INTRODUCTION
Metal
-
clad
switchgear
is
equipment
designed
for
the
pro
-
tection
,
instrumentation
and
control
of
various
types
of
electrical
apparatus
and
power
circuits
.
and
4
.
The
equipment
is
not
designed
for
exposure
to
dripping
liquids
as
this
condition
is
not
a
usual
ANSI
service
condition
.
Dripping
liquids
can
destroy
the
integrity
of
the
insulation
system
and
must
be
avoided
.
The
switchgear
consists
of
one
or
more
vertical
sections
which
are
mounted
side
by
side
and
connected
mechanically
and
electrically
to
form
a
complete
switching
equipment
.
Typical
pieces
of
equipment
are
shown
in
Figs
.

,
2
and

.

EQUIP
-
MENT
MAXIMUM
The
circuit
breakers
are
easily
removable
to
provide
maximum
accessibility
for
maintenance
with
minimum
interruption
of
services
.
The
switchgear
is
designed
to
pro
-
vide
a
high
degree
of
safety
to
the
operator
.
All
equipment
is
enclosed
in
grounded
metal
compartments
.
The
equipment
is
available
in
the
ratings
listed
in
the
following
table
.
The
ratings
of
the
equipment
and
devices
are
based
on
usual
service
conditions
as
covered
in
ANSI
stan
-
dards
.
Operation
at
currents
above
the
equipment
rating
will
result
in
temperature
rises
in
excess
of
these
standards
,
and
is
not
recommended
.
For
outdoor
installation
the
same
basic
equipment
is
built
into
a
weatherproof

A
SAFETY
Each
user
is
responsible
for
communicating
all
safety
in
-
structions
and
practices
to
personnel
associated
with
this
equipment
.
The
following
practices
should
be
included
in
a
user
’
s
safety
program
.
These
do
not
supplant
the
user
’
s
responsi
-
bility
for
devising
a
complete
safety
program
.
They
are
rather
suggestions
concerning
some
aspects
of
personnel
safety
related
to
circuit
breakers
and
metalclad
switchgear
equipment
.
General
Electric
assumes
no
responsibility
for
user
practices
which
deviate
from
these
recommendations
.
Although
the
interlock
linkage
has
been
designed
to
be
rugged
,
inadvertent
bending
of
the
spring
discharge
and
/
or
negative
interlock
actuating
linkages
during
breaker
stor
-
age
,
lift
truck
or
stack
insertion
operations
could
negate
their
proper
functioning
and
therefore
create
a
safety
risk
.
This
type
of
handling
damage
must
be
avoided
by
any
user
.
All
servicing
of
switchgear
must
be
performed
only
by
trained
personnel
,
with
BOTH
THE
PRIMARY
AND
CONTROL
POWER
CIRCUITS
DE
-
ENERGIZED
.
GENERAL
1
.
The
term
“
metalclad
switchgear
”
includes
circuit
breakers
,
associated
interrupting
,
switching
control
,
metering
and
protective
devices
,
together
with
their
supporting
metal
structures
,
enclosures
,
electrical
connections
and
accessories
.
2
.
All
personnel
associated
with
installation
,
operation
and
maintenance
of
metalclad
switchgear
should
be
thoroughly
instructed
and
supervised
regarding
power
equipment
in
general
as
well
as
the
particular
model
of
equipment
with
which
they
are
working
.
Instruction
books
should
be
closely
studied
and
followed
.
These
instructions
do
not
purport
to
cover
al
!
details
or
variations
in
equipment
nor
to
provide
for
every
possible
contingency
to
be
met
in
connection
with
installation
,
operation
or
maintenance
.
Should
further
information
be
desired
or
should
particular
problems
arise
which
are
not
covered
sufficiently
for
the
purchaser
'
s
purposes
,
the
matter
should
be
referred
to
the
General
Electric
Company
.
To
the
extent
required
the
products
described
herein
meet
applicable
A
NS
I
,
IEEE
and
NEMA
stand
-
ards
;
but
no
such
assurance
is
given
with
respect
to
local
codes
and
ordinances
because
they
vary
greatly

Particular
care
must

Information
on
construction
of
such

is
provided

In
this dis

If
there
is
any
evidence
of
or
suspected
deterioration
of
breaker
dielectric
capability
,
adjacent
areas
should be
promptly
cleared
of
personnel
.
The breaker should

Maintenance
programs
must
be well
planned
and
carried
out
in
a
manner
consistent with
both
