Default Continuity between neutral and earth

I have broken into a ring main to extend it to another room. Essentially cutting the return from one socket and then connecting each side of the extended ring to one of the cut ends.

I test the extended ring and it was sound (ie only continuity between the corresponding pairs of wire). I have just connected it to the main ring and did a quick continuity check. Live is ok but it seems that neutral (blue) and earth now have continuity. Given I tested the extended ring it would appear that the original ring suffered this problem. However if this was the case wouldn't the RCd at the MCU have tripped before.


ISTM that a person who does not know that neutral and earth MUST be connected together in at least one place is a person who is not qualified to do such work and the resulting installation is at risk of being in breach of the Building Regulations.
