Attaching switchboard sections
The manufacturer has provided hardware with the equipment to
join switchboard sections. The hardware includes 3/8” x 1” carriage
bolts and 3/8” hex nuts with captive Belleville-type washer.
(See Figure 13.)
Holes are provided on the side of each switchboard section for this
purpose. Three holes are located on the side of each section toward
the front and back. Switchboards with deep designs, including rear-
connected switchboards, may have an additional three holes for
attachment on the center vertical section support. (See Figure 14.)

Figure 15. Joining Switchboard Sections
Join sections by using the carriage bolts and hex nuts with captive
Belleville-type washer through the holes provided. (See Figure 15.)
While maintaining level and alignment of the structures, torque each
connection to the values shown in Appendix A, Table 2.
If switchboard sections are outdoor type, re-install roof cap(s).
Visually inspect the roof cap to ensure a reliable, permanent water-
tight fit prior to energizing the switchboard.
Once the switchboard structures are attached, visually inspect the
board for foreign objects and visually inspect the structure for proper
clearances of live parts.
