the large drive nut on the front of the breaker cradle. Note
that a racking screw lock plate surrounds the drive nut and
must be pushed back before the drive nut can be engaged
(Figures 4-14 and 4-16).
NOTICE
If the shoot bolt handle is not in its proper full up
Position "C" with the shoot bolts protruding fully into
the cassette's side interlock plates or if the circuit
breaker is closed while the breaker is in the CONNECT
position, the racking screw lock plate cannot be
recessed to begin the levering process. If the breaker
is closed and in the TEST position, it will trip when the
screw lock plate is pushed. In addition, the circuit
breaker will not close with the locking plate recessed.
To connect the circuit breaker, lever it in a clockwise
direction (Figure 4-17). The upper circuit breaker portion
moves into the cassette, while the lower cradle portion
remains stationary in the front portion of the cassette.
Continue levering the circuit breaker until it comes to a
definite stop position where the primary connections will
have been automatically made. This fully connected position
range is also indicated when the circuit breaker front wheel
well edge lines up with the fully connected position label on
the lower center portion of the cassette floor (Figure 4-18).
The circuit breaker is shown in the CONNECTED position in
Figure 4-19.
