Went to a job today, twin and earth, and it had been wired 2 plate, which of course meant that all the switches had the neutral taken to them.

WTF, if I had done that in my apprenticeship I would have been kicked off site.

Is this how things are done now, god I hope not.
 
What if customer wants to change from normal switching to dimmer?? Changing accessory now becomes more than a straight forward switch from one to the other.

Does this put it all into perspective at all, found this last week under somebodies floor boards
 
switch/loop at ceiling:
ring/radial:
swa/conduit
pvc conduit/steel conduit

we all have our own preferences and ways of doing things and as long as its to the regs and is fit for purpose it does not matter why we choose one over the other. different circumstances call for different approaches to the situation and methods
 
sorry I am more of an commercial/industrial installer
Why can you not do the 'loop into the switch' method in a commercial/industrial situation?

  • If the client wants the emergency lights switched separately (eg in a corridor where they want the lights to stay on during a light test) the auxiliary terminal would be fed from the keyswitch so you wouldn't be able to use it as live loop, so you'd need to link the loop in the back of the box which doesn't leave you much room to screw the lid back.
  • You'd have exactly the same problem with finding the rose which the switch wire comes off - why spend ages up a ladder or on top of desks when you can just take the switch off?
  • Looping in to the switch makes moving/rewiring individual circuits a lot more straightforward - strip the circuit back to the switch and continue it from there.
Obviously if you were wiring using singles you wouldn't loop anywhere.
