RE-INSTALLATION OF SWITCH BARRIERS IN TYPE PSE
DEAD-FRONT PAD-MOUNTED SWITCHGEAR

7. Note the position and location of the switch barriers in
the slots on the switch frame and along the fiberglass
barrier-support angle. See Figure 4. At both ends of
the slotted barrier-support angle, loosen (to the extent
possible, but do not remove) the hardware (using the
1/2" and 9/16" ratchet or box
wrenches) that secures
the fiberglass angle to its barrier-support bracket. See
Figure 5.
DO NOT
loosen the hardware that secures the
bracket to the stud on the enclosure side wall.
8. With the switch barriers taped in position and the barrier-
guide support angle adequately loosened, remove the
displaced barrier. If still necessary to gain additional
flexibility, the hardware may be removed and retained.
Figure 6. Insert the two tabs on the switch barrier into corresponding slots in the switch frame and insert the slot in the switch barrier into the
slot on the fiberglass barrier support angle.
9. Re-install the barrier that was displaced and, if desired,
apply tape (as was done for the other barriers) to secure
it in position, making certain to install the barrier with the
tab on the top-front edge of the barrier into the top slot
on the switch frame; the tab on the bottom-front edge
of the barrier into the appropriate slot on the bottom
angle of the switch frame; and the slot on the top-rear
edge of the barrier into the slot on the fiberglass barrier-
support angle. Refer to an adjacent switch barrier that
is already installed to establish appropriate installation
and positioning of the switch barrier into the switch
frame and barrier-support angle. See Figure 6.
Figure 4. Note how the tab, corner and edge of each
switch barrier nests in the appropriate slots in the switch
frame and fiberglass barrier support angle.
Figure 5. Loosen the hardware that secures the
fiberglass angle to the barrier support bracket at each
end.
