Old and New three phase board wiring

[Paul Williamson]

Hi All
Can I get some advise please.
Is it OK to install a new lighting DB with all new lighting circuits wired in all new colours, Brown, Blue and Green/Yellow, all the other boards are in the older colours. Black, Red and Green/Yellow.
The question is, the DB is a 3PH & N and the tails have been wired to one of the old DB in 25mm2 using the old colours, Red, Yellow, Blue and Black as the Neutral and in single core cable, not double insulated.

I would like to find the answer in the IEE regs but unable to find anything.

Thank you
Paul

yes you can, if you look at K2.2 of the blue OSG it gives advice on labelling the conductors

And stick a label on the board saying mixed colours used in this install, or something like that
