EntelliGuard R Circuit Breaker Retrofill AKD-6 Installation Manual DEH-41548 02/12
If the application requires installing all three secondary disconnect blocks, you would select the first option
above. As the secondary disconnects are already pre-installed on the breaker, wiring the secondary disconnects
can begin.
If the application does not require any secondary disconnect assemblies, you would select the second option
above. This would mean that no further wiring is needed.
If the application requires less than three secondary disconnect blocks, the customer decides on the second option
and orders the secondary disconnect blocks (bullets) as needed (
Figure 8
). Then the secondaries can be installed
and wiring the Retrofill EntelliGuard ACB can be done. Steps for installing and wiring the secondary disconnect
bullets are covered next.
Figure 8. EntelliGuard ACB Secondary Disconnect Bullets
1. Unpack the secondary disconnect block from the box. Each kit of secondary disconnect has four fixing
nuts, plain washers, and spring washers. These can be arranged on a work station to prepare for installing the
assemblies.
2. Check that the bullets, on top of the secondary disconnects, are not damaged and that they slide in to the
blocks freely. The bullets (Figure 9) are spring-loaded and retract to their initial positions when they are
released from being pressed down.
3. Check for electrical continuity between the bullets on one and the wire terminations on the other. Blocks
containing faulty bullets should be replaced.
4. Place the secondary disconnect block on top of the horizontal plate at the rear of the Retrofill EntelliGuard ACB,
which runs across the width of the Retrofill EntelliGuard ACB.
5. Align the four studs at the base of the supplied block to the four holes on the plate. The plate is provided with
three sets of four holes, one set for each block (A, B, and C blocks).
6. Slide the secondary blocks down into the plate such that the base of the secondary disconnect rests on top of
the plate.
7. Secure the studs on to the fixing plates using the hardware provided as mentioned above. The nuts must be
tightened hand-tight.
