HANDLING
.
c
The
switchgear
units
are
best
handled
by
crane
.
Remov
-
able
lugs
are
provided
on
top
of
the
indoor
switchgear
.
When
using
a
crane
for
lifting
,
a
cable
spreader
must
be
used
to
obtain
a
vertical
pull
on
the
lifting lugs
.
Recom
-
mended
lifting
method
is
shown
in
Figure
1
.
CAUTION
:
IF
THE
SKID HAS
BEEN
RE
-
MOVED
,
BE
SURE
THE
ROLLERS USED
ARE
SPACED
SO
THAT
THE
THREE
CHAN
-
NELS
REST
ON TOP OF
THE
ROLLERS
,
A
DIRECT APPLICATION
OF
THE
ROLLERS
BETWEEN
THE
CHANNELS
MAY
TEAR
OR
DISTORT
THE
EQUIPMENT
.
If
practical
,
the
shipping
skid should be
left
on
the
equipment
until
it
is
at
or
near
its
final
location
.
If
crane
facilities
are
not
available
,
the
equipment
may
be
moved
into
position
by
means
of
construction
rollers
placed
under the
shipping
skid
,
Where
overhead
clearance
is
insufficient
,
the
shipping
skid
may
be
removed
and the
equipment
moved
by
rollers
placed
under the three channels
under
the
equipment
.
4
Jacks
may
also
be
used
to
handle
the
equipment
when
a
crane
is
not
available
.

Methods
of
handling
outdoor
switchgear
,
shown
in
Fig
-
ure

,
are
much
the
same
as
for
indoor
equipments
except
that
lifting
plates
are
provided
at
the
base
of
the
structure
.
The
lifting
plates
should
be
removed
after
the
equipment
is
permanently
anchored
so
that
passageway
at
the
ends
of
the
equipment
will
not
be
obstructed
.
f
,
\
If
it
is
necessary
to
store
the
equipment
for
any
length
of
time
,
the
following
precautions
should
be
taken
to
pre
-
vent
corrosion
or
deterioration
.
1
.
Uncrate
the
equipment
Check
thoroughly
for
damage
.
2
.
Store
in
a
clean
,
dry
,
rodent
free
location
with
moderate
temperature
and
provide
protective
coverings
'
to
pre
-
vent
dirt
,
water
,
or
other
foreign
substances
from
enter
-
ing
the
switchgear
.
3
.
If
dampness
or
condensation
may
be
encountered
in
the
storage
location
,
heaters
must
be
placed
inside
the
units
to
prevent
moisture
damage
.
Approximately
250
watts
of
heat
in
each
unit
is
required
.
On
outdoor
switchgear
this
may
be
accomplished
by
making
a
temporary
power
supply
connection
to
the
heaters
al
-
ready
installed
in
the
equipment
.
CAUTION
:
REMOVE
ALL
CARTONS
AND
OTHER
MISCELLANEOUS
PACKING
MA
-
TERIAL
FROM
INSIDE
THE
UNITS
BEFORE
ENERGIZING
ANY
HEATERS
.
Store
the
circuit
breakers
in
a
clean
,
dry
location
in
an
upright
position
,
They
must
be
properly
supported
to
pre
-
vent
bending
of
the
studs
or
damage
to
any
of
the
breaker
parts
.
Do
not
remove
any
protective
grease
until
they
are
ready
to
be
installed
,
A
covering
of
kraft
or
other
non
-
absorbent
paper
will
prevent
dust
from
settling
on
the
breakers
.
i
STORAGE
If
breakers
are
not
to
be
placed
in
service
at
once
,
remove
them
from
their
shipping
cartons
and
thoroughly
inspect
them
.
If
everything
is
in
satisfactory
condition
,
replace
the
breakers
in

cartons
for
storage

Each
breaker
compartment
has
four
positions
.
They
are
illustrated
in
Figure
18
and
described
below
.
1
.
CONNECTED
POSITION
—
The
breaker
is
in
operating
position
,
both
primary
and
secondary
contacts
made
and
the
door
closed
.
2
.
TEST
POSITION
—
The
primary
contacts
are
separated
by
a
safe
distance
,
but
the
secondary
contacts
are
made
.
Any
breaker
test
not
involving
power
may
be
made
in
this
position
.
The
door
may
be
closed
in
this
posi
-
tion
,
and
must
be
closed
before
charging
the
spring
on
a
manually
operated
AKR
breaker
because
an
open
door
will
interfere
with
the
breaker
handle
travel
.
3
.
DISCONNECTED
POSITION
—
Neither
the
primary
nor
the
secondary
contacts
are
made
,
The
door
may
be
closed
.
4
.
WITHDRAWN
POSITION
—
The
breaker
is
completely
out
of
its
compartment
ready
for
removal
from
the
equipment
.
The
door
must
be
open
.
NOTE
;
ALTHOUGH
THE
BREAKER
COM
-
PARTMENT
DOOR
MAY
BE
OPENED
IN
ANY
POSITION
,
IT
IS
RECOMMENDED
THAT
THE
DOOR
ONLY
BE
OPENED
WHEN
THE
BREAKER
IS
IN
THE
DISCONNECT
OR
WITHDRAWN
POSITION
.
CAUTION
;
NEVER
OPEN
THE
BREAKER
DOOR
WHEN
THE
BREAKER
IS
CLOSED
AND
IN
THE
CONNECTED
POSITION
.
These
breakers
are
supported
on
a
rollout
track
in
the
same
manner
as
the
AK
breakers
,
However
,
since
the
rackout
mechanism
is
mounted
on
the
breaker
,
there
are
no
jackshafts
in
the
enclosure
.
See
Figure
7
,
Racking
arms
on
both
sides
of
the
breaker
frame
engage
the
drawout
mechanism
pins
fastened
to
both
sides
of
the
compartment
.

Note
that
extra
items
shown
in
Figures
6
and
7
(
such
as
secondary
disconnects
,
position
switches
and
ground
sensor
secondary
disconnects
)
may
appear
in
any
compartment
or
not
be
included
at
all
,
depending
on
the
equipment
spec
-
ified
.
Also
note
that
the
bracing
for
the
primary
disconnects
shown
in
Figure
7
may
be
a
single
piece
of
insulating
material
instead
of
three
separate
pieces

A
stop
link
is
located
on
each
side
of
all
AK
breaker
compartments
.
These
links
prevent
an
operator
from
manu

pushing
a
breaker
set
on
the

all
the
way
into
the
compartment
when
the

position
.
In
a
compartment
made
for
AKR
breakers
,
the
latches
that
rest
on
the
drawout

pins
prevent
the
inner
house

to
conduits
entering
above

,
the
upper
section
contains
the
incoming

,
fed
from
the
bus

so
that
it

the
equipment
,
Lift
the
hoist
into

on
top
of
the
switchgear
so
that
the
end
with
the
single
roller
is
toward
the
rear
of
,
the
equipment
.
A
channel
is
provided
on
the
top
of
the
equipment
which
serves
as
the
track
for
the
single
wheel
on
the
rear
of
the
hoist
assembly
,
If
space
is
available
at
the
end
of
the
equipment
,
the
hoist
may
be
assembled
by
sliding
the
rear
wheel
under
the
top
leg
of
the
channel
and
then
lifting
the
front
end
of
the

is
restricted
,
the
angle
which
is
bolted

the
front
wheels
can
be
positioned
on
the
front
track

each
end
of
the
front
track
to
prevent
the
hoist
from
riding
off
the
ends
of
the
track
,
test
