Wiring for switches
 

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?

Many thanks for any assistance.

Best regards.

Is this conduit made of metal, or plastic? How is it fitted to the
boxes? How much damage do you want to do to the walls?

Assuming it is plastic, the best approach is generally to make a
wider channel and replace the conduit with something suitable such
as plastic capping or one or more bits of plastic trunking. If it is
metal, the best approach is generally to lay a new run beside it
with plastic capping or trunking.

An alternative is to run singles down the existing conduit and
install a junction box at the top of this, where you can connect
twin and earth. This avoids damaging the wall.

Er, what exactly is the question?

Right.

What about Part "P"

Replacing a part will leave the rest in an outdated state. Are you
competent?

I assume you're replying to the OP, try harder in future.

I assume Lurch is menstruating over the next few days. :)

Thanks David. Had to damage a slight bit of the wall as there was
some obstruction in the conduit, but all working now.

Best regards.
