Hi all,
Something that's been bugging me for a while but never got around to looking into. The earth from my cutout to the MET seems very small. I'd guess at 2.5mm - it's solid core, not stranded. I've attached a picture. Supply is TN-S fed by split con (confirmed when a contractor came to fit an isolator for me), which appears to be daisy chained from next door (it heads under the floor to the other side of the house which is where my neighbours are attached).
The contractor never mentioned the earth, and didn't seem to even know what TN-S was when I asked him (I had to rephrase it and ask him if the link between neutral and earth was present in the cutout). I didn't want to ask any more questions after this.
Therefore I have two questions:
1) Is the earth between the cutout and MET undersized? Fuse in cutout is 100Amp (confirmed by the contractor).
2) If is is undersized, who is responsible for replacing it? As you'd need to break the seals in order to change it, I'd guess the DNO are responsible.
Thanks in advance for any replies.
Jon
