Installation

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

panelboard.

Use the following procedure to install a SF circuit breaker kit. Call-out numbers in the
illustrations and numbers in brackets in the text refer to the Item Numbers in Table 1.
Installation of a three-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 left side of interior. Place branch base for
A phase [2] adjacent to cross bar [13] as shown in fig.1 and insert the screw [7]
through slot provided for A phase to clamp it with main busbar. Similarly mount

B phase [1] branch base to B phase main busbar but adjacent to A phase branch
base and C phase [3] branch base to C phase main busbar but adjacent to B phase
branch base as shown in fig. 1. All phase branch bases [1],[2] and [3] should be
clamped with main bus using screws[7] with 60 in-lb. Maximum.

ASPP6SF3S, into an A-Series® II Panelboards.

5. Refer fig. no.2 to mount the breaker on left side of interior. Place branch base for
A phase[2] adjacent to cross bar[13] as shown in fig.1 and insert the screw [7]
through slot provided for A phase to clamp it with main busbar. Similarly mount
B phase [1] branch busbar to B phase main busbar but adjacent to A phase branch
base and C phase [3] branch busbar to C phase main busbar but adjacent to B
phase branch base as shown in fig. 2. All phase branch bases [1],[2] and [3]
should be clamped with main bus using screws[7] with 50-70 in-lb.

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

7. 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 terminal with the screws [5]. Take care to
assemble the screws to the spools as shown in Figure 1 or Figure 2, with the
tapped end of the spool toward the breaker terminal.

8. Place the breaker over branch base[1],[2] and [3], align the spool[4] with
protruded opening in branch bases and tighten the three ¼-28 X 1 3/8 screws [5]
installed in step 7 to 60 in-lb. Maximum.

9. Insert two screws [14] into the holes in the circuit breaker and tighten to bracket
[8] with 18-22 in-lb.

10. Remove the four screws [12] of existing filler plate from dead front where SF
breaker needs to be installed, as illustrated in Figure 3.
