Thought I was onto a real winner today when checking the gas bond to find a nice bonding conductor run directly to a local earth rod:
The main house is currently TT with a rod on the opposite side of the house, so maybe they thought the foundations counted as a massive MET
Was all set to run cabling round the house, but as it happens, further testing between the MET and this showed very low resistance (boiler cpc was my first guess), and when I delved into the CU there was a 10mm bonding conductor which goes maybe to the boiler in the attic, and gives a reading of 0.04 back to this pipe.
Means their current earth is effectively the gas pipe rather than either rod though, since Zs on my new lights outside is 2Ohmish, while Ze was 193...
DNO visit in a week or so hopefully will upgrade to PME.
Any reason electrically to remove this connector? Might stop the next guy thinking the same, though I will put a sticker inside the box or at the CU to clarify I think.
