
in
against
the
track
stops
.
Rotate
the
two
track
lock
links
to
lock
the
breaker
in
place
.
Close
the
door
.
10
.
Again
insert
the
racking
handle
(
as
in
Step
7
)
and
rotate
it
clockwise
until
it
stops
.
A
few
turns
before
the
stop
is
reached
,
turning
torque
will
noticeably
increase
as
the
breaker
’
s
discon
-
nect
fingers
engage
the
stationary
studs
.
The
breaker
is
now
in
the
CONNECTED
position
and
the
position
indicator
will
show
CONN
.
The
complete
racking
cycle
requires
approximately
24
turns
of
the
racking
handle
.
11
.
Remove
the
racking
handle
and
depress
the
TRIP
button
to
close
the
racking
screw
cover
.
NOTE
:
After
a
breaker
is
removed
from
its
com
-
partment
,
the
inner
house
cannot
be
manually
pushed
all
the
way
back
into
the

The
latches
that
rest

The
AKR
substructure
is
a
self
-
contained
,
open
-
type
frame
-
work
serving
as
the
stationary
receptacle
for
a
drawout
breaker
.
Featuring
closed
-
door
type
drawout
operation
,
it
is
designed
for
convenient
mounting
in
individual
breaker
compartments
of
drawout
switchgear
equipments
.
It
provides
means
for
making
the
primary
and
secondary
connections
to
the
removable
breaker
element
and
is
factory
aligned
.
All
AKR
B
-
type
breakers
for
use
in
substructures
are
equipped
with
a
“
deep
”
escutcheon
instead
of
the
standard
escutcheon
employed
on
the
A
-
type
models
.
This
configuration
allows
the
breaker
to
be
racked
between
the
CONNECTED
and
DISCONNECTED
positions
with
the
door
closed
.
The
door
is
hung
on
the
compartment
(
not
on
the
slide
rails
)
and
does
not
move
with
the
breaker
as
it
does
in
the
A
-
type
AKD
-
6
models
.
The
racking
mechanism
is
breaker
-
mounted
and
is
identical
to
that
of
the
Code
A
breaker
;
the
same
support
method
(
pins
engaging
slots
in
slide
rails
)
is
also
used
.
In
operation
,
the
substructure
traverses
the
same
four
drawout
positions
as
the
A
-
types
:
CONNECTED
—
TEST
—
DISCONNECTED
-
WITHDRAWN
.
Breaker
position
is
registered
directly
by
markings
on
the
left
side
of
the
escutcheon
,
these
becoming
visible
as
it
emerges
throught
the
door
cutout
.
