INTRODUCTION
I
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.
