What is the best way to wire ceiling lights?

Arran Cameron
The ceiling rose junction box with its loop-in wiring is now really showing its age and is no longer a practical (or even safe) installation for most residents who wish to install fancy light fittings. It is still, however, the most common arrangement for new build houses and rewires, probably as the result of the electrician's training and how they consider it to be the norm or they cannot think of (potentially better) alternatives.


So, what is the best way to wire ceiling lights? Should neutral wires be taken to the switches or not?

    Unless it has changed, and it has been a few years, 1neutral,  2 lives and 1E , so long as both light switches are fed from the same breaker.




    3 core and earth is officially used for two-way lighting but is also used for powering fixed devices, such as extractor fans, that requires both a permanent live and a switched live.


    If 3 core and earth is used with two switches for a light fitting with half light and full light facilities then is there a standardised colour code for the wires that are permanent live, switched live half light, and switched live full light?
