Just to let everyone know, I had a conversation with a UL Engineer. I was using the wrong section of UL508A, which was for Industrial Machinery. For Control Panels, only the ground wire has a specific color assigned. We are free to use European wire colors for all AC wiring inside the

I stand corrected in regards to UL508A. It sounds like UL 508A is behind the times. I have had commercial and industrial air conditioners UL Listed with European wire colors. UL 1995 does not force internal wire colors to all black. I didn’t realize that UL 508A did. If the panel is for a

I just found out that since we build to UL508A compliance, the Hot wire must be Black and the Neutral must be White or Gray (UL508A 66.5.3). It looks like the Ground wire can be Green or Green/Yellow. I don’t think these wire colors will work for Europe. John Cochran From: emc-p

Hello John, Brown, blue and green/yellow are not a violation of the NEC or CEC. You can use them in North America. The NEC specifies only a few wire colors. Green and green/yellow can only be used for ground. White and grey are reserved for neutral. No other colors are reserved for a
