Installing Straight Power Bus Splices: Dual Bar
For each power bus in the system, follow this procedure:
1. Verify that the following splice hardware is present:
2. Verify that contact surfaces are free of dirt/debris. Deburr edges as
necessary.
3.
4. Slide one flat washer and one nut/conical-spring washer over the end of
each bus-clamp screw.
5. Torque all bus clamps to 38 lb-ft ± 2 lb-ft (52 N-m ± 3 N-m).
Description
Common DC
Bus Quantity Common AC
Bus Quantity
8-hole, straight busbar splice 4 6
Bus clamps ! 8 12
Flat washer 16 24
Nut/conical-spring washer 16 24
! For each busbar end with built-in clamps, decrease the required quantity by 2.
!
ATTENTION: Verify that the busbar splices are of the same
thickness as the busbars to be spliced.
For lineups containing common bus F-frame 2362 units, any
G-frame 2362 units, or M/N-code 2364F units, the bus splices
should be sized to match the overall bus rating of the lineup. See
Figure 1.15 for an example.
If: Then:
Either bus has a built-in
bus clamp 1. Insert the bus clamps, from the backside,
through the holes at the ends of the busses without
built-in bus clamps. See Figure 5.3(a).
2. Slide two busbar splices over the ends of the
bus clamps on the front-side of the bus.
Neither bus has a built-in
bus clamp 1. Position one busbar splice behind the bus as
shown in Figure 5.3(b).
2. Insert the bus clamps, from the backside,
through the busbar splice and bus.
3. Slide the second busbar splice over the ends of
the bus clamps.
