[QUOTE="refael, post: 541284, member: 36250"] The only thing is all the other circuits in the 3 story house are having no issues and this particular circuit is connected to the same neutral and the same phaze as other working circuits. There is one other interesting find i forgot to post, the way the panels been wired theres 2 neutrals one connected after an rcd and one that's coming straight from the mains. (something if i can find the issue that would be rewired to include all circuits on the rcd) When the rcd is switched off and that 2nd neutral bar is isolated (or should be) there's still a reading of 150 beetween phases and neutral there is no resistance beetween the 2 making me believe they're connected somewhere in the system (not in the panel, and after the breakers) This tho wouldn't explain why one circuit would cause all the issues especially since the problem circuit is on the neutral thats overriding the rcd [/QUOTE]
