30. Continue rotating the racking handle clockwise until the position indicator first shows TEST,
then CONNECTED.
When approaching the CONNECTED position, effort to turn the racking handle increases as the
clusters engage with the cassette-mounted contacts. If a motor-spring charge or under-voltage-to-
release is installed, the device may operate when approaching the TEST position.
31. Keep cranking as required, that is, when any further torqueing can’t be done.
At this point, the fingers at the back of the circuit breaker have completely grabbed onto the
contacts at the back of the cassette.
32. Remove and store the racking handle in it storage location.
It is a good idea to keep the racking handle always in the same place for future use.
33. Note that the circuit breaker is now ready for normal operation.
Secondary Disconnects, Bullets
The circuit breaker secondary disconnects are already located on, or wired to, the breaker’s cassette.
The landing of the wiring on the EntelliGuard R breaker cassette is done in the field. Up to 78 points are
available so that all breaker accessories can be wired to dedicated
disconnect-points in the cubicle.
Each breaker wire is identified with a unique label. The wireframes in Figure 41 and Figure 42 depict the
secondary disconnect assemblies for the AKD-5 AK25/AK50. Figure 43 shows the exploded view of four
blocks of secondary disconnects. The cassette is a separate assembly from the retrofill breaker; first, the
cassette is to be wired and then installed in the switchgear, the followed by the breaker being racked
into the cassette.
