no earth

[sima24]

Hi, been to look at a rewire today and no earth connection at all. Tried to contact supply company to enquire weather the property is connected to a pme system but no joy after holding most the afternoon. I presume supply company doesnt have to supply an earth but just wondering if they would upgrade to pme or not? Or possibly it is a pme system but earth has been disconnected at some point (no sign of pme label tho) any views appreciated. Thanks.

I don't know what type of property or building, but can you not make it a TT system with an inspection pit and earth rod.

Yes thats the plan if their is no earth connection. Just seems strange for the location and age of the property that their appears to be no earth or rod currently installed.

Test it as 2 wire test. Or look in street and see what they have done to cables, are they still overhead, but not earthed down the poles every so often. Go knock on a few doors in the street, and explain what your trying to establish.

Its one of the biggest pitfalls when quoting for or carrying out electrical work edpecially in older properties.

The biggest excuse they use is "its looped of next door and they neen to be in for us to pme it".

Under the old 16th edition, it wasn't reccomended that a smoke alarm should be connected to an rcd. And I would mention that to them that if there were a loss arising from smoke alarms not working due to loss of power and flat batteries. They may be called in court to share or take the blame for not supplying a reliable power supply intended for public use.

Within a week I would have a date for them to do a pme. The trouble is they keep changing the number for the network operator.

Yes are you?

Thanks. Would it be possible to temp connect an earth cable into the neutral henley thats already their and perform a ze test?

You said there is no earth, have you established what system is there? TNS etc? connecting to a neutral if you have no idea what the earthing arrangement is even if the reading isn't there could be opening a can of worms, have you got a picture of the cut out and meter we can look at before you kill someone?

Thats the whole point of the question. As already stated their is no earth connection or rod, so im pressuming its a tt system in which case i will rod, the aim of my question is is it possible to test just incase it is a tncs system and someone over the years has disconnected main cpc
