Colour coding of wires for flexible cords
The colour coding of the wires for NEW flexible cords will be:
Brown = Active (Phase), symbol A, P or L
Blue = Neutral, symbol N
Green/yellow = Earth, symbol E

The colour coding of the wires for OLD flexible cords will be:
Red = Active (Phase), symbol A or P
Black = Neutral, symbol N
