• Bolt-on and single bus of plug-in assemblies, switchboard
panels, and powerpanel. Before installing, 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 3. The cable terminals will be mounted
on this side of the bus.

For each phase install a
/4-20 x 2" carriage bolt
[29] into a .281-inch square hole of the interior
vertical bus, as shown in Figure 4. Use the
5
uppermost holes in the 7X (9
/8") space that the
TVSS unit can reach. Slide a terminal of the cable
assembly [21] onto each carriage bolt and rotate it
so that the terminal barrel is located below the front
1
edge of the vertical bus. Install a

[24] and a
/4-20 nut [27] onto each bolt and
/4" spring washer
tighten to 75 in-lb.
• Plug-in assemblies, switchboard panels, and panelboards
with .281-inch square holes available (double bus). For
each phase, slide a spacer [22] between the vertical
1
bus bars and install a
/4-20 x 2" carriage bolt [29]
into a .281-inch square hole located towards the
front of interior vertical bus, as shown in Figure 5.

interior vertical bus, as shown in Figure 6. Use the
5
uppermost holes in the 7X (9
/8") space that the
TVSS unit can reach. Slide a terminal of the cable
assembly [21] onto each carriage bolt. Install a
3
