575v

[Delcobob]

We are in the process of wiring some equipment that was brought in from out of the country for a manufacturing facility. The equipment is 3-phase, 575 Volts. My question: is there an industry standard color code for this voltage? I know it is not in the NEC but I also know I can't be the first one to come across this, and I want to make it obvious for those who might come behind me. Thanks!

No industry standard that I'm aware of as 600 volts is no longer used extensively in the U.S.

If it were me I would use a system that isn't already being used, so maybe Pink, Purple, and Yellow with a red tracer or something crazy like that.

You might want to check 210.5(C). Most likely you will have voltages other than the 575v and you will need to identify each.
