Installation
CAUTION: For Spectra APNB bolt-on–style
interiors, locate the side of the panel interior
for which the dimension from the nearest
vertical bus face to the inner face of the bus
support rail is 2.75 inches, as indicated in
Figure 2. The circuit breaker straps must be
mounted on this side of the bus.
1. Install circuit breaker straps. Install the straps
beginning with phase A, as shown in Figure 1 and
Figure 2. Align the outer [1] and inner [2] straps
back to back, as shown. Slide the square hole in the
antiturn clip [15] over the square shank of the
carriage bolt [4], then insert the pin section of the
clip through the circular hole in the strap assembly,
with the bolt extending through the square hole
immediately below. Fasten the complete strap
assembly loosely to the vertical bus, using a Belleville
washer [5] and nut [6]. Repeat the procedure for
the phase B straps [3] and the phase C straps [1, 2].
2. Install the cover supports. Using the uppermost slot
on each cover support body, slide the cover supports
(included in the breaker cover kit), with their
mounting tabs oriented inward, onto each barrier
mounting bracket [7] until they snap into place.
The cover supports can be easily removed by
inserting a screwdriver into the mounting slot on the
underside of the mounting bracket assembly and
gently prying downward while pushing off the cover
support.
3. Install bus barrier and breaker mounting brackets.
Attach the barrier mounting brackets [7] to the
panel side rails with the thread-forming screws [8],
as shown in Figure 1. Place the barrier [9] over the
straps, with the flanges resting on the mounting
brackets. Place the breaker mounting brackets [10]
over the barrier and secure with the #8-32 screws to
the barrier and barrier mounting brackets. Tighten
the thread-forming screws [8] to 15–20 in-lb.
4. Install circuit breakers. Position the circuit breakers
such that the line- or ON-side terminals rest on the
straps and the opposite sides are supported by the
mounting brackets.
a. Insert the shakeproof screws [12] into the holes
in the line connections of the breakers. Align the
screws with the holes in the line straps and
secure loosely.
b. Align each breaker parallel to the unit, then
fasten the breakers to the brackets with the #8-32
x 3 1 /
8
" screws [13] and lock washers [14] and
tighten to 15–20 in-lb.
c. Tighten the line screws to 27–32 in-lb. Note that
the straps may require minor adjustments for
proper hole alignment.
5. Tighten bolted connections. Tighten the bolted
strap connections at the vertical bus to 65 in-lb. It
may be necessary to remove the adjacent circuit
breakers to allow access to the bolted connections at
the vertical bus.
