Installation guidelines
3. Tighten the four M12 bolts. For easiest
installation, use a long ratchet extension that
extends outside the front of the wireway and an
18 mm socket with a universal joint. Torque to 52
ft-lbs (70 Nm). Use only the fasteners provided
for busbar connections. Do not use additional
locking fluid.
4. Once torqued to the proper value, draw a line
across each fastener head and the surrounding
metal surface so you can visually check whether
the fastener has been properly torqued.

Repeat this process for all splice kits, including the
neutral bus if provided. You must splice the
horizontal ground bus between adjacent sections
in the cable compartment. Splice links are provided
on the right-hand side of each section for neutral
and Phase A, and on the left-hand side for Phases B,
C and the ground. The links may be loosened and
bridged to the adjacent section.
Note: The holes at the ends of all busbars ensure
adequate adjustment within the required
tolerances. If the lineup has been installed properly,
the busbars in adjacent sections will line up. Never
drill or modify busbars if alignment is poor. Ensure
that the adjacent sections are properly and
completely connected together mechanically
before connecting the horizontal bus splices.
Do not clean the contact surfaces on new
switchgear.
Refer to the Torque Table for all tightening torques
for horizontal bus bolted connections.
