Secondary Disconnect Bullets for AKR 30/50 retrofill Breaker
For AKR 30/50/75/100 AKD6 retrofill breakers
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 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
Emax 2 Retrofill ACB, which runs across the width of the Emax 2 Retrofill 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.
8. Verify that the wire markers are clearly visible and not damaged so that they are wired
easily and efficiently.
9. Be careful that that the wires are not pinched or damaged while installing the secondary
disconnect blocks.
For AKR 30/50/T50/75/100 AKD6 retrofill breakers
1. If the Emax 2 retrofill breaker order included (3) 7 pt. secondary disconnect blocks, see
step 2 otherwise skip past the wiring instructions.
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 are spring-loaded and return to their initial
positions when they are released from being pressed down.
3. Check for electrical continuity between the bullets on one end 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 Emax 2 ACB, which runs across the width of the Retrofill Emax 2 ACB.
5. Align the three holes on the face of the supplied secondary block to the three holes on the
plate and secure the block to the plates using the hardware provided as mentioned above.
The screw tightening torque should be in the range of 77 to 93 in-lbs.
