Am i right in saying this is a TNC-S earthing arrangement?
The supply cable (which looks perished any advice on this welcome) comes from the wall in between the two houses (its a semi-detached). And no sign of it outside wall. So must be fed from underground. But there is a separate stranded cable that has earth sleeving on it and goes in to the MET which then also has the link wire to the Neutral terminal. Obviously I cant see any more of it it just goes into the wall. But it looks crap and undersized!
I am still training as an electrical engineer and Im interested to learn the donestic side (earthing systems, inspection and testing etc.) but it is my house. Probably going to ring YEB replace supply cable..
Thanks in advance for any comments!
