That’s a 25mm2 earthing conductor run some 20m along a border hedge to an electrode at the rear of the building. It is a permanent, recent installation. When I commented on it the contractor lost his cool and screamed “what the hell is wrong with it”? I thought that the answer was obvious but my written response on behalf of the client is to be framed within the context of 7671. I have no difficulty in digging up the relevant regulations but they are subjective in nature. Anyway, all good fun!
