An electrician I sometimes work with asked the NICEIC support desk
this.
In
his case it was when he was 2 waying a light. There was no red
sleeving
on
the existing switch wire and the 3 core and earth he was installing
for
the
two way was in the new colours. He was told to use brown on the new
wires
(a
bit obvious) and red on the existing black wire.

I know that is not a reg and only the NICEICs interpretation of the
regs.
It
seems a logical enough approach though.

But brown does just as well. As the colour brown has now been chosen to
signify a live conductor in the new harmonised scheme. But, also, the
colour red can be used in a none mixed scheme to signify a switched live
conductor, which gives no reference to black or blue on the switched
live
to
any fitting, making it easier to distinguish all the switched live
conductors. Brown supply. Red Switched supply. Blue Neutral.


Make your mind up.

If you have red in a non mixed scheme then you are using the old colours
and
only the old colours. Brown is not one of the old colours. By adding brown
you have a mixed scheme.

I didn't word that properly, did I? I didn't mean to use the phrase "a none
mixed scheme" in there. What I meant was, even in an installation which
uses the new harmonised colours, you can also use red to distinguish your
switched live conductors. So giving Brown as the supply. Red as the
switched live to the appliance and Blue as the neutral conductors.

Is that clearer? Let me read through that again. Yeah. That makes more
sense.
