Domestic mains uses blue/brown for normal identification, is there an equivalent for 12v and 5v?
I'm setting up a system of relays to control 230v AC from a 5v dc relay (with a 12v one in between). Thus I have a psu which is outputting 12v dc and 5v dc in close proximity to 230vac. Easiest method for simple verification of what is what is by colour of wire (not to be relied upon but ideally as I'm doing it is rather use conventional standards!).
Is there a standard for colour coding 12v dc and 5v dc?
