[QUOTE="AJS87, post: 522143, member: 34371"] I have disconnected the earth and carried out a Ze. There is no requirement to carry out a Ra just because it’s a TT system. The test can be carried out as normal practice in a TN system. Your not getting my point. It’s perfectly acceptable to use the building structure as the earth. I have a 10mm earth from MET to structural steelwork and looped to a rod. Bonding or not. The rod will not be providing the bulk of my earth. The steelwork will. [/QUOTE]
