6. Torque all bolts on both ends to 31–32 lb-ft (41.87–43.22 Nym). See
Figure 55.

Splicing Offset Horizontal Bus
(Left Side of Structure Only)
NOTES: • In all structures with an offset horizontal bus, splice bars are
provided as a kit. This kit is packaged in a carton and shipped
inside the structure. The kit contains all splice bars and
mounting hardware necessary for horizontal bus splicing.
• Use the splice kit only if splicing is to be done on the left (while
facing the structure). If the splice is not on the left, remove the kit
before energizing and retain it for future expansion. If a structure
is to be spliced to another structure on the right, follow splicing
instructions provided for that structure application.
• All splice connections have one more splice bar than the
number of horizontal bus bars. The rear-most splice bar
contains captive nuts.
