The following table shows the information of cable size and torque
values that should be used in the position (1) pole / position (2) pole /
position (3) pole in the AC terminal when a 208V grid system is applied
with the PV inverter.

IMPORTANT
The selection for the AC cable size and required torque values for
the Position 1 / Position 2 / Position 3 is referred to the table 310.16
in the National Electrical Code (NEC).
E)
Connect the AC cables with PV inverter by inserting them through the
conduits into wiring box as figure 7.2.4 shown:
Figure 7.2.4: Insert the AC cables through conduit
F)
For the AC cables, the terminal connectors are recommended to be
used with AC cables in order to ensure the effective electric conduction
between AC cables and AC terminals as shown in figure 7.2.5.
