Wiring Power
Wiring the
Entelica Meter
i
s very simple.
The electrical wires that are provided
with the
Entelica Meter
are labeled: NEUTRAL (White), PHASE
-
1 (Black),
PHASE
-
2 (Red) and PHASE
-
3 (Blu
e
). Besides the NEUTRAL wire
, which
is
connected to the Neutral bar
, each of the “PHASE” wires must be connected to
separate 10A
-
20A circuit breakers
(
see
Figure
3
and
Figure
4
)
.
2.2
Wiring CTs
To measure energy consumed per circuit, current transformers (CTs) will be
used.
The
Entelica Meter
comes with 42 terminals for CT
s connection, of which,
s
ix (6) terminals
are located on top of the enclosure and eighteen (18) on the
side
(
see
Figure
2
)
.
The top terminals are to be used
for measuring energy of
each PHASE; and the terminals on the side are for
measuring energy of each
circuit.
Each CT will use 2 terminals; therefore 21 CTs can be connected to this
product.

42 terminals for CTs connection
To connect a CT to
a
terminal o
f the Energy
Meter
, insert the wires
of the CT to
the “
+
”
and
“
-
“terminal
s
while depressing
the yellow tab of the terminal. Make
sure that the insulation is stripped from the wire and that the wire is inserted as
far in as possible. Next, i
nsert the
CT
to the desired
power
line
that is connected
to the
circuit breaker to measure energy for that
particular feed.
