Hi Glyn:
Two comments:
1) In a power cord, two conductors must be identified, one
being the protective earthing conductor, the other being
the neutral conductor (assuming a polarized connection
to the supply).
Here are the required identification colors according to
European Norms and the USA National Electrical Code
(NFPA 70), Article 400-22(c) (for jacketed cords provided
with appliances):
Standard Protective Neutral Live/Line
conductor conductor conductor
-------- ---------- --------- ---------
IEC/EN Yellow or Light blue Any (usually
Yellow/Green brown)
NFPA 70 Green or White Any (usually
Green with Natural gray black)
yellow stripe Light blue
So, a European color-coded cord is legal in North America.
(The Canadian Electric Code was similarly changed.)
(Several years ago, the NEC was changed to provide for
compatibility with European cords, so one cord could be
used in both Europe and North America.)
The NFPA alternative colors cannot be used for fixed wiring
in the USA or Canada.
2) "Harmonized" <HAR> cordage certification is available
only to cord manufacturers with a presence within the
EU. Other manufacturers must apply for certification in
each country which requires cordage certification.
Best regards,
Rich
