Installation
Connecting Conductors
Step 27
DANGER
Conductors must be de-energized and
grounded in accordance with standard system
operating practice. Failure to do so can
result in serious injury or death.
Attach the high-voltage conductors to the termi-
nal pads using exible-conductor connections.
Observe the terminal-pad loading limits speci-
ed on the catalog drawing.
Use the following procedure for attachment:
(a) Thoroughly wire-brush the current-
transfer surfaces of each connector and
immediately apply a liberal coating
of Penetrox® A (available from Burndy
Corporation) or other suitable aluminum-
connector compound to the brushed
surfaces.
(b) Wire-brush each circuit-switcher terminal
pad and apply a coating of Penetrox A,
then bolt the connectors to the terminal
pads.
(c) Prepare the conductors using estab-
lished procedures and clamp them in
their respective connectors.
Remove the Interrupter Containers
Step 28
Remove the container from each interrupter
as follows.
(a) Remove and discard the ⅜–16-inch zinc-
plated serrated hex nuts that run the
length of the container.
(b) Remove and discard the two ⅜–16×
1-inch and two ⅜–16×⅞-inch zinc-plated
hex-head cap screws and at washers
that attach the two container-halves
to the coupling end casting of the
interrupter.

closing springs and the open disconnect.
