2019 my house was finished. PEA came and checked the earth rod was correct length, i believe they are marked. The rules had changed a month before, my electrician had, had a house pass a month before with no problems but it had changed, any underground cable had to be the triple insulated cable, and all twisted cables from the road/meter 175mts had to be clamped. All I had to pay extra for was the new underground cable. my electrician did the extra work free. .
NEW UNDERGROUND CABLE to house.
