New EICR - "No earth bond to some socket boxes: C2"?

Former Community Member
Former Community Member
I have a new EICR which has the observation "No earth bond to some socket boxes: C2".


I have checked continuity between all faceplate mounting screws and the earth of the socket. They are all connected, i.e. the back box is at least earthed by the screw if not with a tail internally (I have not removed the front plates of any sockets). The earth of each socket is connected to the ring.


While it is best practice, is it a requirement of the regulations that a tail is connected internally?


many thanks

    Also consider the failure mode of an slightly undersized c.p.c. - its only going to get a bit warmer that it should (e.g. above the typically 160 degree limit) - so it's not going to vaporise the copper c.p.c. just risk melting some insulation - at worst case creating some additional L-PE faults within the T&E cable (probably at bends) - which again should be cleared by the repaired fuse blowing again (probably with further damage to the cable) - all very inconvenient certainly, costly even and certainly well below the standard set by the regs, but the risk to the safety of users of the installation isn't that great I'd suggest.
