BASIC
HANDLING
INSTRUCTIONS
Once
the
circuit
breaker
has
been
unbolted
and
re
-
moved
from
its
shipping
skid
,
it
should
be
turned
to
the
upright
position
and
placed
on
a
flat
surface
to
avoid
damage
to
breaker
parts
.
For
safety
,
all
handling
in
this
position
should
utilire
the
lifting

CA
-
amine
the
cartons
to
determine
if
any
damage
or
loss
was
sustained
during
transit
.
If
injury
or
rough
handling
is
evident
,
file
a
damage
claim
at
once
with
the

and
promptly
notify
the

Unpack
the

as
soon
as
possible
after
receipt
.
If
unpacking
is
delayed
,
difficulty
may
be
ex
-
perienced
in
making
a

.
Check
the
contents
of
each

before
discarding
any
packing
material
.
If
any
shortage

CLOSING
SPRING
OPERATION
The
two
closing
springs
supply
the
power
that
doses
the
circuit
breaker
and
also
charge
the
two
opening
springs
during
the
closing
operation
.
The
closing
springs
are
charged
by
a
motor
in
the
electrically
operated
breaker
and
charged
by
hand
in
the
manually
operated
breaker
;
however
,
in
either
type
,
the
springs
are
charged
the
same
amount
and
when
charged
,
the
spring
energy
is
available
to
close
the
breaker
,
thus
referred
to
as
"
stored
energy
.
”
The
closing
springs
are
normally
charged
when
the
breaker
is
opened
.
If
charged
after
closing
,
the
breaker
may
be
opened
and
then
reclosed
without
recharging
the
springs
.
In
drawout
breakers
,
the
closing
springs
are
automatically
dis
-
charged
when
the
breaker
is
moved
from
the
dis
-
connected
to
the
withdrawn
position
(
shown
in
Figure
I

.
This
prevents
accidental
