Is it a tt supply

[Ajf100q]

Might be a silly question, but can a tt supply come into a property via underground .
This property in question, has no overhead cables supplying it but looks like it might have an earth electrode somewhere.
Thanks.

Impossible to say some dwellings have an electrode under the floorboards.

Plenty will have it under six inches of concrete in the 'extension'.

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.

Thanks, yes they are getting a survey from Dno to see what can be done.

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)


"The new wording within Regulation 411.4.2 is the final paragraph, where it introduces a recommendation that an additional connection to Earth by means of an earth electrode to the main earthing terminal. ." Taking for Napit site
i did notice the Sticker 25/08/23 and i wonder how old the house is

(hope this is within this site rules)

New build? Youve got a pretty broad definition of new!

Regardless TT systems can be installed for new builds

I based it on the person location found from their profile which I think I got told off for

Yes my property has a undergroung cable from a overhead pole in the road.

Underground or overground supply, there may well be a TNC-S earthing terminal provided in the service head, but the DNO might not give permission to use it, if the installation doesn't meet the bonding requirements for TNC-S. Not an uncommon occurrence for me, with some of the ramshackle part steel buildings I've been asked to install into.
