[QUOTE="AnthonyP, post: 467844, member: 30444"] Morning folks. I have been a recommended a good electrician but he is only able to come and see me next Thursday. :( While I am waiting I would like to do more fault finding, because the issue is that as soon as the RCD trips, the house alarm goes ballistic because it thinks somebody is trying to bypass it. It went off once at 3am and today at 7am....I apologised to the neighbours by they were not happy (understandably). Went to bed last night and before doing so, I switched off the 4 x MCBs to the right of the RCD: 1. Electric shower (we never use this, it does work, but we just don't use it) 2. Sockets first floor (on the image it is on, ignore, at the time of going to bed it was down / off) 3. Lights 4. Wall lights So only the Ring Circuit 1st Floor and Ring Circuit Ground Floor was on. And at 7am, the RCD tripped. [IMG]https://talk.electricianforum.co.uk/uploads/imageproxy/yA5Nazh.jpg.4d854c334faab9e52404ad8e6611e95e.jpg[/IMG] My plan is to repeat the above experiment again, but this time, in addition to having the 4 x MCBs to the right of the RCD in the off position, I shall disconnect anything plugged into the mains ion the 1st floor. I am wondering if a lose wire is touching the back box or earth? We had some screwless sockets installed about 7 months ago, perhaps that is the cause? [/QUOTE]
