Use of a black core for neutral is strongly deprecated since it is now a

Isn't that totally crackers?

It's the sort of thing that could only be dreamed up by the EU.

Does seem strange to me too - since most used blue for neutral on the old
colours when using three phase wiring for this purpose.

But I can understand the reasoning behind it. It might make sense to have
triple and earth available for this purpose where the colours weren't used
for anything else. Or even three browns would make sense.
