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)
Figure 4.14. 2000A Universal G&T Finger Cluster Removal
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.
