there is no fix standard on wiring color code, different country different std

for single phase,
normal 3 core wire:
Brown=L
Blue=N
Green=E

wire pull by electrician/ provided by developer:

red/yellow/blue=L
Black=N
Green=E

That's the confusing part...


red/yellow/blue=L
Black=N

or

Blue=N
Black=L

easy rules:

Earth= always green
Neutral= No colour, ie black or white
Live= Coloured except green!

the different colour of live wire used by the electrician is to differentiate type, zone etc...

Thanks all for the help. I "survived" and successfully installed my ceiling light via DIY.

Very helpful information, indeed!
