This guide for use by qualified installers only.
Distribution Panels
Some systems incorporate distribution panels both ahead of the inverter/
charger (the AC source panel) and between the inverter/charger and the
loads (the AC load panel). The AC source panel includes a main circuit
breaker, which serves as over-current protection for the panel. Additional
circuit breakers serve individual circuits, one of which serves the inverter/
charger.
AC Wiring
Definition AC wiring includes input wiring (all the wires and connectors
between the AC source and the inverter/charger input) and output wiring
(all the wires between the inverter/charger and the AC load panels, circuit
breakers, and loads).
Type The type of wiring required varies according to the electrical codes
or regulations applicable to your installation. For RV applications, this may
be solid wire in multi-conductor cables, but stranded wire is required if
single conductors are used. All wiring must be rated 90 °C or higher.
Size of AC Input Wiring Wire size must be coordinated with the
overcurrent protection provided ahead of the wire involved, in accordance
with the electrical codes or regulations applicable to your installation.
Therefore, the wiring used between the AC input circuit breaker and the
inverter/charger input must be sized to match the input breaker rating.
For dual input, the wire may be red or black; consult the documentation
provided with the AC source (utility or generator).
Size of AC Output Wiring Wire size must be coordinated with the
current the wiring will carry. This current may be determined by the 25 A
maximum inverter current, or by the bypass current, which is determined by
the overcurrent protection provided ahead of the Freedom SW 3000.
• If the input wiring is split-phase, the output wiring must be sized to
coordinate with the breakers used on the input. Refer to your
applicable installation codes.
