Unused Earth Rod in Garage.

Zoomup

I was working in a new Mac. and Stone house today. In the garage is a nice new metalclad garage unit. It is supplied from the P.M.E. house supply and is earthed via the S.W.A. armouring and a third copper core. Under it is a 4.0mm2 green and yellow single wire running down to an earth rod that travels through the concrete garage floor. In the garage unit the green and yellow is stripped at its end but not terminated. It is just floating in mid air.

Why is it there? Was it left for a possible electric vehicle charger?

    I assumed that it is a rod. Why would anybody install an earth grid in a modern detached domestic U.K. garage concrete floor?

    Ah! Had I known about these things then, I would have had the rebar mesh in my garage floor (circa 60 sqm) made available as a foundation electrode. My question is why would you not?

    What is its purpose Chris? And why was it left disconnected?
