Removal
To rack from the CONNECT position to the TEST
position:
Danger: DO NOT open the breaker compartment
door until the breaker is in test positio
n.
The breaker MUST be open before starting the
removal operation.
1. Move the racking port blocking plate into the
open position.
2. Engage the racking screw with the racking tool
and rotate counterclockwise (CCW). Continue to
rotate counterclockwise from the CONNECTED
position into the TEST position.
Achieving DISCONNECTED position:
3. Open the circuit breaker door.
4. Remove the umbilical cord plug from the
receptacle to disconnect the device.
Removal from the DISCONNECTED position
with a lift truck:
1. Open the breaker compartment door.
2. Move to step 4 for floor-rolling breakers in the
bottom position.
3. Align the lift truck with the front of the frame
and push the lift truck near the frame. Insert the
platform hooks into the bottom set of slots and
use the outer slit in the platform hooks for floor-
rolling circuit breakers. Insert the platform hooks
into the top set of slots and use the inner slit in
the platform hooks for non-floor rolling circuit
breakers. The truck platform should be
horizontal, secured and aligned with the floor
or rails in the module. Set the foot brake.
4. Release the circuit breaker from the compartment
by pulling the interlock release handles toward
the center of the drawout element.
5. Pull the circuit breaker straight onto the lift
truck platform. Keep the drawout element level
as possible.
6. Align the breaker interlock tabs with the lift
truck slots. Engage the breaker interlock tabs by
returning the handles to their outward position.
7. Verify that the handles are fully outward and the
breaker interlock tabs are in the lift truck slots.
8. Raise the lift truck slightly to disengage the
platform hooks. Release the foot brake and pull
the lift truck away from the frame. Immediately
return the lift truck platform to ground level
before transport.
9. Close and latch the circuit breaker compartment
door.
Caution:
Breaker interlock tabs must
engage slots in lift truck platform
before releasing foot brake and
moving lift truck.
Lower the lift truck platform before
transporting drawout modules from
upper positions.
5.11 Auxiliary modules
Drawout compartments are provided for potential
transformers (PT) and control power transformers
(CPT). Fuses can be replaced once the drawout
element is in the disconnected and withdrawn
position.
Notice:
Remove foreign objects,
tools, debris and obstructions from
inside the module before inserting
breaker.
The procedure for insertion, withdrawing and
removal of auxiliary drawout elements is different
from the procedure for the circuit breaker. These
elements do not have a TEST position.
Insertion
To move the CPT or PT drawout element from the
DISCONNECTED to the CONNECTED position:
1. If provided, remove the padlock from the CPT
or PT module door and uncover the PT or CPT
module push/pull port.
2. If the PT or CPT element is withdrawn, use the
handles to push the PT or CPT element back into
the compartment to the disconnected position.
