Is there any clever way of getting a cable through a hidden stud
behind plasterboard? I want to feed a lamp from a switch mounted on
an internal dry-lined wall but unfortunately there's one piece of
timber between the switch and the light.

It's a very low current requirement, 3.5 watts at 240 volts so
something like 15mA.
If it's near the ceiling, you can drill through, but other than
that...

You need to make a hole in the PB, over the level of the stud,
get the
cable through, then fill the hole.

If it is a stud you are trying to pass cable through then you
little option
but to cut out a small section of plasterboard across the stud.
You can
then either notch the stud or drill though it to pass the cable.
You then
need to cover the cable notch with one of these;

If you cut the PB with a multi tool at an angle of 45deg around
the edges
the piece can simply be replaced using some filler to both glue it
in place
and to make good.

The trouble is I'm not sure we have the same/original coloured paint.



You've made my day.Â*


It's possible (and I think flying pigs are involved) that you can
remove the switch and backbox, and drill diagonally through the
stud. Somehow feed a cable through and fish it from the other side.

Or, you can repaint the wall.

The other possibilities are to drill straight through the wall - you
haven't said what's the other side. A cupboard would be good!

Or drop a cable down and run it behind a skirting board. Then
somehow fish it up to where you want it. That might actually work.

although not a "permitted" cable route unless there were already some
electrical accessory positioned in the skirting.


I've often thought that it would be very useful (ignoring Part M) to
use industrial type systems at home. You can buy cable ducting that
looks like skirting, but slightly deeper and contains protected
busbars and separate compartments for other cabling. Adding a socket
means nothing more than popping off a cover, cutting a section out of
it, clipping it back and clipping a socket into the gap.

That would be so useful for domestic situations. I put sockets, in
sufficient numbers, in useful locations, but over the years,
re-arrangements have left most of them behind furniture!


Nothing stopping you using dado or skirting trunking at home... if you
like that boxy PVC aesthetic :-)


The version I was referring to includes busbars, so sockets can be
positioned anywhere, later on, without any wiring. So sockets sit in the
front of the trunking. When used as skirting, it'd fall foul of Part M
of the building regulations, requiring sockets to be at or above 400mm.

Okay, you could put it in a room, without triggering part M, but doing
the lot would suddenly put it into coming under part M and its height
requirement.

The particualar one I saw was meant to be used as dado, but would have
been good as skirting too - and looked a lot better for home use than
the majority of ones that I have seen.
