The Full-Size BDFB was designed so that its buswork and distribution
panels can be recongured at any time later on to meet the desired
needs of the customer. It is possible to recongure the buswork to
create a dual-bus, quad-bus, or an eight-bus BDFB. Figures 31-33
below represent the di󰀨erent interconnection jumper layouts that can
be achieved by simply adding or removing jumpers. For more detailed
information, refer to Appendix B for bus locations and layout.
To assemble a dual-bus conguration, install the hot/return jumpers
between all hot/return buses (see Figure 31). To assemble a quad-bus
conguration, install the hot/return jumpers on all hot/return buses
except for the middle position (see Figure 32). To assemble an eight-
bus conguration, remove all hot/return jumpers (see Figure 33). Refer
to 4.8.1 and 4.8.2 on Page 18 for detailed interconnection jumper
installation instructions.
