Figure 9. AKD-10—Racking Tool
14.
Use a blade-type screwdriver in the slot or rack out lock of the breaker (
Figure 10
), and turn it clockwise
to the right so that the racking handle shutter opens
Figure 10. AKD-10—Racking Tool and Screwdriver Inserted
Inserting the racking handle:
•
First, insert a blade screwdriver in
the right-
hand slot and rotate it
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.
15.
While turning the screwdriver to the right with the shutter open, insert the racking tool in the handle
insertion hole so that it engages with the racking mechanism, and remove the screwdriver (
Figure 10
).
16.
With the racking tool inserted crank clockwise so that the Retrofill starts to move in, slowly sliding
forward into the compartment. Rotating clockwise racks the circuit breaker all the way into the
enclosure.
17.
Rotating clockwise ~37 turns racks the circuit breaker all the way into the enclosure.
18.
As the breaker approaches the TEST position, check the alignment of the fixed and moving parts of the
secondary disconnect contacts. If a spring charging motor or under voltage-release is installed, these
may operate when approaching the TEST position.
19.
Continue rotating the racking handle clockwise until the position indicator first shows TEST, then
CONNECTED.
20.
When approaching the CONNECTED position, more torque for turning the racking handle is normal as the
primary finger clusters engage with the AKD-10 primary bus stabs.
