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?
