[QUOTE="Sidewinder, post: 438149, member: 9512"] OK, apart from the excellent advice already given, an RCD can be susceptable to an upstream fault causing "nuisance" tripping, it shouldn't, but it can. Now if, the both properties have closely linked earthing and supplies then there can be interaction between the two properties. This can happen if they are both TT, or one TT & one TN. If, the house is being refurbished, have the "builders" removed the means of earthing from the property? You could do with a competent electrician with some test gear there to look at the fault. If the builders are working, it shouldn't take long to identify the issue, and, the electrician could go and have a quick word with the builders too. [/QUOTE]
