Breakers with a Side Bracket
1. Drill a 3/4” diameter hole into the flux shifter
assembly mounting base to provide the necessary
clearance for the bracket. The location of the new
hole is shown in Figure 6.
2. Remove the side bracket from the frame and drill the
holes according to the pattern in Figure 4. A full-size
template is provided in the Appendix. After the holes
are drilled, return the side bracket to its original
location.
3. Mount the new flux shifter to the inside of the side
frame with the three screws, lock washers, flat
washers, and nuts supplied, as shown in Figure 5.
The upper two screws are inserted from the outside
of the frame, while the lower screw must be inserted
from the inside.
AKU-50 Breakers Only
For easier installation of the new flux shifter assembly on
AKU-50 breakers, the open-fuse lockout (OFLO) may be
removed from the breaker.
1. Remove the three bolts attaching the OFLO to the
base of the breaker.
2. The OFLO terminal block must be relocated on the
upper left side of the breaker. Some parts and tool,
not provided with the kit, are necessary for this task:
• Six strips of 14 AWG wire
• Wire splice
• 12 butt splices
• Wire labels
• Drill and size F bit
• 5 / 16 -18 tap
• Flathead screw driver
• Two 5 / 16 -18 bolts and lock washers
3. Drill and tap two holes for the 5 / 16 -18 bolts. Figure 7
shows the hole locations.
4. Remove the three bolts securing the OFLO to the
breaker and lift off the OFLO device.
5. Remove the wires that connect the OFLO device to
the terminal block.
6. Cut the wires that connect to the coils where they join
and label the wires. Attach butt splices to all twelve
open ends.
7. Connect the strands of wire to the OFLO. Mount the
terminal block in its new location. DO NOT complete
the wire connections until the flux shifter is installed.
8. Install the new flux shifter assembly as described
above and shown in Figure 5.
9. Connect the cables attached to the terminal block
and tie them together.
