( Porcelain inter-unit bus supports )
Step – 4, Remove glastic shipping supports
Unbolt and remove the glastic shipping supports taking care to ensure that splice plates
and spacers provided in the bus joint do not fall off. Loosely refasten bus hardware to
hold the splice plates and spacers in place. Discard the shipping supports. The red
insulating boots will have to be removed to access the bolts for the shipping supports.
The boots are held together using plastic re-useable pull-apart fasteners.
Step –5a, Remove inter-unit bus supports ( Go directly to step 5b if polyester glass bus
supports are provided)
a)
Apply strong adhesive tape so as to keep the two glastic supports together
temporarily. The tape may be applied in 4 places – above, below and between the
porcelain bus supports. See Fig A(1)-5 and Fig A(1)-6. In Fig A(1)-6, the bus
support is shown outside the switchgear to get good picture clarity. It is not
required to remove the bus supports out of the switchgear.
b)
Remove the ¼ - 20 fasteners used to mount the bus support to the side sheet.
There should be 4 ( 2 for poly glass) on the top and 4 ( 2 for poly glass ) at the
bottom. The hex nut should be towards the outside on the left hand side of the
side sheet.
c)
Gently remove the bus support assembly away from the side sheet and into the
bus compartment. Let it rest temporarily in a vertical position inside the bus
compartment.
