Handling
&
Storage
Lifting
and
Moving
There
are a
number
of
methods that
can
be used
in
handling
the
switchgear
which
,
when
properly
employed
,
will
not
damage
the
switchgear
sections
.
The
handling
method used
will
be determined
by
conditions and available
equipment
at
the installation
site
.
Lifting
with
a crane
is the
preferred
method
of
handling
;
however
,
overhead
obstructions
or
low
ceilings
often
dictate
the method
to
be
used
.
Rollers
,
jacks
or
fork
lift
trucks
may
be used
prior
to
removal
of
wooden skids
.
A
WARNING
Heavy

Can
result
in
death
,
serious
personal
injury
or
property
damage
.
Observe
all
handling
instructions
in

,
where
a crane
cannot
be
used
,
move
switchgear
with
rollers
,
cribbing
,
jacks
and other such
equipment
as
may
be
required
to meet
the situation
.
Forklift
trucks
should
be used
with
discretion
as
improper
lift
points
could
cause
extreme
damage
to
equipment
.
For
this
reason
,
use
of
a
forklift
truck
to
handle
or move
switchgear
is
not
recommended
.
Jacks
may
be used
to
lift
switchgear
which is
properly
supported
by sturdy
timbers
.
To
prevent
distortion
of
the
cubicles
,
rollers
and
cribbing
of
equal
height
must
be
used
in
sufficient
number
to
evenly
distribute
the load
.
Figure
3
shows
a
method
of
using jacks
on
indoor
switchgear
to
facilitate
the
use
of
rollers under
the

.
Care
must
be
used
to
prevent
damage
to
instruments
,
relays
,
and devices
,
and
to
maintain the
stability
of
the timbers
.
Remove
rollers and lower
the
switchgear
carefully
.
Leave
wooden
skids
(
when
provided
)
in
place
during moving
operation
until
final
location is reached
.
Each
group
of
switchgear
has
provisions
for
attaching
lifting
equipment
.

all
are
designed
for
use
with
a
crane
of
adequate
height
and
capacity
.
To
estimate the
maximum
required
crane
capacity
,
multiply
the number
of
sections
to
be
lifted
by
5300
pounds
(
2400
kg
)
.
A
drawing
pocket
(
or
holder
)
is
provided
on
each
lineup
of
switchgear
.
This
drawing
pocket
includes
a
general
arrangement
drawing
of
the
switchgear
lineup
,
plus
a
drawing
with
installation and
handling
instructions
for
the
equipment
.
The
drawing
pocket
is
normally
located
at
the
left
end
of
the
lineup
.
Review this
information
carefully
before
moving
the
equipment
.
Indoor
Switchgear
Before
removing
the
protective
packing
materials
,
indoor
equipment
may
be moved
by
crane
with
lift
cables attached
through
the
packaging
to
the
lifting
bars
on
the
top
of
the
switchgear
.
If
crane
facilities
are
unavailable
,
or
if
tight
spaces
prevent
use
of
a crane
,
rollers under the skids
may
be used
.
Lifting
Indoor
Switchgear
with
Crane
Recommended
lifting
of
indoor
switchgear
is
by
means
of
lifting
cables connected
to
an
overhead
crane
.
The
lifting
cables
are
connected
to
the
eyes
in
the
top
lifting
bars
.
One
set
of
lifting
bars is located
near
the
front of
the
switchgear
,
while another
set
of
lift
bars is
located closer
to
the middle
of
the
switchgear
,
as
illustrated
in
Figure
2
.
A
crane
with
sufficient
height
should be used
so
the load
angle
(
from
horizontal
)
on
the
lifting
cables
will
be
at
least
45
degrees
,
when
viewed
from
the
front
or
the
rear
.
A
lesser
angle
could
cause
the
equipment
to
be
damaged
.
The
lifting
cables
must
have
spreaders
from front
to
rear
to
prevent
twisting
the
lift
bars
.

Special
attention should
be
given
to
the
foundation
information
contained
in
this manual
as
well
as
the
information
provided
on
the
equipment
drawings
.
Be
sure
that the
foundation conforms
to
the
requirements
described
in
this
manual and the
general
arrangement
drawing
.
Outdoor
Foundations
Whichever
type
of foundation
is used
(
e
.
g
.
,
concrete
slab
,
sill channels
,
piers
or
pilings
)
,
it
must
have smooth and
level
surfaces
.
Surfaces
supporting
the
switchgear
must
be
in
the
same
horizontal
plane
within
1
/
16
"
(
1.6
mm
)
.
If
these conditions
are
not met
,
it
will
be
necessary
to
use
shims
when
installing
the
switchgear
.
For
outdoor
switchgear
,
support
shall be
provided
at
each end and
at
the side
of
every
second cubicle
,
so
that the
span
between
supports
does
not
exceed
36
"
(
914
mm
)
.
Refer
to
Figures
8
and
10
,
and the
switchgear general
arrangement
drawing
for
locations
of
support
and
anchoring
points
.
If
pilings
are
used
,
the diameter is
to
be determined
by
purchaser
,
;
however
,
they
should
not
be less than
12
"
(
305
mm
)
diameter
for sufficient
contact
,
room
for
anchor bolts
,
and
grouting
in
of
bed
plates
(
if
used
)
.
All
shipping
splits
must
be
properly
supported
.
Any
conduits which
are
installed
in
concrete must
be
perpendicular
to
switchgear mounting
surface
.
Conduits
should
extend
a
minimum
of
6
-
3
/
4
"
(
171
mm
)
to
a
maximum
of
7
-
1
/
2
"
(
190
mm
)
above
mounting
surface
.
This
will
allow the conduit
to
enter
the
cubicle
and exclude
entry
of
water
and
rodents
.
Exception
:
If
switchgear
will
be throat
-
connected
to
a
power
transformer
,
see
"
Installing

