Just moved into a 1900 3 flr house in West Yorks. We are renovating the top floor first and I am uprating the electrics. In the course of checking out the cables under the boards I found the 1st floor lighting circuit appears to consist of one-core cables. It all appears recent enough and is the same grey and age as the 2.5mm ring circuit stuff that's there too. Is it a bodge?

It's how it used to be done years ago. Provided the cable has two sheaths
- which it probably has being grey - I can't see the problem. How have they done the earths?
AFAIK single cables are designed to be used in conduit. Maybe someone had a cheap source from his place of work :-) probably ok ...

Probably not.

No, you're thinking of single sheathed cables, 6491X. The OP's cables are probably 6181Y\6241Y, double sheathed, with or without CPC conductor.
Surely you didn't expect to get away without me having my standard comment on this!
Although common practice, the use of singles (because it usually implies separate routing of neutrals and lives) is deprecated as it interferes with induction loop hearing aids, which is no longer a PC thing to do.

Does it really though in practice? You would have to be drawing some pretty hefty currents or be standing very close to the cabling to have a noticeable effect.
Do many use an induction loop in a house?
Plenty. There are portable induction loop devices now available for use with telephones and televisions etc. Remember, it may be your neighbour that wishes to use them, rather than yourself. Subjecting your hard of hearing neighbour to relentless 50Hz buzzing might not be considered sociable behaviour.

They are fitted for people hard of hearing to use a TV/radio, without the whole family and street having to listen in.
The one turn loop you can easily make using sheathed singles creates a field which extends outside the house too, so you can interfere with neighbours' ability to use induction loop systems too. Run a lamp dimmer on such wiring, and the effect is 10 times worse.
With my experience of induction loops for broadcast use, I'd say that's unlikely. Possibly in a flat, I suppose. But a properly designed induction loop system for audio purposes should notch out 50 and 100 Hz anyway - it's of no use for hearing purposes.

If I didn't know better I'd say you were a troll! ;-)
I'm not going to comment, we've been here before....
Did'nt we have a similar thread a few weeks ago ?
