Subject: RE: Cable colours for DC wiring
I would like to know this also, as I can find no definite standard for
DC wire colors in Europe or US. We did have one system evaluated in
Denmark, and they insisted that the +24VDC wire be blue and its return
be white. I tend to go with the colors used with ATX power supplies:
+5V=red, +12V=yellow, +3.3V=orange, -12V=blue, ground=black.
Thanks,

Subject: Re: Cable colours for DC wiring
It is my understanding that there is no standard for colours except for
safety and earth ground type connections being reserved with greens,
yellow bands, etc.
However, my preference from working in PC power supplies has always been
+12,15V red, return red/black
+5V orange, return orange/black
gnd, black
-5v blue, return blue/black
-12,15v purple, return purple/black
Then all the signal lines were leftover colours.
Special 'high voltage' I used red/striped with white just for clarity
