Done a board change at domestic property ti an rcbo and spd board, previously had old rewireable fuse board, and done all my ir tests and so on and everything seemed good, lo and behold I get a phone call that the downstairs sockets have tripped, I told them to remove all loads and the circuit still tripped overnight.
I then went back to job and found a loose neutral in one of the sockets which I then connected and everything was back up and running, keep in mind that security system is on this circuit via a unswitched spur.
I then decided to redo an ir test only to find that there was a complete dead short between all conductors even after removing all loads and fuse from the spur and also removing the wires from the rcbo and earth bar.
Any help would be greatly appreciated.
