RECEIVING
AND
HANDLING
Handling
General
Each
shipping
section
of
switchgear
is
securely
blocked
and
braced
for
shipment
.
It
is
crated
,
boxed
or
covered
as
required
by
shipping
conditions
.
Whatever
method
of
ship
-
ment
is
employed
,
every
precaution
is
taken
to
insure
its
safe
arrival
.
If
special
handling
is
required
,
it
is
so
indicated
on
the
shipment
.
All
moving
parts
are
secured
.
However
,
relatively
delicate
instruments
are
included
which
requires
that
each
section
be
handled
carefully
until
installed
in
its
final
location
.
General
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
equipment
and
method
used
will
be
determined
by
conditions
at
the
installation
site
.
Lifting
with
a
crane
is
the
preferred
method
of
handling
however
,
roller
bars
,
jacks
or
forklift
may
be
used
prior
to
removal
of
the
wooden
skid
.
Each
switchgear
shipping
section
has
provisions
for
attach
-
ing
lifting
equipment
(
see
figures
3
and
4
)
.
Though
the
lift
points
vary
in
location
among
indoor
and
outdoor
sections
,
each
is
designed
for
use
with
a
crane
of
adequate
height
and
capacity
.
To
determine
the
required
crane
capacity
,
check
the
shipping
manifest
or
multiply
the
number
of
cubicles
in
the
shipping
section
by
3000
pounds
.
NOTE
Circuit
breakers
are
shipped
installed
in
their
respec
-
tive
compartments
,
secured
in
the
fully
connected
position
,
and
closed
.
A
bolt
is
placed
through
the
trip
button
to
prevent
accidental
tripping
during
shipment
.
(
See
Figure
30
)
Identification
In
the
case
of
multiple
sections
of
load
center
substations
,
the
low
voltage
circuit
breakers
are
key
interlocked
with
the
transformer
primary
switches
.
Check
substation
numbers
on
the
packaging
of
the
switchgear
and
primary
switches
with
those
noted
on
the
applicable
General
Arrangement
and
Floor
Plan
drawings
.
These
numbers
insure
that
all
the
components
,
applying
to
a
particular
substation
,
are
cor
-
rectly
located
before
uncrating
.
Inspection
and
Uncrating
Inspect
the
shipment
as
soon
as
possible
after
receiving
for
any
damage
that
may
have
occurred
in
transit
.
Before
un
-
crating
,
examine
the
crate
itself
for
damage
.
A
splintered
crate
indicates
that
the
area
within
may
have
been
damaged
.
Be
careful
when
uncrating
the
shipment
.
The
use
of
sledge
-
hammers
and
crowbars
may
damage
the
finish
,
if
not
the
item
itself
.
Use
nailpullers
.
After
uncrating
,
examine
each
item
for
any
possible
damage
.
Check
the
shipping
manifest
to
be
certain
that
all
items
have
been
received
.
Do
not
destroy
any
packing
material
until
all
items
listed
on
the
shipping
manifest
have
been
accounted
for
.
Do
not
remove
identification
cards
from
apparatus
until
the
switchgear
is
completely
installed
.
If
there
is
a
shortage
,
make
certain
it
is
noted
on
the
freight
bill
and
contact
the
carrier
im
-
mediately
.
Notify
the
representing
Allis
-
Chalmers
sales
office
of
any
shortage
or
damage
.
Unusual
circumstances
may
require
partial
shipments
of
switchgear
.
Should
a
case
of
this
nature
exist
,
provision
is
made
for
easy
installation
of
these
portions
.

Lifting
Indoor
Sections
(
see
figure
3
)
if
used
,
must
be
timbers
of
sufficient
strength
to
withstand
the
compressive
force
of
the
cables
.
Wooden
spreaders
should
have
steel
bands
or
studs
to
prevent
splitting
.
CAUTION
Lifting
channels
on
indoor
sections
must
not
be
removed
under
any
circumstances
until
the
switch
-
gear
is
installed
in
its
final
location
.
These
channels
insure
the
true
alignment
of
the
cubicles
in
a
shipping
section
until
it
is
leveled
and
anchored
.
Moving
Shipping
Sections
Without
Crane
Within
buildings
and
obstructed
areas
where
a
crane
cannot
be
used
,
the
shipping
sections
are
moved
with
rollers
,
cribbing
and
jacks
.
These
methods
are
illustrated
in
figures
5
and
6
for
indoor
handling
and
figures
7
and
8
for
outdoor
handling
.
To
prevent
distortion
of
shipping
sections
,
rollers
and
/
or
cribbing
should
be
of
uniform
size
and
used
in
suf
-
ficient
numbers
to
evenly
distribute
the
load
.
Remove
the
rollers
and
lower
shipping
section
carefully
.
Leave
wooden
skids
(
when
provided
)
in
place
during
moving
and
until
final
location
is
reached
.
Jacking
angles
are
provided
on
either
side
of
indoor
shipping
sections
.
Four
angles
are
furnished
for
attaching
to
the
corners
of
outdoor
shipping
sections
.
Indoor
jacking
angles
are
removed
and
discarded
when
final
location
is
reached
.
Outdoor
jacking
angles
may
be
removed
when
the
jacks
are
no
longer
required
.
Lifting
channels
are
mounted
on
top
of
indoor
shipping
sections
.
They
are
normally
furnished
with
lift
point
spreaders
which
can
be
discarded
after
installation
.
The
load
angle
on
lifting
cables
must
be
at
least
45
degrees
.
A
lesser
angle
could
damage
the
shipping
section
.
Lifting
Outdoor
Sections
(
see
figure
4
)
Lift
outdoor
shipping
sections
by
attaching
cables
to
four
lifting
angles
mounted
on
the
ends
of
the
channel
base
.
Cable
spreaders
are
required
above
the
roof
of
the
shipping
section
to
protect
it
from
damage
.
Wooden
cable
spreaders
,
CAUTION
Forklift
trucks
should
be
used
with
discretion
as
improper
lift
points
could
cause
extreme
damage
to
shipping
sections
.

