[QUOTE="jimmybobbob, post: 395054, member: 26091"] The RCD and DB are relatively new about 2 or 3 years old as I understand when the house was renovated and the DNS installed a new 4 wire supply underground getting rid of the old over head supply. As other post's have said my initial thoughts of protecting livestock and the u/g cables was the same thinking as others (but why on a PME) I can see the logic for the old 4 core cable to the house as I wouldn't rely on the swa as an earth to get the correct disconnection time, hence putting the 300ma RCD in.................
