Jim, You are correct in that IEC950/EN60950/etc. does not specify primary wiring color schemes, but only the earth conductor(s). Actually, UL1950 does not specify black/white either. That is accomplished in the NEC. Conversely in the international markets, I believe the blue/brown color scheme is described in HD-21, HD-22 or IEC227(IEC950 Annex P). I don't have those documents so I can't be sure. Anyone out there who has access to these documents or knows specifically where this blue/brown color scheme is specified, please shed some light on this. Comments would be appreciated.

EN60950 only limits the use of green/yellow wiring. As far as I can see, it does not mandate the blue/brown colour code. Does anyone disagree? Thanks.
