Power & signal & control

[Chris Hunter <cjhunter@xxxxxxxxxxxx>]

I had thought we might run a box-conduit around all rooms of our
self-build, set surface-flush into the walls, to carry power & signal
&
control cables.

Then we could tap into them where-ever required, and easily replace /
update the cables as necessary, in the future.

But is there a better way, I wonder ?   Signal & power cables have to
be
kept apart.   Tapping into the cables would be a fiddle - cutting &
stripping & making screw-terminal joints, etc, etc.   And conduit is
not
cheap.

But future-proofing demands flexibility !

Is there a better way, I wonder ?

For example, separate bare mains wires, with crocodile clips, and / or
insulation-piercing connections ?

Or ... ?

And what size cables should I use ?

I'm not a fan of ring-mains, star-runs seem better ...
