I never cease to be amazed by the things I don't know, but I am
afraid that (so far as I am aware) the use of yellow only is not an
acceptable alternative to green and yellow so far as protective or
equipotential bonding conductors are concerned in any of the European
equipment or building wi

Hello from San Diego:
One of our subscriber colleagues has pointed out that
my assertion that Europe uses yellow as the color of
the earthing wire is incorrect.
I recall when the green-yellow was agreed to for
power cords and internal equipment wiring. My
recall was that both yellow and gr

In North America, the earthing conductor is described as a green wire with a
yellow stripe, while in Europe it is described as a yellow wire with a green
stripe. Fortunately, there is enough tolerance in the specifications on both
sides of the pond that a single solution works in both locations.
Hello Peter,
IEC 60173: Colors of the cores of flexible cables and cords, is still active
and provides a coloring scheme for earthing conductors that is referenced in
many other IEC standards like 60204.
