Installation

WARNING: Before attempting to install one of these kits, remove all power from the

panelboard.

Use the following procedure to install a FB circuit breaker kit. Call-out numbers in the
illustrations and numbers in brackets in the text refer to Item Numbers in Table 1.
Installation of a six-pole kit is illustrated in Figure 1 or Figure 2.

1. Remove the interior assembly from its packaging and verify that all parts are
present, as given in the parts list.

2. Remove the 8 screws (600A and 800A panels) securing the dead front to
panelboard interior. Lift off the dead front and place it and the screws aside.

3. Remove the circuit breaker kit from its packaging and verify that all parts are
present, as given in the packing list.

4. Refer fig.no.1 to mount the breaker on interior. Place branch base for A phase [2]
adjacent to crossbar [13] as shown in fig.1 and insert the screw [7] through slot
provided to mount it to A phase main busbar. Similarly mount B phase branch
base [1] to B phase main busbar adjacent to A phase branch base and C phase
branch base [3] to C phase main busbar adjacent to B phase branch base. All
phase branch bases should be clamped to main bus using screw [7] with 60 in-lb.

5. Mount bracket [8] on the interior rail with two screws [9] with 27-36 in-lb at the
location defined.

6. Place the conical washer [6] over the three ¼-28 x 1 3/8 screws [5] and insert the
screws through the holes in the top of the circuit breaker. Secure the three spools
[4] to the underside of the breaker terminals with the screws [5]. Take care to

12. If FB breaker has to be installed after SG or SF/TFJ or SE/TED/TQD as shown in
Figure 4 then gap between the breakers (dim A) has to be followed as mentioned
in Table 2. Replace the subsequent blank filler of dead front with FB filler plate
given in kit using steps 9 to 11.

13. If FB breaker has to installed immediate after crossbar as shown in Figure 5 then
