using this assembly.
For applications using the
center bus go to step 4e.
Position the carriage bolts [17] and antiturn clips
[4] as shown in Figures 9 and 10.

to the outer bus of three-phase interiors, isometric view.
4d. Install straps. Place the G frame single straps [5,
7] over the carriage bolts and antiturn clips, as
shown in Figures 11 and 12. Place conical washers
[10] on the bolts and secure with nuts [14]. Leave
the connections finger tight.
If the group assembly selection is for connections
to the outer vertical bus with the cable
connections on the same side as the 2.75"
reference dimension, and the assembly looks like
Figure 12, then go to step 6.
4e. Strap connections to the middle vertical bus and
the vertical bus opposite the 2.75" reference
dimension.
Position the carriage bolts [17] and antiturn clips
[4] as shown in Figures 13 and 14.

4f. Install straps. Place the G frame single straps [6,
7] over the carriage bolts and antiturn clips, as
shown in Figures 15 and 16. Place conical washers
[10] on the bolts and secure with nuts [14]. Leave
the connections finger tight.
