Mains Lighting Wiring Regulations Question

["Kevin Hawkins" <lists@xxxxxxx>]

  Can someone familiar with BS7671 - the IEE 16th or whatever the
latest
is - comment on the following..

    What is the situation with potentially removing the
switched live feed
>from
SINGLE new wire from the lamp side and running it back to the fusebox
where
it will operate from say a relay or LD11 or similar ?  If I have
several of
these to do can I pair them together into one cable with red/red twin
and
earth - or more if there are multiway cables ? I don't need switching
wires
back to the panel as that is already handled elsewhere.
    Do I need to use twin and earth ie is the earth needed
for regulations ?
The neutral feed to the lamp would be provided however it is already
provided (ie undisturbed). This may be a daisychain arrangement I am
guessing.
    Would I need to fuse each leg done this way if they were
switched by
something like a relay or could I have a single fused feed to several
relays/ lights ?
    Would the same apply to switched 2A sockets ?? (Just
running a switched
live back to the fusebox and leaving the earth/neutral in a ring type
configuration )

  Cheers Kevin
