Just out of interest; the regs state do they not that the designer/installer (that's us) is liable for the correct operation of the kit... Zappi or matt:e or whomever are presumably not liable if their kit fails and kills someone in the case of an open neutral or similar? It's us who are liable. (So I was told by NAPIT...). So better to stick with earth rods and RCDs as known (and testable) technology, even if it's a pain to dig an earth rod hole? Just wondering what you old hands think? :)
