Hi
I have a modern (steel) dual RCD board. My solar inverter is on a dedicated circuit with a B20 MCB on one of the two RCD segments.
Am I right in thinking this is bad practice as it means the RCD tripping won't prevent current flow to the circuits fed by that RCD for the three second permitted shutdown time?
How important is it to resolve and what's the simplest way? I could move the solar circuit to before the first RCD but then it won't be on the busbar segments so I'll need some chunky tails to join to the first RCD. Do you use 25mm or is there something specific?
I have a third neutral bar in the CU.
Thanks
