Thanks for all your replies. In short the answers I have received range
from
- EN60950 will let you use black and white for internal AC line
wiring
to - HD384 series documents dictate that line and neutral must be
blue and brown
I am left wondering whether the HD384 requirement apply inside
equipment, or whether the situation is similar to the North American
one, where the colours specified in the electrical code apply to
premises wiring but NOT inside equipment (unless called out in an
equipment standard).
Again my basic question, now slightly longer: Can I, in spite of HD384,
use black and white AC line wiring INSIDE a CE-marked, EN60950 piece of
equipment???
Thanks again for your help.
