INTRODUCTION
equipment
is
built
into
a
weatherproof
housing
as
in
Figs
.

.
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
.
Metal

switchgear
is
equipment
designed
for
the
pro
-
tection
,
instrumentation
and
control
of
various
types
of
electrical
apparatus
and
power
circuits
.
\
The
switchgear
consists
of
one
or
more
vertical
sections
/
which
are
mounted
side
by
side
and
connected
mechanically
and
electrically
together
to
form
a
complete
switching
equipment
.

If
dampness
or
condensation
may
be
encountered
in
the
storage
location
,
(
can
occur
with
rapid
temperature
changes
)
heaters
should
be
placed
inside
the
equipment
to
prevent
moisture
damage
.
Approximately
300
watts
of
heat
per
vertical
stack
will
be
required
.
The
suggested
arrangement
is
one

watt
heat
element
in
each
breaker
and
primary
cable
compartment
.
Remove
all
cartons

other
miscellaneous
material
packed
inside
units
before
energizing
any
heaters
.
If
the
equipment
has
been
subjected
to
moisture
it
should
be
carefully
dried
out
using
forced
warm
air
and
then
tested
with
a
1000
or
2500
volt
megger
