See im baffled by the ze yes water and gas bond disconected Defo tt even got a note on the cut out dont supply PME ,16mm to 3/8 spike at source then a 16mm 3 core swa via a switch fuse to the DB, i never disconected outgoing neutrals on my rcd test at the unit its self , the testers only 3 months old but im hearing there are issues with the earth pins inside it's a robin MFT going to borrow a mates and see if thats the issue, but i just can't understand one working and the other not. Looking in the board im not 100% its not been adapted from a old 100amp 30/ma split load style and the busbars etc might not be right but it all seemed to be conected fine to me. A longer look maybe required apon my return i think.
An Ra of 0.70 ohms on a 3/8'' twig?? Not even in your wildest dreams!! lol!!!, Even the dammed cable is bigger than the spike it's attached too....
