What color does the IEC mandate for 24VDC wire?

What color does the IEC mandate for 24VDC wire? The best I can come up with in my research is brown and grey. But using Brown for line and also for 24VDC control wire can't be right...is it?

I am not aware of any mandatory requirements.

Yes, in some Wiring Code like BS 7671, brown and grey are mandatory for L+ and L- in DC power circuit. It would be fine if just goes to POWER circuit. The colors in DC control circuit are not defined.

I don't know if it's manditory but around here most of the 24VDC, and most other DC voltages wires are blue. Just thought that was the standard.

Sorry but I had to laugh when I saw a "BS" code

I imagine a lot British rules are "BS" though:lol:

Blue is used on this side of the pond. IEC refers to standards mostly used on the other side...
