GENERAL
INFORMATION
Whenever
the
ground
fault
trip
element
is
fur
-
nished
for
breakers
applied
on
4
-
wire
systems
,
note
that
,
an
associated
neutral
sensor
(
CT
)
is
re
-
quired
for
separate
mounting
in
the
equipment
.
Make
sure
that
retrofitted
breakers
are
applied
within
their
short
circuit
ratings
.
For
example
,
when
the
breaker
’
s
trip
elements
are
to
be
changed
from
long
-
time
instantaneous
to
long
-
time
,
short
-
time
,
the
short
-
time
rating
would
gov
-
ern
the
application
.
As
a
service
-
related
consideration
,
the
installation
of
the
MicroVersaTrip
®
Plus
or
PM
kit
provides
an
excellent
opportunity
to
perform
normal
mainte
-
nance
on
the
breaker
,
particularly
while
the
front
and
back
frames
are
separated
.
Such
procedures
are
described
in
installation
and
maintenance
manuals
normally
supplied
with
breakers
and
equipment
.
Conversion
kit
installation
is
straightforward
.
However
,
careful
workmanship
and
attention
to
these
instructions
should
be
maintained
.
Famil
-
iarity
with
the
breaker
will
prove
helpful
.
The
general
approach
is
to
first
strip
the
breaker
of
its
existing
trip
devices
and
then
install
the
program
-
mable
trip
unit
MicroVersaTrip
®
Plus
or
PM
components
.
Following
this
,
the
converted
breaker
is
performance
-
tested
prior
to
being
restored
to
service
.
The
majority
of
breaker
kit
installations
do
not
re
-
quire
any
customized
assembly
work
.
However
,
some
conversions
may
involve
unusual
mounting
circumstances
or
accessory
'
combinations
which
necessitate
minor
modification
and
or
relocation
of
a
component
(
s
)
.
In
most
instances
,
this
supple
-
mentary
work
can
be
done
on
site
.
Preparatory
to
the
conversion
,
the
installer
should
verify
that
the
correct
kit
,
current
sensors
and
programmable
trip
unit
have
been
furnished
.
