POWER
LEADER
Communication
Network
The
POWER
LEADER
Communication
Network
(
commnet
)
transmits
data
and
instructions
between
the
trip
unit
and
an
external
intelligent
device
.
The
external
device
may
be
the
POWER
LEADER
system
,
the
Epic
system
,
or
a
POWER
LEADER
Monitor
.
Devices
on
commnet
may
be
up
to
1000
feet
apart
without
signal
repeaters
,
subject
to
certain
con
-
straints
.
Commnet
connections
are
made
directly
to
wiring
terminations
on
breaker
frames
.
All
commnet
con
-
nections
to
the
trip
units
are
made
through
the
36
-
pin
plug
on
the
trip
unit
,
which
mates
with
a
recep
-
tacle
on
the
breaker
frame
.
These
additional
connec
-
tions
are
made
to
the
equipment
