To connect the splices first remove the ½”-13 bolt and
washers from the left hand connection as shown in Figure
12. Rotate each phase splice counterclockwise as shown in
Figures 13 and 14, starting with the rear most splice working
forward. With all splices for a specific phase in position, as
shown in Figure 15, insert the previously removed ½”-13
bolt and washers on each phase and torque accordingly.
Refer to Table 1 for torque values. See Figures 16 – 23 for
additional information based on bus ampacity.
