Discuss Removal of Light from Circuit with Looped Neutral in the DIY Electrical Forum area at ElectriciansForums.co.uk.

    So looking for some advice in advance of getting a visit by a local electrician to see what the general consensus is and whether the job ranges between some quick and easy or full rewire.

    In the Lounge of a 1950s semi detached, there are 3 lights operated from a three gang switch. I would like to remove two of these. Wiring is the old Red and Black, but not too old I gather early 90s) from the previous owner (modern Consumer unit too).

    Behind the switch, the live loops into the switch with single core round (two layers of) insulated wire, then separate live + earths go off to each of the 3 lights. No Neutral wires to be seen however. At each of the light fittings, there is a live + earth and a neutral + earth. I assume therefore there is neutral loop connecting the lights (heard this is often done with rooms with many downlighters).

    Something like this the rough diagram attached

    So I have two questions:

    1) Is this method of wiring still allowed under (current) regulations for this application? Or would I need a rewire?

    2) What would be done to remove to two lights from the circuit? Would have said it would be remove the live between the switch and the light, and link the neutral in a maintenance free junction box (under floor boards). But since there is only one neutral wire going to each fitting there must be a juntion somewhere else feeding these.

    Many Thanks

    Its a shame most people who play with their electrics aren't as well informed as yourself

    There is no set method of wiring lighting circuits,they can and are done in various ways which include circuits similar to your current method,take the advice above and crack on
