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.

1. 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.

2. 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?

Er, what exactly is the question?

Many thanks for any assistance.

Right.
