DANGER
DO NOT USE GREASE OF ANY KIND. GREASING OF THE FINGER CLUSTERS
OR PRIMARY CONDUCTORS WILL VOID THE WARRANTY AND OVER TIME
CAN CAUSE A BUILDUP OF CONTAMINANTS THAT CAUSE TRACKING
OVER THE SURFACE OF THE INSULATION OR WITHIN THE CELL BOTTLES.
FAILURE TO HEAD THIS WARNING CAN CAUSE DEATH, SERIOUS
PERSONNEL INJURY, AND / OR PROPERTY DAMAGE.
•
Orient the finger cluster with the smaller diameter of the fingers
towards the primary conductor.
•
Place the large retaining washer inside the finger cluster cavity.
•
Insert the longer 5/16” hex bolt through the finger cluster and
retaining washer. (Figure 4.11)
•
Push the finger cluster against the primary conductor stem.
(Figure 4.12)
4.7.2 Changing 2000A Finger Clusters to 1200A
The 2000A Universal G&T DHP finger cluster is easily changed by
removing the 5/16” hex head bolt, lock washer, and large retaining
washer. (Figure 4.7)
Grasp the 2000A Universal G&T finger cluster firmly and pull to
remove from the primary conductor. (Figure 4.14)

•
Thread the hex bolt into the primary conductor stem and tighten
to pull the finger cluster onto the primary stem. Once the finger
cluster is drawn onto the primary conductor stem, but not fully
seated, remove the long 5/16” hex bolt.
•
Thread the shorter hex head bolt and lock washer into the primary
conductor stem and tighten until the flat washer is collapsed. Do
not over tighten. (Figure 4.13)
•
Repeat the process until all finger clusters are changed to the
proper rating.
Remove the large retaining washer if the finger cluster is to be
replaced or if mounting a 1200A DHP finger cluster. Repeat the
process for all finger clusters.
Select a 1200A DHP finger cluster.
Apply a thin film of wax (Johnson’s Paste Wax-available from many
retailers-used for furniture) to the outer surface of the primary
conductors (Figure 4.9) and to the inside contact surfaces of the
fingers (Figure 4.15). The finger cluster should be re-waxed each
time a finger cluster is changed or approximately every 50 insertions
and removals. The wax will not form a build-up and will not attract
dirt and contaminants if properly applied.
