Converting from 2-Load to 4 or 6-Load
This requires that new load shunt bus kits be added to existing panels in the cabinet and
linking bus bars between panels be removed or “split” to create the additional loads.
The following steps describe this procedure.
Caution: Live potentials are present within a working BDFB/ BDCBB cabinet! Take
proper precautions to insulate all tools and prohibit any live surface from contacting
framework or any other grounded surface.
Note: If splitting existing loads within the BDFB/BDCBB, the load shunt assembly
will be at a live potential as soon as it comes into contact with a distribution panel
bus and must not be allowed to contact framework or any grounded surface during
or following this step!
1. Remove 6-32 screw securing shunt wires to the charge bus bar where the new
load shunt bus assembly will be installed. Note color of shunt wires at each
position.
2. Install load shunt bus assembly to the charge bus as shown in Figure 22. Connect
(2) red glastic standoffs to panel. Attach shunt detail to panels charge bus with
5/16 hardware provided and ½” socket (Torque to 135 in-lb) and attach to
standoffs with 1/4-20 screws provided and 7/16” socket (Torque to 65 in-lb).
3. Connect shunt wires to shunt. There should be a solid color like Blue, Orange,
Gray or Brown and a striped color like White-Blue, White-Orange, White-Gray or
White-Brown. Attach solid color to back connection (it is connected to input
bus). Attach striped color to front connection (it is connected to panels charge
bus).
4. Remove Bus Bar Straps to “split off” these panels as individual load buses.
Remove 5/16” hardware with ½” socket. Store these links in hardware bin in
back of cabinet.
5. The VIM1 meter needs to be reconfigured. Navigate to
Menu
►Load Parameters ►Number of Loads and set the number of load shunts
in the BDFB.
6. Relabeling might also be required as discussed in Section 8. Stamp or Label new
load designations on the labels.
