Hi,
Please could you help my friend, who is having electrical work done at his house?
…The ground wires in his house all go to the consumer unit (main fuse box) and there they connect to the Neutral of the incoming mains power supply. In other words his "earth" is the neutral of the mains.
He is now going to Install an electricity kiosk at the edge of his land where the incoming supply and the meter will go. He asked the electrician what to do about grounding, and he said "nothing". Is this correct?
Anyway, Subsequently, his electrician brought another electrician over for advice, who said he actually needs to place two grounding rods into the ground, one next to the kiosk and one next to the property, some 35 m away.
Do you know if this is correct?
Would I be right in saying that the determining factor here is the (albeit rare) situation of “Lost Neutral conductor” in the three phase system somewhere “upstream” of his supply? As is known. “Lost Neutral conductor” is the scourge of mains supply systems the world over, since it can mean Live to Neutral voltages going up to Line-to-Line levels, that is, UK mains Live-to-Neutral in someone’s house could go up to 415VAC.
Presumably, if someone has a local earthing rod near to their house, then these overvoltages would be less likely during situations of “Lost Neutral Conductor”?
