Figure 4-19 Typical Circuit Breaker Shown in CONNECT
Position with Secondary Connections Made
During the levering process, the metallic primary safety
shutters in the cassette automatically move out of the way
exposing the fixed cassette stabs, thus permitting the
circuit breaker to make its primary connection (Figure
4-
20
)
.
When the circuit breaker is levered from the
CONNECT position to the TEST position, the safety
shutters automatically close over the fixed primary stabs.
A padlocking device is provided on the side of the cassette
to permit padlocking the primary safety shutters in an open
position for inspection or in the closed position to prevent
inadvertent contact with the fixed primary stabs. Padlocks
must be removed before the circuit breaker is levered in
either direction to prevent shutter system damage (Figures
3-7
,
3-8
and
4-21
)
.
To lever the circuit breaker out of the CONNECT position,
reverse the process just described for levering the circuit
breaker to the CONNECT position. Remember that the
circuit breaker must be open before the racking screw lock
plate can be recessed to gain access to the large drive nut
(Figure
4-16
)
.
Once the drive nut is accessible, engage it
with the socket and levering crank. Begin levering the cir-

cuit breaker out of the CONNECT position by turning the
crank in a counterclockwise direction. As the breaker
approaches the TEST position, the primary safety shutters
automatically cover the fixed stabs. Continue levering the
breaker to the TEST position where it will once again mate
with the front of its cradle. Refer to paragraph
4-6.3
for
instructions on how to disconnect the secondary umbilical
cord from the cassette if the breaker is to be removed from
its cassette. Disconnecting the umbilical cord will put the
breaker in the DISCONNECT position which is necessary
before removing it from the cassette.
