There
should
not
beany

covered
by
the
switchgear
.
If
the
customer
’
s
floor
or
sills
do
not
meet
this
requirement
it
will
be
necessary
to
use
shims
when
installing
the
switchgear
on
the
mounting
surface
.
GENERAL
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
.
It
is
important
that
a
true
and
level
surface
be
provided
,
with
the
structure
being
capable
of
supporting
the
weight
of
the
switchgear
and
other
related
equipment
.
OUTDOOR
Concrete
slab
,
sill
channels
,
piers
or
pilings
,
whichever
type
of
foundation
is
used
,
must
have
smooth
and
level
surfaces
and
be
in
the
same
horizontal
plane
within
1
/
16
"
(
1
6
mm
)
.
If
these
conditions
are
not
met
it
will
be
neces
-
sary
to
shim
when
installing
the
switchgear
.
The
use
of
a
transit
to
obtain
a
true
level
during
foundation
construc
-
tion
is
recommended
.
In
any
group
of
outdoor
switchgear
support
points
shall
be
at
each
end
and
at
the
division
of
every
second
or
third
cubicle
,
however
,
the
span
between
supports
shall
not
exceed
66
"
(
1514
mm
)
,
see
Figure
4
.
If
pilings
are
used
,
the
diameter
is
to
be
determined
by
INDOOR
As
it
is
difficult
to
obtain
a
true
and
level
floor
on
a
con
-
crete

,
it
is
highly
recommended
that

It
should
be
noted
that

RECEIVING
AND
HANDLING
Page

Both
indoorand
outdoorswitchgearare
lifted
in
the
same
manner
.
Both
types
have
holes
in
the
top
of
the
equipment
for
attaching
lift
cables
.
These
lift
holes
are
located
at
the
division
of
each
cubicle
within
a
shipping
group
.
The
max
-
imum
shipping
group
is
five
cubicles
excluding
the
transi
-
tion
box
to
liquid
transformers
if
involved
(
this
is
not
con
-
sidered
a
cubicle
)
.
Lift
points
on
the
equipment
are
labeled
and
lift
connections
are
to
be
made
only
at
these
points
.
(
See
Figure
6
.
)
On
outdoor
switchgear
it
will
be
necessary
to
temporarily
remove
the
outdoor
roof
chan
-
nels
(
Figure
10
and
11
)
for
access
to
the
lift
holes
.
Be
sure
to
replace
the
roof
channels
immediately
after
lifting
to
make
the
equipment
weather
resistant
.
The
angle
of
the
lift
cable
relative
to
a
horizontal
plane
must
not
be
less
than
45
°
.
(
See
Figure
6
.
)
Also
note
the
tension
on
each
cableof
afourcable
lift
at
45
°
is
70.7
%
efficient
,
that
is
,
1
/
4
of
the
total
load
divided
by
.
707
will
equal
the
force
in
pounds
on
each
cable
.
Lesser
angles
become
more
severe
and
could
damage
the
switchgear
.
Make
certain
the
crane
used
is
of
adequate
height
and
capacity
.
If
equipment
is
shipped
without
breakers
being
installed
in
their
compartments
a
safe
estimate
of
requi
red
crane
capacity
would
be
3000
lbs
.
multiplied
by
the
number
of
cubicles
to
be
lifted
.
If
breakers
are
installed
for
shipment
,
use
4000
lbs
.
multiplied
by
the
number
of
cubi
-
cles
to
be
lifted
.
USE

Figure

Lifting
Switchgear
Indoor
and
Outdoor
Moving
switchgear
in
an
obstructed
area
where
a
crane
cannot
be
employed
can
be
accomplished
by
the
use
of
rollers
,
however
,
this
must
be
done
before
the
wooden
shipping
skids
are
removed
.
If
pipes
are
used
as
rollers
they
should
be
of
sufficient
diameter
that
they
will
roll
with
ease
without
digging
into
skids
.
In
placing
rollers
under
skids
or
removing
them
it
will
be
necessary
to
lift
switch
-
gear
shipping
group
by
either
jacks
or
fork
lift
truck
.
If
fork
lift
truck
is
used
it
must
be
used
with
utmost
caution
to
avoid
possible
damage
to
switchgear
,
and
under
no
cir
-
cumstances
are
the
points
of
lift
contact
to
be
other
than
the
following
:
indoor
switchgear
,
lift
only
on
the
jacking
angle
provided
near
bottom
at
each
end
of
the
shipping
group
.
On
outdoor
switchgear
,
lift
only
at
points
indicated
in
Figure
7
.
At
these
points
on
outdoor
equipment
there
is
a
rigid
support
base
suitable
for
jacking
.

