Unit
Before
installing
the
breakers
,
verify
that
the
rod
linkage
is
centered
and
free
to
move
in
either
direc
-
tion
.
After
installing
the breakers
in
the
compartments
,
charge
the
closing
springs
on
both
breakers
.
Close
one
of
the
breakers
,
then
attempt
to
close
the other
.
The
second
breaker should
immediately
trip
.
Repeat
the
test
with the
breakers
in
the
opposite
order
.
If
the
sec
-
ond
breaker
does
not
trip
in
either
case
,
check
that
the
rod
connecting
the
breakers
is
free
to
move
i
n
both
directions
when the breakers
are
sequenced
from
OFF
to
ON
.
If
the rod
is
adjusted
too
short
,
one
of
the
breakers
will
nuisance
trip
even
when
the
other
breaker
is
off
.
If
the
rod
is
adjusted
too
long
,
the
inter
-
lock
mechanism will
not
operate
properly
.
A
good
length
is
one
that
eliminates
the
slack
between
the
compartment
linkages
