Installation
Use the following procedure to install a Pro-Stock A2 circuit
breaker kit into a ReliaGear lighting panelboard. Call-out
numbers in the illustrations and numbers in brackets in the text
refer to the Item Numbers in Tables 1, 2, and 3. Subassembly of a
two-pole breaker is illustrated in Figure 3. Subassembly of a
three-pole breaker is illustrated in Figure 4. Installation of a
single-phase, two-pole kit is illustrated in Figure 5. Installation of
a three-phase, three-pole kit is illustrated in Figure 6. Installation
of a three-phase, six-pole kit is illustrated in Figure 7.
WARNING: Danger of electrical shock or injury. Turn
OFF power ahead of the panelboard before working
inside the equipment or removing any component. Do
not remove circuit protective devices or any other
component until the power is turned OFF.
1. Remove the interior assembly from its packaging and verify
that all parts are present, as given in the packing list.
2. Remove the four screws (225 A panels) or eight screws (400 A
and 600 A panels) securing the shield to the panelboard
interior. Lift off the shield 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. Subassembly circuit breaker:
a) Wrap mounting bracket insulation [17] around the mounting
bracket [11].
b) Align breaker mounting holes with the mounting bracket and
insulation assembly.
c) Fasten the breaker to the mounting bracket using the
two hex socket screws cap SCR, M4Xs5 [9].
d) Fasten the Z-Strap [12] to the breaker using M8 narrow flat washers
[15], M8 lock washers [14], and M8X25 screws [13].
e) Place the phase barriers 80mm [16]. (Figure 3 and 4 for
reference)

5. Mount the circuit breaker base assembly (7) on the interior by
aligning the holes in the bus bars (two for single-phase, three
for three-phase) protruding from the circuit breaker base over
the two or three bolts in the bus bars of the interior assembly.
Secure with two or three 5/16-18 nuts [4] tightened to 100-120
lb-in.
6. Drop the breaker subassembly (19). Align the Z-strap on the
breaker assembly over the strap inside the plastic base. Hand-
tighten self-rolling screw [2] to locate the breaker assembly. On
the other side, align the mounting bracket on the breaker
assembly over the interior rail holes. Once aligned tighten the
two #10-32 screws [5] to 27-36 lb-in. Tighten the self-rolling
screw [2] to 42 lb-in. Z-strap
a) For 6 poles kit, place phase barrier [6] between breakers
7. Install low terminal cover [18] on lug side (one for 2 and 3 poles,
two for 6 poles).
8. Install the shield insert according to the type of breaker
installation as follows:
a) If this is a main breaker installation (kit MBA12 or MBA13),
place the shield insert [1] over the shield so that the four
same-size holes line up with the threaded holes in the shield,
as illustrated in Figure 2. Fasten the shield insert to the shield
with four #10-32 x 3/8 screws [3] tightened to 27-36 lb-in.
Attach the MAIN label [10] to the front of the shield insert, as
shown in Figure 2.
b) If this is a subfeed breaker installation (kit MBA12 or MBA13)
into a 225 A panel, remove the remaining blank in-sert from
the shield. Place the new shield insert [1] supplied with the kit
over the shield so that the four same-size holes line up with
the threaded holes in the shield, as illustrated in Figure 2.
c) If this is a two- or three-pole subfeed breaker installation
(kit MBA12 or MBA13) into a 400 A or 600 A panel, remove the
two blank inserts from the shield, as illustrated in Figure 3.
Install the new shield insert [1] supplied with the kit over the
shield so that the four same-size holes line up with the
threaded holes in the shield. Fasten the shield insert to the
shield with four #10-32 x 3/8 screws [3], tightened to 27-36 lb-
in. Reinstall the bent insert removed earlier over the top of the
new insert, securing it with the screws removed with the
insert, tightened to 27-36 lb-in.
d) Fasten the shield inserts to the shield with six #10-32 x 3/8
screws [3], tightened to 27-36 lb-in.
e) If this is a six-pole subfeed breaker installation (kit MBA16)
into a 400 A or 600 A panel, remove the two blank inserts
from the shield. Install the new shield inserts [1] supplied with
the kit over the shield so that the six same-size holes line up
with the threaded holes in the shield. Install the flat shield
insert first, then the bent insert.
9. Reattach the shield to the interior with the four or eight screws
removed in Step 2. Tighten the screws to 27-36 lb-in.
