14. Lock the rails of the legacy compartment to ensure inner and outer rail movement. This will help secure
the Retrofill EntelliGuard into the compartment.

the handle.

16. Take a blade-type screwdriver, insert it in the slot or rack-out lock of the breaker ( Figure 13 ), and turn it
clockwise 45° to the right so that the racking handle shutter, inside and behind the racking hole, also
moves to the right.
Figure 13. AKD-8—Racking Tool and Screwdriver Inserted
Inserting the racking handle:
• First, insert a blade screwdriver in
the right-
hand slot and rotate it 45°
to the right.
• Then, while holding the
screwdriver torqued to the right,
insert the racking tool in the left
slot until it engages with the
machanism inside.
• After the racking tool engages,
remove the screwdriver.
17. After turning the screwdriver to the right with the shutter sliding to the right, remove the screwdriver and
insert the racking tool ( Figure 13 ) in the handle-insertion hole. It’s located on the left side. Insert this tool
so it that grabs or engages the racking mechanism inside the hole. Once the racking tool has been
properly engaged, the screwdriver can be disengaged.
18. Line up the racking tool or crank with the handle straight up so that you can get some good leverage or
torque. Then, crank clockwise so that the Retrofilll starts to move in, slowly sliding forward into the
compartment. Rotating clockwise racks the circuit breaker all the way into the enclosure.
19. As the breaker approaches the TEST position, check the alignment of the fixed and moving parts of the
secondary circuit isolating contacts.
20. Continue to rack in the breaker using the Entelliguard racking handle. Continue rotating the racking
handle clockwise until the position indicator first shows TEST, then CONNECTED.
