Ac Out Fuse Multiplus 2

When I connect a cable from the ac out of a multiplus 2 to a distribution box, do I also have to place a fuse directly after ac out to protect the cable to the distribution box or are the breakers in the distribution box sufficient?

The breakers to ac in and ac out in the distribution box are 25A and the cable is 4mm2.

yes, you should have a single fuse/breaker on the AC out of the multiplus, i.e.as a master switch, for both protection and isolation.

The Db can then have an assortment of other breaker ratings appropriate for their circuits.
