Have a single 230v 50hz victron Quattro 10,000VA. AC output 1 is supplying a small AC Panel. The AC Panel has a 63A inlet breaker and RCD, and dedicated breakers for each consumer. There are no other supplies into this AC Panel.
The Quattro manual advises the following "An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be included in series with output L1, and cable cross-section must be sized accordingly."
In the technical specifications part of the same manual, it advises that there is automatic short circuit, and overload protection. My question is, if these safety features are built in, why must there be a breaker on the AC output side of this inverter??.
