Method B: End-feeding the branch circuit
A For QD Cable SKUs QD-12-10-150 and QD-12-20-135,
the voltage rise in the QD Cable is <1% and hence End
Feeding or Center feeding methodology can be used
for the three phase AC Supply.
NOTE: QD Cable SKUS QD-12-10-150 and QD-12-10-135 does not include separate center tapping connector within the cable. Hence it is
recommended to use off-the shelf junction box for center feeding the three phase AC supply.
Step 06: Terminate the unused end of the cable
Install a terminator QD-TERM-10 on the unused end of the
QD Cable that is not terminated with a Field Wireable QD
Connector.
A. Remove 20 mm (0.8 inches) of the cable sheath from
the conductors.
B. Slide the hex nut onto the cable. There is a grommet
inside of the hex nut that should remain in place.
C. Insert the cable into the terminator body so that each
of the four wires land on opposite sides of the internal
separators.
Turn only the hex nut to prevent conductors from twisting out of the
separator.

B Use the Enphase 3 Phase Field Wireable Connectors
(QD-CONN-10M and QD-CONN-10F) for end feeding
the AC supply to IQ8D Microinverter branch circuits.
OR installers can use off-the shelf junction boxes
for end feeding or center feeding the three phase AC
supply to IQ8D Microinverter branch circuit.
183 to 229 VAC
D. To attach the cap:
• Bend the wires down into the recesses of the
terminator body and trim as needed. Place the cap
over the terminator body.
• Insert a screwdriver into the slot on the terminator
cap to hold it in place.
• Rotate the hex nut with your hand or a wrench until
the latching mechanism meets the base.
• Do not over torque.
E Attach the terminated cable end to the PV racking
with a cable clip or tie wrap so that the cable and
terminator do not touch the roof.
The terminator cannot be reused. If you unscrew
the nut, you must discard the terminator.
