Exporting TN-C-S earth in TN-S

Former Community Member
Former Community Member
I know this sounds weird, but let me explain before.


I have two dwellings both connected to one substation. One classified TN-C-S (dwelling A) and the other TN-S (dwelling B).


I have to run a new line for providing electricity inside the new plant room that will be built inside the dwelling B. The new line will be taken from a DB installed inside the dwelling A.


The reason because I need to do in this way, it is because of in the dwelling B I have no in enough power and I'm not allowed to run a new line from the substation.


My question is: if I run a new cable form the dwelling A to dwelling B, should I also connect the earth system of the dwelling A to the plant room in the dwelling B? I have to suppose yes. Obviously, I have to keep separate the two earth system, have not I?

    Don't fret Graham it's fine, I have been criticsed many times online for my way of trying to guide people to enlightnment rather than tell them, and you certainly didn't do that!

    My skin is thick enough, you can apologise in person in July if you like! ;)

    However, absolutely NO bad feelings I promise.
