[QUOTE="kme, post: 23893, member: 113"] Callout today - "sockets keep tripping" TN-C-S. twin split load CU. 4 bed detached (with cellar & garage) total no of MCB`s - 3!!! 2 of them are lighting (30mA RCD protects) other is a 32A MCB via 30mA RCD - All sockets in house on 1 ring!!!!!! EVERYTHING disconnected (trust me guys!) Phase - earth reading of 70K ohms! Eventually found an outside wall where back boxes are rusted, and copper is green :) Take face plate off. FACE PLATE is reading 700K P-E while not attached to ANYTHING. Could the moisture have got at the cable? N-E is good, which suggests not, but I can`t think of anything that would cause a leak of that size (it stays approx the same at 250, 500 or 1KV!) Any input appreciated.... KME [/QUOTE]
