RE: Cabling from switches to LD units

["Keith Doxey" <lists.diyha@xxxxxxx>]

The first one was to illustrate a possible future module that would be
located in the wall box but required a neutral. I believe the existing Wall
Appliance Switch is like this although I dont have one.

Hello Keith

Thanks for the feedback

I can understand your second scenario where the three wire + earth would
enable you to control two LD10s
but I'm a little lost on your first one! :-)

If I use DIN rail mounted dimmer units back at my sub-consumer unit points,
what purpose does the
YELLOW - Switched/Dimmed Live out perform?
I'm under the impression  the dimming is done in the X10 unit and the feed
>from
Am I missing something or are you suggesting that the three core would
enable a normal non X10 dimmer to be fitted at the switch position?

I'm considering multi core cable from all the switch postions in all the
main rooms, back to the sub consumer unit points, in order to future proof
the installation as much as I can.
Would you like to hazard a guess at to what no. of cores/ways would be a
safe bet?

Cheers

Tracey
