Installation
Inspection
RECEIVING
AND
STORAGE
Inspect
the
condition
of
circuit
breaker
vacuum
interrupters
and
electrical
connections
prior
to
installing
the
circuit
breaker
into
the
switchboard
.
Even
though
each
circuit
breaker
is
completely
adjusted
and
tested
at
the
factory
,
shipping
and
handling
condi
-
tions
could
cause
defects
.
Immediately
upon
receipt
of
the
circuit
breakers
,
examine
the
cartons
to
determine
if
any
damage
or
loss
was
sustained
during
transit
.
If
abuse
or
rough
handling
is
evident
,
file
a
damage
claim
at
once
with
the
carrier
and
promptly
notify
the
nearest
District
Office
.
The
company
is
not
responsible
for
damage
of
goods
after
delivery
to
the
carrier
,
however
,
we
will
lend
assistance
if
notified
of
claims

difficulty
may
be
experienced
in

ends
and
around

Since
a
certain
amount
of
transmitted
light
is
usually
required
to
detect
cracks
,
the
inspec
-
tion
should
be
done
in
a
well
lighted
area
.
If
the
mid
-

ring
,
when
so
equipped
,
has
been
bent
by
an
accidental
impact
,
that
area
should
be
specially
scrutinized
for

.
Small
external
chips
will
not
impair
the
useful
life
of
the
interrupter
.
Circuit
breakers
should
be
installed
in
their
permanent
location
as
soon
as
possible
.
If
the
breakers
are
not
to
be
placed
in
service
for
some
time
,
it
is
advisable
to
provide
adequate
means
of
protection
.
This
may
be
done
by
keeping
the
breaker
in
its
original
shipping
carton
and
storing
in
a
warm
,
dry
and
uncontaminated
atmosphere
.
If
the
circuit
breaker
cannot
be
stored
properly
,
it
must
be
thoroughly
checked
before
going
into
service
to
insure
it
has
not
absorbed
moisture
,
rusted
or
become
generally
contami
-
nated
in
any
way
.
Insulation
Structure
All
insulated
parts
should
be
checked
for
damage
.
Any
dust
or
dirt
should
be
removed
by
air
or
wiped
with
a
clean
lintless
cloth
.
The
lead
support
moldings
are
polyester
glass
and
occasionally
have
some
resin
rich
cracks
or
crazing
develop
.
These
do
not
indicate
defective
material
and
should
not
cause
concern
.
