Installation
WARNING: Before attempting to install one of these kits, remove all power from the
panelboard.
Use the following procedure to install a SG 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 Fig.no.1 or Fig.no.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. Locate the holes on the B and C phase main busbar over which C phase of breaker
mounting strap will crossover the main busbar after assembly of the breaker in
horizontal position as shown in the Fig.no.1 or Fig.no.2. Put xmas [10] tree over
the two aligned holes of B and C phase.
5. Similarly locate the holes of A phase main busbar over which B phase of breaker
mounting strap will crossover the main busbar after assembly of the breaker in
horizontal position as shown in the Fig.no.1 or Fig.no.2. Put xmas [10] tree over
the aligned hole of A phase.
6. Refer Fig.no.1 to mount the breaker on left side of interior. First mount the strap
for A phase [2] adjacent to crossbar [18] and insert the screw [7] through slot
provided for A phase to clamp it with main busbar. Similarly mount B phase [1]
strap to B phase main busbar but adjacent to A phase branch base, and C phase
[3] strap to C phase main busbar but adjacent to B phase branch base. All the
phase straps [1], [2], and [3] should be clamped with main bus using screws [7]
with 60 in-lb maximum torque.

7. Refer Fig.no.2 to mount the breaker on right side of interior. First mount the strap
for A phase [2] adjacent to cross bar [18] and insert the screw [7] through slot
provided for A phase to clamp it with main busbar. Similarly mount B phase [1]
strap to B phase main busbar but adjacent to A phase branch base, and C phase
