Size of 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
by the manufacturer of the power source (that is, the generator).
Size of Output
Wiring
Wire size must be coordinated with the current the wiring will carry. This 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 RS3000
•
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. For a 50 A input breaker, the output wiring is usually No. 8 AWG.
•
If the input wiring is dual-input and the output wiring is single-input, the
following rules apply: If the input breaker on L1 is greater than 25 A, the wire
size must be coordinated for that amperage. If the input breaker on L1 is less
than 25 A, the wire size must be coordinated for 25 A. The wire size must not
be sized for anything lower than 25 A.
•
If both the input and the output wiring are dual-input, the output wiring for
each line (L1 and L2) must be calculated separately, following these rules: If
the input breaker on the specific line is greater than 25 A, the wire size for that
line and its neutral must be coordinated for that amperage. If the input breaker
on the specific line is less than 25 A, the wire size for that line and its neutral
must be coordinated for 25 A. The wire size must not be sized for anything
lower than 25 A.
Size of Wiring
Downstream of the
AC Output Breaker
The wiring used between the AC output breaker and your loads must be sized to
match the output breaker.
