Hello,
I am trying to replace a bit of wiring in my mother's house - the present stuff has been there since the year dot.
- The hall and landing light switches - double switch in hall, single on landing. Presently operate as double operates hall and landing, single operates landing only and either will switch on/off the landing light.
The hall switch has three cables feeding it - one 2 core (red and black) and two 1 core cables (both red). Looks like a two way and single switch. The black and red feed the two way and the two red singles feed the other gang. There is is a short red cable linking one of the reds to the red of the double core.
The landing has a two way switch with one double core (red and black) and a single black. The single looks like it goes up to the attic to the landing light fitting.
- Double switch in living room - one works dining room light, the other the living room. Did have a two core feed with another cable linking it to another switch through the wall that worked the kitchen light, plus a short link between the gangs.
The conduit is too narrow to put a couple of cables in, so is the best solution to simply cut a couple of wider channels in the plaster, put in wider conduit and new twin and three core ( + earth) as appropriate?
Many thanks for any assistance.
Best regards
