2. Assemble splice bars to the bus work of the vertical sections as shown in

figure 8 - 13. If additional access to the splice is desired, loosen the
fastening screws and remove the bus access plate located in the vertical
wireway of the center (to the left of the splice). The horizontal bus now
is exposed to the left and right of the splice for added convenience. The
splicing kit will contain either two or four sets of hardware per splice
bar, depending on the current rating of the horizontal bus.

3. See Table A on page -14 for bus dimensions and mounting holes.

4. Tighten to torque specifications as listed in the Torque Requirements on

page -15 or tighten until the conical spring washer is flattened on the
one-piece nut and washer assembly. Do not grease or lubricate the
hardware.

5. Replace covers and plates and check all bolts and nuts for tightness.

Replace units in their respective stations.
