[QUOTE="Ardet R, post: 462587, member: 30040"] Welcome. I would suggest that perhaps this was a global test on all those circuits at once and the single item of failure therefore shows up on all circuits. The result for LN cannot be correct if all items were not disconnected from the circuits and the ones to earth are very unlikely to be correct if everything was disconnected, so there is an anomaly here. There are numerous items that can generate that level of reading, connected electronics is a good one. Normally, but not exclusively, a low IR result at the 1 - 2 level and <0.1 may be a damaged cable but intermediate levels would have me thinking about connected loads. [/QUOTE]
