HOW TO
DISCHARGE
STORED
ENERGY
WITHOUT
CLOSING
BREAKER
As
a
safety
feature
,
it
is
possible
to
locally
discharge
the
breaker
’
s
stored
energy
without
closing
the
breaker
.
This is
possible
in
both
manually
and
electrically
operat
-
ed
breakers
.
Control
power
to
the
electrical
operator
must
be
removed
to
prevent
undesired
recharging
.
The
action
involved
in
releasing
the
stored
energy
without
closing
the
main
contacts
causes
an
abnormally
high
shock
condition
on
the breaker
and
should
be
avoided
except
for
emergency
reasons
.
To release this
stored
energy
when
the
breaker
is
in
the
“
OPEN
”
position
:
First
,
depress
and
hold
the
PUSH
-
TO
-
OPEN
pushbut
-
ton
and then
depress
the
PUSH
-
TO
-
CLOSE
pushbut
-
ton
.
When
the breaker is
in
the
“
CLOSED
”
and
“
CHARGED
”
position
,
the
above actions
will
simultaneously
open
the
breaker
and
discharge
the
stored
energy
.

HOW
TO
CLOSE
SHOULD
THE
LOCAL
“
PUSH
-
TO
-
CLOSE
”
BUTTON
BE
ACCIDENTALLY
DEPRESSED
WITH
THE
BREAKER
IN
THE
“
CLOSED
”
POSITION
AND WITH
THE
MECHANISM
“
CHARGED
,
”
THE
ENERGY
WILL
BE
RELEASED
AND THE
BREAKER
COULD
“
SHOCK
”
OPEN
.
THEREFORE
,
CARE
SHOULD
BE
EXERCISED
TO AVOID
THIS
OPERATION
.
All
that is
required
to
close the
breaker
locally
is
to
push
the
mechanical
“
PUSH
-
TO
-
CLOSE
”
pushbutton
.
Precharged
breakers
may
be
closed
remotely
via
a
spring
release
solenoid which
is standard
for
electrically
operated
breakers
and
optional
for
manually
operated
breakers
(
Section
5
-
3
)
.
For
special applications
,
local
manual
closing
may
not
be
desired
.
Provisions
are
available
in
the
form of
a
manual
closing blocking
adapter
to
prevent
this
action
except
by
authorized
per
-
sonnel
(
Section
5
-
11
)
.
THE
STORED
ENERGY
CANNOT
BE
DISCHARGED
WITHOUT
CLOSING
THE
BREAKER
FROM
A
REMOTE
LOCATION
.
Before
attempting
to
close
the
breaker
locally
,
the
yel
-
low
stored
energy
window
must
read
“
CHARGED
.
”
Electrical
interlocks
are
provided
to
prevent
remote
clos
-
ing
unless the
closing
energy
is
fully
charged
and
the
mechanism
is
ready
to
be
closed
.

DRAWOUT
MECHANISM
Movement
of
the
breaker
on
its
drawout is
easily
accomplished
by
using
the
drawout
indexing
lever
and
ratchet crank
,
with
one
exception
as
described
in
Section
4
-
2.1
.
The
indexing
lever
must
always
be
lifted
before
any
drawout
movement
is
begun
,
and
it
must
be
held
until the
indexing
lever
block
clears the
slot
for
the
position
being
vacated
.
Complete
instructions
are
given
for
racking
the breaker
in
and

MOVING
BREAKER
FROM

TO
DISCONNECT
POSITION
To
move
the
breaker
from
the
“
WITHDRAWN
”
position
at
the
end
of
the extension
rails
to
the
“
DISCONNECT
'
position
,
push
the
breaker
back
on
the
rails
until the
lever
block
drops
into the
disconnect slot
.
This is the
one
and
only
time
that
the
index
lever need
not
be
lifted
prior
to
a
breaker
racking
operation
.
In
this
case
,
the
lever
cams
up
and down
automatically
.
At
this time the
extension
rails
can
be
pushed
to
the stored
position
.
The
shield
attached
to
the breaker
should
be
installed
when the breaker
is
placed
in
the
“

’
posi

tion
prior
to
its
being
racked into the
“
TEST
’
position
.
If

,
the
shield should be
removed
in
the
“
DISCONNECT

posi
-
tion
prior
to
the
breaker
being
pulled

”
repeat
the
procedure
of
lifting
the
indexing
(
ever

its
uppermost
position
and
move
the
ratchet clockwise
.
Be
certain
to
hold
the
indexing
lever
up
until the
lever
block
has
cleared
the
test
slot

position
,
lift
the
indexing
lever
to
its
uppermost
position
so
that
the lever
block
will
clear
the

bracket
.
It
is
very
important
to
always
lift
the
indexing
lever
to
its
uppermost
position
when
moving
from
one
position
to
another
.
Move
the
ratchet
clockwise
(

NOTICE
To
move
the breaker
from
“

Before
moving
the
breaker
,
remove
the ratchet
so
it
does
not
block
movement
of
the
