hi all I've got a man cave to get a supply to the earthing at the house is TNS, the man cave is steel frame, no spare ways in the house cu, it's a 30m run from meter to man cave, would you suggest a tt install or can I use the TNS, tt would be a pain to get the rods in ground as walls are underneath and ground full of Flint. Was going to split the tails at the meter I've already got swa in ground 3 core 16mm.
What would be best way for earthing in your opinion
Thanks
