Another pondering question from me
I'm just thinking about first fix electrics. We're going for radial circuits for all loads, including lighting.
The lighting will be controlled by Cbus Dimmers and Relays back at the cabinet as required.
I've done a few 1st fix wiring jobs over the years (inc three with Cbus) and always used 1.5mm cable to allow for potential loads from say large banks of halogen downlighters.
BUT, with the LED and low voltage being commonplace (and part of regs) I really cant see much point going over 1.00mm now for the lighting radials to each room.
Max run is going to be circa 25m.
All enclosed in service voids (uninsulated) behind pb.
I know the benefits are pretty limited. Perhaps only; 1)Slightly Cheaper 2)Easier to run 3)More room in the cabinet.
Am I missing something?
