1/0 AWG or 2/0 AWG
Thanks for any input on this :-)
The fuse or circuit breaker on the output of the battery bank is sized to protect the cables. The breaker is intended to trip before damaging current is exceeded.
The first step in the design is to determine the system load. In this case power flows both ways. The larger of the two is used.
The second step is to choose the wire size needed to support the load.
The third step is to choose a circuit protector for that wire size.
The fuse or breakers then reflect the wire size to use.
What is the size of the output breakers? Are there more than one and if so what sizes are they? If complicated, please lay out the output configuration.
