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
.
SECTION

PRIOR TO
INSTALLATION
•
Turn
off
and lock
out
the
power
source
feed
-
ing
the
breaker
prior
to
attempting
any
installation
,
maintenance
,
or
modification
.
Follow
all
lockout and
tagging
rules
of
the
National
Electrical
Code
and
all
other
appli
-
cable
codes
.
•
Do
not
work
on
a
closed
breaker
or
a
breaker
with
the
closing
springs
charged
.
Trip
OPEN
the
breaker
and
be
sure
the stored
energy
springs
are
discharged
avoiding
the
possibility
that
the
breakers
may
trip
OPEN
or
the
charg
-
ing springs
discharge
,
causing
injuries
.
•
For
both
stationary
and draw
out
breakers
,
trip
OPEN
,
then
remove
the
breaker
to
a
well
lighted
work
area
before
beginning
work
.
•
Do
not
perform
any
maintenance
including
breaker
charging
,
closing
,
tripping
,
or
any
other
function
which could
cause
significant
movement
of
the
breaker while
it
is
on
the
draw
out
extension
rails
.
•
Do
not
leave
the breaker
in
an
intermediate
position
in
the
switchgear
compartment
.
Al
-
ways
leave
it
in
the
CONNECTED
,
TEST
,
or
DISCONNECTED
position
.
Failure
to
do
so
could
lead
to
improper
positioning
of
the
breaker
and
flashback
.
Before
starting
any
work
turn
off
and lock
out
all
power
sources
leading
to
the breaker
(
primary
and
secondary
)
.
Remove
the breaker
to
a
clean
,
well
lighted
work
area
.
