Surge protection

I have no spare ways in my CU and want to fit a surge protection device. I guess that something like the Hager VA4T2SDSPD or Wylex REC2SPD would do the needful, but would this replace the main isolating switch or would it be added in parallel like a workshop CU? Or can it be run with a smaller cable, say 10mm2?

The use case is a house packed with electronics including a Loxone smart home system.

Thanks

  • single module RCBO with neutral disconnect, which I think is unique?

    Not unique at all - most of the international suppliers make them as N switching seems to be the norm in France ... they just don't bother marketing them here much. A few smaller companies (Garo comes to mind for one) have had N switching RCBOs on the UK market for quite a few years now.
