Mmm, an interesting reply, i'll bet your one of these loud mouths that never shuts up about your self importance and how good you think you are when your at work, in the wholesalers, in the pub, and maybe when you're on the other job. Lol!!!
In your comment about another sparky following me with regards to a fault and having to run up and down stairs?there are still homes in the UK that still have one ring serving every outlet in the home on more than one floor. A 30/32 amp ring main, probably the most dangerous circuit that exist in the world, but yet you laugh at the Yank system?
The niccy never had a problem with my choice of selection for circuit design, in fact they were impressed that I had managed to implement a wiring system without departing from bs 7671, and at the same time improve reliabilty without putting a whole floor in darkness, in the event of a nuisance trip from a split board. And also remain competetive, the main reason why I do domestic. Most of all, they didn't think I was bloody stupid as you put it.
And yes, I would include lights and power on the same circuit if the terminals were large enough in the light switches to take 2 or more 2.5.mm conductors, and the contacts were sufficiently rated along with the lighting accessories. Without using a fuse spur. I can't see how that would constitute a departure.
