[QUOTE="sparkyt, post: 94067, member: 2055"] what do u think of this one..... Installed new ring circuit only 6 skts and aprox 35m end to end. anyway testing cables before connection and come to i/resistance. 500v L-E varying reading between 10-15 MOhms. very strange i thought so went round removing all sockets and testing legs between skts. all clear. Great so connect sockets back up but leave hanging. test again all clear. now i start to fix back the sockets one at a time. every time i fix one back i perform i/r test. for every socket i fix back the reading gets lower and lower. so skt 1 fixed back and reading of 91mohms. 2nd skt screwed back and test again 83mohms and so on. last skt screwed back an i/r value is now 10.3 mohms L-E!!?? what on earth could be happening? no cables are dammaged and the boxes are dry lining and therefore plastic. when connected into the board keeps taking out rcd. tried i/r readings across all skt terminals too whilst disconnected. all fine. can anyone think of any possible reason why this could happen? headbang [/QUOTE]
