,
do
not meet
this
requirement
,
or
if
there
is
any
projection higher
than the
support
points
in
line
with
the base
,
shims
must
be installed
in
the
following
manner
to
provide
an
equivalent
true
surface for
switchgear
support
.
Outdoor
switchgear
groups
which have been
assembled
on a
6
"
(
162
mm
)
base
must
be
supported
along
this base
with
a
span
between
support
points
not
exceeding
36
"
(
914
mm
)
.
If
shims
are
required
,
use
4
"
(
100
mm
)
square
strips
placed
between the
bottom
of
the base
and
the
foundation
,
in
the
anchor bolt
area
where
they
will
be
clamped
firmly
in
place
.
Do
not
force

This
will
insure
