2. Install TVSS bus cable assembly.

• Bolt-on and single bus of plug-in assemblies, switchboard
panels, and powerpanels. 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

1

/4-20 x 2" carriage bolt

[17] 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 [9] 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

1

[12] and a

/4-20 nut [15] 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 [10] between the vertical

1

bus bars and install a

/4-20 x 2" carriage bolt [17]

into a .281-inch square hole located towards the
front of the interior vertical bus, as shown in Figure

5. Use the uppermost holes in the 7X (9

5

/8") space

that the TVSS unit can reach.

inch square hole located toward the rear of the
interior vertical bus, as shown in Figure 6. Use the

uppermost holes in the 7X (9

/8") space that the
TVSS unit can reach. Slide a terminal of the cable
assembly [9] onto each carriage bolt. Install a

3
