Is there a standard for colour coding different ratings, or is it each manufacturer to their own?
I'm trying to make some diagrams of a CU and I can't seem to determine which colour goes with what rating.
Does anyone know of any standards?
Or is it just a case of picking one manufacturer and sticking with their scheme?
