What are the changes to the colours of fixed wiring?
The changes to the colour identification of conductors in
fixed wiring were introduced, by Amendment No 2 to
BS 7671, which was published on 31 March 2004.
The changes were effective from that day, however up
to 1 April 2006, it is permitted to continue to wire new
installations in the present wiring colours to use up
existing stocks of cable.
