CLOSING SPRING GAG INTERLOCK
An interlock is provided at either the front or rear on the

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
.

for use of the closing spring blocking device
.

44 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is withdrawn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
