Hi chaps.
Something doesn’t seem quite right with my MEB, and I'd like to get an opinion more professional than mine about it. I’m pretty sure my earth is a TN-S system, although a couple of things puzzle me:
One, the main earth bond only seems to be in about 4mm2 wire. And it’s the old silver-coloured stuff, not copper. After having a dig in these forums, I think it should be at least 16mm2 to be safe.
Two, I was under the impression that a TN-S earth connected to the neutral conductor. The earth that’s on it now splits and connects to both the phase and neutral sleeves. Is this right?
There’s a picture below if any bits of that don’t make sense.
Cheers for your help,
P