General
Requirements
Prior
to
installation
of
the
switchgear
,
careful
design
,
planning
and
construction
of
the
foundation
or
base
on
which the
switchgear
will
rest must
be made
.
A
thorough analysis
and
careful
construction
may
alleviate
many
problems
at
the
time
of
installation
,
and
during
operation
.
It
is
important
that
a
true
and level
surface
be
provided
,
capable
of
supporting
the
weight
of
the
switchgear
and other related
equipment
.
If
the
switchgear
cannot
be lowered
over
conduits
because
of
headroom
or
other
restrictions
,
conduit
couplings
may
be
grouted
in
flush
with
foundation
,
and
conduit
nipples
added
after
the
switchgear
is
in
place
.
Conduits
should be
capped
during
construction
to
prevent
entry
of
dirt
,
moisture and vermin
.
All
sill channels
,
bed
plates
,
shims
and
anchoring
hardware
are
furnished
by
purchaser
unless covered
by
contract
.
Indoor
Foundations
As
it
is
difficult
to
obtain
a
true
and level
floor
on a
concrete
slab
,
it
is
highly
recommended that
4
"
(
minimum
)
sill channels be
grouted
into
the
floor
as
shown
in
Figure
7
.
The
surface of
the
sills should
be
slightly
above
floor
level
.
The
surfaces of
the
sills
must
be level
and
in
the
same
horizontal
plane
within
1
/
16
"
(
1.6
mm
)
.
There should be
no
projection
above this
plane
within
the
area
covered
by
the
switchgear
.
If
the
floor
or
sills
do
not
meet
this
requirement
,
it
will
be
necessary
to
use
shims when
installing
the
switchgear
on
the
mounting
surface
.
Figure
7
illustrates the location
for
sill channels
for
anchoring
indoor
switchgear
.
Cubicles
may
be
anchored
to
sills
by
use
of
1
/
2
"
(
or
12
mm
)
diameter
anchor bolts
,
or
welded
in
position
.
Important
:
In
the
switchgear primary
entrance
area
,
steel
reinforcing
rods
or
mesh
in
concrete must not
pass
through
the
space
shown
on
the
general
arrangement
drawing
,
even
though
cored
or
bored holes
in
concrete
may
miss rods
or
mesh
.
A
single
phase
of
a
system
should
not
be
encircled
by
ferrous
metals
.

Installing
Shipping
Sections
The
proper
method
of
installation
depends
on
whether the
switchgear
has been
shipped
as one
complete
group
,
or
in
two
or more
shipping
sections
.
The
general
arrangement
drawings
will
indicate the
shipping
sections
,
cubicle numbers and their
location
within
the
switchgear
lineup
.
Sections
are
assembled
and wired
in
accordance
with
the
arrangement
as
in
the
final
installation
.
Before
setting
and
erecting
the cubicles
,
determine the
correct
location
of
each
shipping
group
on
the
general
arrangement
drawing
.
Sweep
the
mounting
surface
to
remove
all dirt and debris
.
If
the
transformer
must
be
positioned
first
,
conduit
couplings
should be
provided
in
the
switchgear
foundation
,
so
that the
conduits
do
not
extend
more
than
approximately
2
"
(
51
mm
)
above the
switchgear
mounting
surface
.
The
switchgear
should
be
positioned
near
the
transformer
,
and
just high enough
to
clear the
secondary
conduits
,
but low
enough
that the throat
on
the
switchgear
will
clear the
opening
in
the
transformer
terminal chamber
(
throat
)
.
When the
switchgear
is
properly
positioned
so
that the
switchgear
throat
will
fit
into the
transformer
throat
,
move
the
switchgear
toward
the
transformer
until
the
switchgear
throat extends
approximately
2
"
(
51
mm
)
into the
transformer
throat
,
and
the
switchgear
anchor bolts
and
conduits
are
correctly aligned
.
With
all
points
now
in
alignment
,
conduit
caps
and
floor
plate
conduit
covers
removed
,
carefully
lower the
switchgear
into its
permanent
position
.
After
all
leveling
and
anchoring
operations
for
the
switchgear
are
complete
,
draw the
sliding
throat
collar
of
the
switchgear
throat into
place
against
the
transformer
throat
.
Tighten
the throat hardware
only
enough
to
compress
the
gasket
.
Installing
Switchgear
with
Throat
Connection
to
Power
Transformer
When
a
transformer
is connected
to
switchgear using
a
throat connection
,
the
switchgear
should be
positioned
next to
the
transformer
as
shown
in
Figure
11
.
It
is
very
desirable
that the
switchgear
be
placed
in
position
before
positioning
the
transformer
.
