INTRODUCTION

CAUTION:
The equipment covered by this publication
must be selected for a specific application and it must
be installed, operated, and maintained by qualified
persons who are thoroughly trained and who understand
any hazards that may be involved. This publication is
written only
for
such qualified persons and is not
intended to be a substitute for adequate training and
experience
in
safety procedures for this type
of
equipment.
These instructions are for field assembly (erection)
and installation of manually operated S&C Grounding
Switches, rated
70,000
amperes momentary, when
furnished as
original
equipment for Mark
V
Circuit-
Switchers rated
230
kv. Supplemental dimensional
details for the grounding-switch installation are
included on the erection drawing furnished for the
applicable Circuit-Switcher.
(NOTE:
If
a
grounding switch
is
to be added to an
existing
Circuit-Switcher installation, the components
should be assembled in accordance with the special
drawings provided.)
The inclusion of
a
grounding switch rated
70,000
amperes momentary is designated by the addi-
tion of the suffix “-G3” to the Circuit-Switcher catalog
number.
Install the grounding switch only after the Circuit-
Switcher and its power train have been completely
installed and adjusted.
Grounding-switch components and subassemblies are
packaged separately for shipment. They are tagged and
keyed to the bill
of
material on the erection drawing
to facilitate field erection.
Study the erection drawing carefully to determine the
overall configuration and the arrangement
of
compo-
nents. Then proceed
as
directed in the step-by-step
instructions which follow.
