[QUOTE="PheonixFoX12, post: 504589, member: 33378"] The upstairs lighting circuit controls the second floor and the loft circuits on a 16A MCB if that’s what you were getting at if not please explain :) Yes 4 MCB’s are directly adjacent to each other with an RCD as well. Assuming that the MCB’s are fed from the RCD. There are 2 separate circuits one lighting and one for the alarm. I suspect that those two circuit are not fed from the RCD since they are not adjacent to it. On this topic can someone help me with this, as I was watching tv the RCD tripped completely randomly. All the sockets and lights went off except the downstairs lights and alarm ONLY which explains my thought of them not being RCD fed. But why did it trip randomly? [/QUOTE]
