From what I've gathered since I posted the query, the supply from the pv side is connected to an mcb input terminal. This allows isolation but it is the only time an input supply is ever connected to the load terminal of an mcb! I worry as to what a spark who isnt aware of this might do while testing or working on the cu of such an installation. Anyone else out there to reply to this? This mcb is really a separator to separate the two sources, the PV and the Grid.
