Drop boxes
The internal electrical busways provide a location to connect each of the drop boxes, which then power the PDUs. For each IT section, stagger the drop boxes on the electrical busways by connecting one drop box to busway #1 and connecting the next drop box to busway #2. A staggered configuration allows for load balancing with the rack equipment and is necessary to create redundancy.
