So here's a little one for your consideration:
I have a 24 VDC system, with blue wire for +24 VDC and white-with-blue-stripe for 0 VDC
I have a sourcing input tied to a momentary pushbutton.
Wire-A goes from the input to one side of the PB
Wire-B goes from the other side of the PB to 0 VDC
Now the question : what colors should A and B be?
It may be argued that the input is a "24VDC Source), and A should be blue. Since B is tied to 0VDC, it should be white-blue
It may also be argued that the switch is transmitting 0VDC to the input, so both wires should be white-blue.
Finally, since this is a DC input circuit, there is an arguement that both wires should be blue, and white-blue should be reserved for dedicated power connections.
This one has me stumped. Any ideas?
