Working on a old property in a slightly remote area installing a new circuit.
When I looked at the earthing it looked like a tns but I investigated and found a old 2.5mm running towards the rod.
My problem is I am getting a ze reading of 0.25 ohms.
Ino we had a really heavy down poor the day before but to be that low?
I am wait for the dno to confirm the earthing but they ain't rushing.
Any thoughts
I know a good reading for tt is 200 ohms or lower. This is the first one I have worked on