SETTING
SHIPPING
SECTIONS
After
checking
each
shipping
section
for
its
proper
loca
-
tion
sequence
,
as
shown
on
the
general
arrangement
drawing
,
move
the
first
section
of
the
switchgear
to
its
location
.
When
a
transformer
is
part
of
the
installation
and
in
its
correct
location
,
the
switchgear
is
positioned
next
to
the
transformer
as
shown
in
Figure
16
.
The
shipping
sec
-
tion
should
be
kept
high
enough
to
just
clear
any
conduits
and
then
moved
toward
the
transformer
to
the
dimensions
shown
on
the
general
arrangement
drawing
.
At
the
same
time
align
switchgear
with
the
anchor
bolt
locations
and
conduit
locations
below
.
With
all
points
aligned
and
with
conduit
caps
and
floor
plate
covers
removed
,
carefully
lower
the
section
to
its
permanent
location
.
It
is
important
that
the
first
section
be
accurately
positioned
and
leveled
as
each
successive
section
will
depend
on
the
first
.

in
the
case
of
a
slab
or
floor
there
are
no
projections
such
as
pebbles
in
the
concrete
protruding
above
this
plane
.
This
being
accomplished
there
should
not
be
any
problem
in
plumbing
or
leveling
the
switchgear
.
Plumbing
and
leveling
outdoor
equipment
is
basically
the
same
as
indoor
.
When

Unlike
indoor
the

is
anchored
through
the
use
of
studs
or
“
J
”
-
bolts
grouted
into
foundation
and
with
clamp
washers
gripping
the
switchgear
base
.
Examine
area
adjacent
to
each
anchor
stud
to
make
certain
that
the
base
is
in
firm
contact
with
the
mounting
surface
.
If
there
are
areas
adjacent
to
these
studs
which
are
not
in
contact
with
the
mounting
surface
of
the
slab
,
piers
or
pilings
they
must
be
brought
into
contact
by
use
of
shims
.
These
shims
will
prevent
distortion
of
the
base
when
anchor
hardware
is
drawn
tight
.
With
all
points
of
contact
checked

ping
section
properly
located
tighten
anchor
hardware
.
If
there
are
additional
shipping
sections
each
one

quence
should
be
aligned
with
that
previously
anchored

Check
foundation
contact
,
plumb
and
add
shims
as
required
in
same
manner
as
first
group
installed
.
Draw
the
anchor
hardware
tight
,
install
and
tighten
the
hardware
bolting
the
sections
together
and
proceed
to
the
next
section
,
if
any
.
If
the
general
arrangement
drawing
has
been
followed
there
should
not
be
any
shipping

.
Install
roof

,
as
shown
in
Figure

PLUMBING
To
make
certain
that
there
has
been
no
distortion
of
switchgear
in
shipping
or
handling
each
shipping
section
should
be
checked
with
a
plumb
Iine
after
it
is
resting
on
its
permanent
level
foundation
.
A
plumb
line
dropped
from
the
top
front
corner
at
each
end
of
the
shipping
section
should
verify
that
the
section
is
vertical
within
1
/
8
"
(
3.2
mm
)
.
Out
of
plumb
greater
than

"
(
3.2
mm
)
usually
indicates
an
uneven
base
and
shimming
may
be
required
.

Current
transformers
for
metering
are
generally
mounted
on
the
stationary
primary
disconnect
studs
and
are
readily
accessible
for
inspection
and
replacement
.
Current
transformers
for
static
trip
device
use
are
called
“
tripping
transformers
”
.
They
have
a
one
ampere
second
-
ary
and
are
not
suitable
for
metering
.
They
are
mounted
on
the
circuit
breaker
except
when
a
ground
fault
trip
element
is
furnished
for
a
four
-
wire
application
.
In
this
case
,
a
fourth
tripping
transformer
is
mounted
in
the
cable
compartment
on
the
neutral
bus
or
in
the
link
between
the
neutral
bus
and
the
ground
bus
.
This
will
be
shown
on
the
three

diagram
and
may
require
that
the
neutral
cables
be
connected
to
it
with
the
cable
lugs
furnished
.
GROUND
CONNECTIONS
A
common
ground
bus
is
incorporated
in
all
cubicles
for
properly
grounding
the
switchgear
after
installation
.
Each
cubicle
has
a
tap
from
the
ground
bus
to
the
primary
entrance
cable
compartment
.
Provisions
for
connecting
this
ground
bus
to
the

SHUTTERS
When
shutters
are
specified
as
an
optional
item
they
are
mounted
to
the
breaker
drawout
compartment
floor
plate
.
The
shutters
automatically
close
when
the
breaker
is
removed
from
the
compartment
and
open
when
the
breaker
is
inserted
.
When
the
breaker
is
installed
on
the
sliding
rails
,
and
is
pushed
into
the
compartment
the
disconnect
end
of
the
breaker
frame
,
which
is
engaged
in
the
slide
rail
notch
,
makes
contact
with
the
shutter
operating
disc
.
Further
movement
causes
the
operating
disc
to
roll
under
the
breaker
frame
rotating
the
arm
to
which
it
is
mounted
.
The
above
action
has
partially
opened
the
shutter
which
folds
outwardly
at
the
gear
hinge
.
Further
inward
movement
of
the
breaker
causes
the
lower
portion
of
the
breakerframe
,
that
which
hangs
below
the
slide
rails
,
to
contact
the
upper
leaf
of
the
shutter
and
completes
the
opening
operation
of
the
shutter
.
In
the
process
of
withdrawing
the
breaker
from
the
compartment
,
torsion
springs
plus
a
positive
shutter
return
(
a
projecting
