If you also have a 208/120v system, use 480/277v colors, or vice versa.I am working in a data center where the voltages are from a wye circuit. The voltage is 415V line to line and 240V line to neutral. Does anyone know what the color code is for this?
I believe most of the EU and now the UK have standardized onYellow Brown Purple used to be the industry standard for 277/480, but was changed to Brown Orange Yellow because in low light conditions, brown and purple were hard to distinguish. Since that is not a standard US voltage, I wonder what colors are being used for that voltage in other countries?
and to finish the CMYK, use black for neutral? (NOT!)Sounds like this service is going to become popular enough that a new color code needs to be designated.
Cyan, magenta, yellow?
Only for electric-vehicle chargers. The automotive industry is quite thoroughly entrenched with using black for grounded conductors.and to finish the CMYK, use black for neutral? (NOT!)

Jim 416/240 is a new to North America system that utilities and transformer manufacturers are beginning to offer, there would not be any existing wiring to tear out around here.It is pretty much useless to create a new 'national' color code, for phase conductors, unless you tear out and replace all existing wiring.
Ill add 'natural grey' or white phase tape on larger wire is a much more common neutral color for 277 neutrals not gray, around here that is.I know many electricians like to think Brown, Orange, and Yellow is a universally used scheme, but it isn't.
VW, Audi, Porsche, Volvo are all brown for the negative frame red for the 12V. I dont believe they use black.Only for electric-vehicle chargers. The automotive industry is quite thoroughly entrenched with using black for grounded conductors.

Wow yeah your really thinking it through.This goes beyond 416/240V. It deals with the vast number of already installed electrical installations. Any proposed color scheme that uses one of the existing common colors, of black, red, blue, yellow, brown or orange, would be a problem.
