White with ORANGE stripes is used for grounded (current carrying) AC circuit conductor that remains energized when the main supply circuit disconnecting means is in the off position (NFPA 79, Article 13.2.3.2).
The color GREEN with or without one or more yellow stripes is used to identify the equipment grounding conductor (NFPA 79, Article 13.2.2.1). The use of the Green with Yellow is a user preference. For equipment being exported, the IEC requires Green with Yellow stripes.
