enphase CT-100-SPLIT ROW Installation Instruction page 2

To monitor consumption on Line 2:
•
Connect the white wire to the "I2•" terminal and the blue
-
wire to the "I2"terminal.
Clamp the CT on the main supply Line 2. When the Con-
-
sumption CT is on Line 2 conductor, the arrow must point
toward the load (away from the grid).
To monitor consumption on Line 3:
•
Connect the white wire to the "I3•" terminal and the blue
-
wire to the "I3" terminal.
Clamp the CT on the main supply Line 3. When the Con-
-
sumption CT is on Line 3 conductor, the arrow must point
toward the load (away from the grid).
Tighten all connections to 0.56 N m.
•
C ) Close and secure the terminal block door of the IQ Gateway.
D ) Turn on the PV system.
INSTALLATION TIPS
Installing multiple conductors in a single CT
If you need to install multiple conductors in a single CT, you must
ensure that the conductors terminate on the same line conductor,
so the voltage at the terminals of the two conductors will be 0 V
between them.

There are some challenges to this approach:
It is easy to make a wiring error.
-
The conductors must fit within the CT.
-
All of the conductors on Line 1 must be bundled and with the loads on the
-
Line 1 CT.
All of the conductors on Line 2 must be bundled and with the loads on the
-
Line 2 CT.
All of the conductors on Line 3 must be bundled and with the loads on the
-
Line 3 CT.
You may need to extend some of the circuits.
-
It is often possible to run all the conductors in a service panel through a single
set of Consumption CTs.
Installing parallel-connected CTs for 200 A services and in crowded service
panels
It may be difficult to install multiple conductors through a single CT when some
of the conductors enter from the bottom of the service panel and others enter
from the top. Also, some service panels have 200 A services that are provided
by a set of two 100 A conductors and parallel-connected 100 A circuit breakers.
In those scenarios, you can use a set of parallel-connected consumption CTs to
monitor the home's consumption. Do this by installing two Consumption CTs,
one on each line conductor and then parallel-connecting the output conductors
at the IQ Gateway CT wiring terminals or in a wire connector before landing in
the IQ Gateway terminals.
