Connect the hot conductors and neutral conductor in a general AC cable from the AC junction box to the designated terminal in the distribution panel.
Then, connect conductors in transition cables to the AC junction box as shown above.

AC output three phase 208VAC - split type

To form balanced three phases, it is recommended to use 3-array equal to the number of AC modules in each array . Below is other example for AC output cables connection of three phase 208VAC.
