Replacement of connectors for solar high current ring main unit

Ring Main Unit (RMU)

Ring Main Unit (RMU) is a switchgear device used in secondary distribution systems, i.e., between the distribution substation and the end consumer to ensure continuous power supply and isolate the faulty section from the network. The main purpose of using a ring main unit is to provide an uninterrupted power supply to consumers even in fault conditions.

New Solar PV System

My consumer unit has a split bus. It is wired so the downstairs ring shares a bus with the upstairs lighting, and vice versa. This is so a trip caused by (eg) a faulty hairdryer won''t extinguish the lights in the same room where the fault happened. But, similarly to my question about the MCB, whichever bus you connected the inverter to, current
