4.4 DC Inter-bay Copper
The inter-bay busbar is available in 4000A, 8000A and 12000A nominal sizing as required. Maximum continuous
load ratings are 80% due to shunt capability. All live inter-bay bus work is contained within the system cabinets. Re-
turn busbars can be factory ordered as internal for smaller systems with 12 or less large capacity circuits, or external
for systems with more than 12 distribution circuits.
Figure 20 shows 12000A buswork with internal return, which
can be expanded to include one more bay.
Table F on page 37 lists the available busbar kits and the cor-
responding drawing numbers. Typically these drawings ship with
the pre-packaged busbars for assembly at the destination.
