Damage
All
equipment
leaving
the
factory
is
carefully
inspected
and
packed
by
personnel experienced
in
the
proper
handling
and
packing
of
electrical
equipment
.
Upon receipt
of
any
equip
-
ment
,
immediately
perform
a
visual
inspection
to
ascertain
if
any
damage
has been
sustained
in
shipping
or
if
there
are
any
loose
parts
.
All
circuit
breakers
are
shipped
separately
in
individual
con
-
tainers
with
the
breaker
in
the
open
position
.
Circuit

ers
should
be
unpacked
and
visually
inspected
for
damage
or
loose
parts
as soon
as
possible
after
they
have been
received
.
Be
sure
to
inspect
all
devices
mounted
or
packed
inside
compartments
of
each section
to
see
if
any
have been dis
-

Handling
Utilize
four
equal
length
cables
and
an
overhead
crane
,
each
with
a
minimum
load
rating
of
twice
the
weight
of
the
switchgear
.
Example
:
Switchgear
Section
Weight
=
5
,
000
pound
.
The
crane
and
the
four
lift
cables
must
have
a
minimum
load
lifting
capacity
of
10
,
000
pounds
.
NOTE
:
It
is
preferable
to
leave
the
shipping
skids
in
place
under
the
switchgear
until
it
reaches
its
final
location
.
The
equipment
should
be
installed
in
its
final
location
prior
to
installing
the
circuit
breakers
.
NOTE
:
The
angle
between
the
cables
and
the
top
of
the
equipment
must
be
at
least
45
degrees
.
If
this
is
not
possible
because
of
lack
of
headspace
,
spreader
bars
must
be
used
.
Also
,
lift
cables
with
greater
load
capability
may
be
necessary
,
depending
upon
the
angle
between
the
cables
and
the
crane
hook
.
A

Lifting
The
switchgear
sections
are
best
handled
by
lifting
with
a
crane
as
shown
in
Fig

.
Removable
lifting
plates
are
pro
-
vided
,
as
standard

,
on
the
top
of
each

section
.
To
preserve
the

appearance
of
the

ment
,
it
is
suggested
that
the
lifting
plates
be
left
in

must
be
bolted
together

Take
up
the

very
carefully
and
man

stabilize
the
switchgear
to
prevent
it
from

NOTE
:
Do
not
attempt
to
lift

Position
one
man
in

one
man
in

to
stabilize
the

Methods
of

side
support
timbers
must
be
placed
along
the
sides
to
prevent
any
damage
that
could be
caused
by
the
lifting

.
In
addition
,
a
spreader
bar
must
be
inserted
between each
lift
cable
,
both
front

above
the

as
shown
in

Proceed
to
lift
and
place
the
outdoor
switchgear
utilizing
all
the
precautions
and
requirements
that
apply
to
lifting
the
indoor
switchgear
.
The
lifting
plates
,

should
be removed
after
the

is
permanently
anchored
so
passageways

will
not
be
obstructed

of
ventilating
air
to
the
