Rubbish. Whether to do that or not, once we are out, becomes a
commercial matter for the company involved, rather than purposelessly
being forced upon them.

Good thinking. Let's go back to when every country used their own
colours
for mains flexes. Freedom of choice is more important than common sense.

To be fair the change to colours for fixed wiring was a stupid one for
the UK. Blue is neutral in the current system and a live (3ph) under
the old, causing huge risk of confusion on industrial sites.

There was no need to standardise the colours for fixed wiring across
the EU and flex/portable wiring had already been standardised.

Of course there was, how would British electricians get jobs on the
continent if everything was different to what they had been trained to do?

Pre-standardisation, I managed perfectly well to design a control panel
to Irish standards; which was build and internally wired in the UK and
shipped to Ireland, where I supervised its installation.

I also did many panels to American standards (used all over the world in
Oil and Gas), British Standards, German Standards, the Standards of
various middle-Eastern and Asian countries, etc. What is the problem?

Fixed wiring is a good example of where sticking to our own standard
would have been more sensible.

We didn't change much.

We ended up with huge numbers of mixed installations in industrial
settings, with colours that have different meanings between new and old
- a recipe for mistakes, requiring labelling of various parts to attempt
to remove ambiguity.
