I have two line wires coming out of the top of the 'Sockets' B32 MCB. One of those line wires connects to 3 sockets in the bedroom and the other wire connects to 5 sockets in the living room.
Each socket takes two line wires, one to power the socket and the other to pass the current onto the next socket. On the bedroom circuit, the third socket, which is the last in the chain of sockets, has wires that carry the current on, but it is not clear where they go. I will assume it connects back to the consumer unit. If those wires that carry the current on are connected, the 'Sockets' MCB's RCD trips.
The situation is the same on the living room circuit. After the last socket (the fifth on in this case), the wire carrying the current on (again I'm assuming it goes back to the consumer unit) will trip the 'Sockets' MCB's RCD if it is connected.
If the wire carrying the current on is not connected on both circuits, all the sockets are powered.
What do you think could be causing the trip? If both circuits are rings, could the consumer unit be causing the trip?
