New way to wire lighting circuits

IIRC, in the USA there is a proposal to require a neutral at the light switch, for future flexibility for electronic controls.

In the UK, as others have already said it is permitted but not required.


There is also a lot of VERY ill informed demand for neutrals at the light switch to "improve safety" Circuits with the two conductors well seperated can give rise to electromagnetic fields, that may be harmful to health.

With a conventional 2 wire drop to a light switch, the "go" and "return" conductors are immediatly adjacenr and no significant electromagnetic field results. That however does not stop the mumsnet types from demanding neutral at every switch to "prevent rays that might harm a baby"
