broadgage:
Presumably the earthed side of a DC supply is still blue ?
So two wire DC negative earth would be blue for earthed negative and red for positive.
And two wire DC positive earth would be blue for the earthed positive and white for negative.
And three wire DC would be red for positive outer, blue for earthed middle wire, and white for negative outer.
Blue for positive "just seems wrong" even if it is the earthed side of the supply.
Yes, no change to Blue for mid-point (M) or neutral (N) conductors.
Blue is only positive in negative-earth situations, and the conductor is identified as "M" not "+".
Not very keen on pink for functional earth either, cream was fairy well established for the minority of installations that needed it.
