INTERLOCK
An
interlock is
provided
at
either
the
front
or
rear
on
the
left side
of
the
breaker
frame
to
prevent
racking
in
a
breaker
which
has
the
spring
-
blocking
device
(
pin
or
plate
)
in
the
gagged
position
.
The
spring
-
blocking
device
must
be
re
-
moved
so
that
the
interlock interference
may
reset
to
allow
the
breaker
to
be
racked
.

Interference
Interlock
The second
position
for
padlocks
(
5
)
is behind
the
key
lock
.
A
padlock
in
this
slot
will
prevent
any
motion
of
the
racking
mechanism
by
keeping
the
hexagon
turning
shaft
covered
.
KEY
LOCKS
On
the
lefthand
breaker
racking
mechanism
track
is
a
provision
for
a
key
lock
.
The
purpose
of
this
lock
is
to
keep
the breaker
from
closing
in
the
“
Test
”
and
“
Connect
”
positions
by
operating
the
negative
interlock
see
Fig
.
41
.
To
remove
the
key
(
3
)
,
push
slide
(
1
)
to
the
rear
and extend
the
bolt
(
4
)
of
the lock
into
slot
.
This
allows
the
key
to
be
re
-
moved
and
prevents
the breaker
from
closing
.
The
key
lock
does
not
prevent
motion
of
the
racking
mechanism
.
STATIONARY
AUXILIARY
SWITCH
An
auxiliary
switch
can
be
provided
at
the bottom
of
the
breaker
compartment
so
that
additional
contacts
can
be
actuated
by
the
operation
of
the
breaker
.
The breaker
will
operate
this
switch
when
it
is
in
the
“
Test
”
or
“
Connect
”
position
.
See
Fig
.
45
.
BREAKER
POSITION SWITCH
PADLOCKS
A
position
switch
can
be
provided
at
the bottom
of
a
breaker
compartment
so
that
it
will
be
operated
by
a
bracket
on
the breaker
frame
when the
breaker
is
in
the
“
Connect
”
position
.
When
the breaker
is
withdrawn
,
a
spring
will
re
-
turn
the
switch
to
its
normal
position
.
See
Fig
.
45
.
Two
positions
for
a
possible
3
padlocks
each
are
provided
on
the
racking
mechanism
.
See
Fig
.
42
.
The
front
position
keeps
the breaker
from
closing
in
the
“
Test
”
and
“
Connect
”
position
.
To
obtain this
position
push
slide
(
1
)
Fig
.
42
to
the
rear
and
insert the
padlock
in
the
slotted
opening
just
forward
of
the
keylock
(
3
)
.
This
gives
the
same
interlocking
functions
as
the
keylock
and
does
not
block
the
motion
of
the
racking
mechanism
.
SPACE
HEATERS
Space
heaters
are
provided
in
all
outdoor
equipment
in
order
to
keep
the
inside
temperature
several
degrees
higher