this
requirement
,
or
if
there
are
any
projections
higher
than
the
support
points
and
in
line
with
the

proper
loading
.
However
,
they
must
not
be
less
than
twelve
(
12
)
inches
for
sufficient
contact
with
base
,
allowing
for
space
for
shipping
split
and
space
for
grouting

if
used
.
All
shipping
splits
must
be
supported
and
taken
into
consideration
when

When
grouted
in
anchor
bolts
are
required
,
they
must
be
located
as
shown
on
the
General
Arrangement
drawing
.
Make
certain
that
all
conduits
are
perpendicular
to
the
base
plane
and
are
located
to
fit
in
the
area
provided
as
shown
on
the
General
Arrangement
drawing
.
Secondary
control
conduits
must
not
exceed
a
2
inch
nominal
pipe
size
(
2
-
3
/
8
inches
OD
.
)
.
Though
the
conduit
should
extend
above
floor
or
slab
to
enter
the
cubicle
and
exclude
water
,
it
should
not
exceed
1
-
1
/
2
inches
on
indoor
switchgear
.
On
outdoor
switchgear
the
secondary
control
conduit
should
extend
approximately
7
inches
above
the
slab
or
base
plane
but
not
exceed
a
maximum
of
8
inches
or
a
minimum
of
6
-
3
/
4
inches
.
In
cases
where
shipping
sections
cannot
be
lowered
over
the
conduit
because
of
headroom
or
other
restriction
,
conduit
couplings
can
be
grouted
in
flush
with
the
slab
.
Conduit
nipples
can
then
be
added
after
switchgear
is
in
place
.
Keep
conduit
ends
capped
during
construction
until
ready
to
make
electrical
connections
.
This
precaution
will
prevent
dirt
,
moisture
and
vermin
from
entering
the
conduit
.
If
the
primary
power
conduit
is
grouted
into
the
founda
-
tion
,
follow
the
preceding
instruction
.
(
This
conduit
may
often
enter
through
a
trench
or
planned
opening
.
)
c
Installing
Shipping
Sections
General
The
proper
method
of
installation
depends
on
whether
the
switchgear
is
shipped
as
one
complete
unit
or
in
two
or
more
shipping
sections
.
The
General
Arrangement
drawing
will
indicate
the
shipping
sections
and
their
location
within
the
line
-
up
.
Sections
are
assembled
and
wired
in
accordance
with
the
arrangement
as
in
final
installation
.
As
previously
covered
under
“
Foundation
”
,
mounting
surfaces
,
sills
,
slab
,
piers
or
piling
must
be
level
and
in
the
same
plane
.
Also
,
conduits
must
be
properly
located
and
perpendicular
to
such
a
degree
that
they
will
clear
the
floor
plate
cutouts
.
Mounting
surfaces
must
be
swept
free
of
stone
,
chips
or
other
debris
which
might
impede
rollers
or
leveling
of
the
switchgear
.
unit
and
is
controlled
by
a
switch
on
the
wall
.
Each
group
of
units
contains
a
convenience
outlet
and
switches
.
Standard
accessories
for
outdoor
units
include
all
those
provided
for
indoor
switchgear
.
In
addition
,

sections
are
in
place
,
leveled
and
securely
fastened
to
the
floor
.
Remove
rear
lifting
channel
and
install

Leveling
Indoor
Switchgear
With
the
first
section
of
cubicles
in
place
and
lifting
channels
still
rigidly
attached
,
examine
each
cubicle
through
anchor
bolt
holes
to
be
certain
that
each
point
of
anchor
is
in
firm
contact
with
sill
channel
or
floor
.
If
there
is
no
contact
,
shims
must
be
added
adjacent
to
the
anchor
bolt
holes
.
These
shims
will
prevent
distortion
of
the
section
when
anchor
hardware
is
drawn
tight
.
The
shims
should
be
approximately
four
inches
square
with
thickness
determined
by
existing
requirement
or
attained
by
stacking
.
Tighten
anchoring
hardware
and
check
for
level
.
Leveling
Outdoor
Switchgear
In
outdoor
arrangements
the
switchgear
,
as
received
,
is
true
and
in
correct
position
relative
to
its
welded
support
channels
.
These
channels
must
be
in
firm
contact
with
the
foundation
in
the
area
of
each
anchor
bolt
.
If
necessary
,
four
inch
square
steel
shims
should
be
installed
to
obtain
this
firm
contact
.
Tighten
anchor
hardware
and
