Not yet, just seen some pictures.Possibly have you done a test to it?
I can't be sure, but that looks smaller than 16mm, maybe as small as 6mm? That would be consistent with it being a TT rod and not a supply TN earth.The earth cable on the right of met, just dissappears into the ground with the service cable apparently.
I can't seem to view the pic but if it is 6.0 this doesn't mean too much.I can't be sure, but that looks smaller than 16mm, maybe as small as 6mm? That would be consistent with it being a TT rod and not a supply TN earth.
You might find Zs is very low like TN if bonded services are large and/or linked to TN supplies in other houses, but if you can identify the conductor that is the means of earthing then a Ze test would confirm it is likely TT if somewhere in the, say 5 ohm to 200 ohm region.
Can you see if it has an incomer delay RCD, or if all boards are all RCD/RCBO?
Not that I can see.There is nothing from the service head?
Indeed, not a reliable indicator!I can't seem to view the pic but if it is 6.0 this doesn't mean too much.
Plenty will have it under six inches of concrete in the 'extension'.Impossible to say some dwellings have an electrode under the floorboards.
Thanks, yes they are getting a survey from Dno to see what can be done.Yes it is possible to have an underground TT supply. Any supply can be made TT if required.
However it more than likely has an earth connection available that nobody has yet taken advantage of.
Contact the DNO to check the availability of an earth.
Don't link-build like that mate just stick the url in your signature on the forum and post normally please.I would be a bit shocked if it is a TT system in.
looking at the area it looks like NEW BUILDS there (within a few years)

I based it on the person location found from their profile which I think I got told off forNew build? Youve got a pretty broad definition of new!
Regardless TT systems can be installed for new builds
