Hello I am currently wiring a mains powered chassis. I have relays which use mains voltage levels for controlling other mains voltage relays. I would like to differentiate between the signals by using striped brown-red, brown-blue cabling etc.

This has to go through compliance testing. Do all 'live' mains voltages need to be coloured solid brown?

Edit: This is currently a product destined for the EU market.

No it varies by country and voltage:
