Connect 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.

Connect the general AC cables in the following order:

AC output single phase 240VAC

There is a sample for AC output cables connection of single phase 240VAC below.
