Looking for a bit of advice here. I am replacing the CU which is currently in a shower room. Now, don't gasp too hard, it's not as bad as it sounds. The shower is in a totally enclosed cubicle with a good extractor, and the room never gets steamy or has condensation. The existing CU is in a...

Hi all.
As I understand it, exported earth is only an issue for PME situations? Therefore, when a domestic installation is a TT and power is to be brought out to a remote outbuilding, is there a requirement to fit a second earth electrode and if so, should this be independent of the house TT...
