I seem to have located a radial circuit in the loft conversion. The Circuit is the Ring circuit from the Middle Floor which supplies only 4 single sockets on the Middle Floor, 2 single sockets in each room. In Each room there is a ring circuit and a spur.
My Problem is when i Removed 1 of the 3 double sockets in the loft and tried to do L/L, N/N and Cpc/Cpc, I got a reading on the cpc/cpc but no readings on the L/L or N/N. So I left the socket 1 disconnected and switch the power back on and tested the sockets. Sockets in room one - ring power ok, spur - no power, room 2 - power in both sockets, loft power only at the disconnected sockets on 1 wire only. When reconnected the socket wires I get power back in the spur in room 1 and the other sockets in the loft
The wire supplying the middle floor is the grey strand 2.5 mm and the one supplying the loft is white 2.5 mm T&E.
I have opened all the sockets in the middle floor and there is only two wires in one socket and 1 wire in the spur for both rooms - all in grey wires. There is no 3 wires in any sockets.
At consumer unit: Cpc to cpc - 0.41 ohm, L to L =0.34 ohm, N to N= 0.32 ohm. I also get a resistance of 0.56 ohm between the L and N ends.
With Figure of 8, R1+Rn in room one is 0.05 at socket wired as a ring and 0.66 ohm at the spur coming back from the loft, second room is 0.07 by socket wired as ring and 0.36 at spur socket and in the loft it is 0.47, 0.33 and 0.19 at the first socket.
R1+R2 is 0.12 at consumer unit then bedroom one 0.23 ohm at the ring, 0.86 at spur, Bedroom 2 - 0.47 at the ring socket and 0.19 at the spur socket and in the loft it is 0.63, 0.49 and 0.31 at the first socket.
IR - L to N - 0 (interconnection somewhere), L to CPC >299 and N to CPC >299 Mohms
I need to find out how to circuit is wired or where the loft connection comes from. My job was to add a couple of extra sockets as the loft conversion is being extended.
If not I might have to run a new circuit to the loft from the Consumer Unit. I have found a boiler in a cupboard in the loft at the end of the day as I was leaving, and a quick switching off the MCB for that circuit and the boiler was still powered.
Will appreciate any ideas or thoughts on this circuit.
