without the extension rails in place.
Checking pan operation:
A. To operate the breaker at this time (test position
mode), it is necessary to connect the secondary
harness with the breaker.
Manual secondary: For a manually engaged secondary
harness, Pull the secondary plug handle forward until the
secondary receptacle located on the compartment
levering pan fully mates with the secondary breaker
wiring plug.
Automatic secondary: For an automatically engaged
secondary harness, rack the breaker into the test
position identified by the Breaker position indication (BPI)
label.
In these positions, the breaker control circuit can be
tested offline. (Breaker is not connected to the primary
circuit.)
B. Movement of the breaker from the Disconnect or Test
position to the Connect position.
1. As the breaker is racked from Disconnect or Test, it
will automatically open if it is closed.
2. To prevent damage with a manually engaged
secondary, the breaker secondary control plug
must be manually engaged with the receptacle on
the compartment levering system, before the
breaker is moved to the connected position.
3. Rotate the levering crank in a clockwise direction
until the torque limiter on the levering crank "breaks
free." As a check, the red indicator on the levering
system can be seen through the window on the
front of the levering system, or until the breaker
cover plate aligns with the connect position location
given on the BPI label (item 7) if so equipped.
C. Movement of the breaker from the Connect position to
the Disconnect or Test position.
1. As the breaker is racked from Connect, it will
automatically open if it is closed.
2. Insert the levering crank onto the hex drive nut on
the levering system. In order to engage the hex
drive nut, you must push in the levering system
slider.
3. Rotate the levering crank in a counter-clockwise
direction until the breaker is in the Test or the
Disconnect position.
Note: The breaker secondary control receptacle on the
compartment levering system is automatically disengaged from
the breaker secondary plug when moved to the disconnect

DO NOT USE ANY TOOL OTHER THAN THE
LEVERING-IN CRANK PROVIDED TO LEVER THE
CIRCUIT BREAKER FROM TEST OR CONNECTED
POSITIONS. CORRECT OPERATION OF SOME OF
THE INTERLOCKS IS DEPENDENT ON USE OF THE
PROVIDED LEVERING CRANK. PERSONAL INJURY
OR EQUIPMENT DAMAGE COULD RESULT FROM
THE USE A TOOL OTHER THAN THE PROPER
LEVERING-IN CRANK.
NOTICE
The circuit breaker and integral levering mechanism
includes all necessary interlocks that when inter-
faced with a compatible structure will render the
circuit breaker mechanism
electrically trip-free during the levering process. For
information pertaining to individual interlocks, refer
to paragraph 4-9 in this section
To move the circuit breaker to the CONNECTED
position, engage the levering-in crank with the structure
mounted levering shaft (Figure 4-6). Turn the levering-in
crank in a clockwise direction and the circuit breaker will
move slowly toward the rear of the structure. When the
circuit breaker reaches the CONNECTED position, it will
become impossible to continue turning the levering-in
crank. The CONNECTED position will also be indicated
by a red flag indicator just below the levering device. If a
spin-free levering-in crank is being used, it will spin free
once the CONNECTED position is reached. Secondary
contacts will automatically engage if not already engaged
manually in the TEST position.
