Center Tapping Adapter Cable; Figure 12: Voltage Rise For Qd-12-42-63 With End Feeding Of Ac Branch Circuit; Figure 13: Voltage Rise For Qd-12-42-63 With Center Feeding Of Ac Branch Circuit; Figure 14: Center Tapping Adapter Cable - enphase IQ8D-72-E-US Design Manual

Following Figure 12 and Figure 13 shows Voltage Rise for
last micro when AC branch circuit connection is done with
end feeding and center feeding respectively with Q-12-42-
63 landscape ballast cable.

Center Tapping Adapter Cable

The Center Tapping Adapter Cable with 300 mm (11.8
inches) length has 4 pole Link connector on one side which
should be connected to center tap connector in QD Cable
and 3 phase field wireables on other side which should be
used to make connections with extension cable to PV
