RE: Future proofing cabling to downlighters with C-BUS

Andy,



I guess your garage will be close to the kitchen say 10-15m. If so 1.5mm
cable will be fine as you will only have 4 lv lamps on each transformer.
1.5mm 3 core is easy to get hold of. 2.5mm 3 core isn't as common.



If you ever use c-bus DSI you will need a cat5 to each group, Therefore 2
runs.

Subject: [ukha_d] Future proofing cabling to downlighters with C-BUS



Can anyone give me some advice on future-proofing a kitchen wiring
install for lighting?

I am installing 8 mains downlighters into the kitchen which will hang
off a two CBUS 1A dimmer channels.

If I wanted to move to dimmable CFL's in the future and providing that
the C-BUS hardware was available to do this, what cables do I need to
lay now.

I have already wired using 2.5 T&E in case I want to go LV for
whatever reason using a common tranny in the garage, but I understand
dimmable CFL's will require a 3rd wire, what is this for, heating element?

To play it safe now would it be advisable to lay some CAT5 along the
T&E? or should I be using 3 core cable?

Any ideas whats best to do now for the future?
