OK, I'll bite,
Would someone like to tell me how people that design and make electrical panels with PLC's and other Low voltage devices are supposed to internally wire a panel.
I'm talking 12, 24 and 48V AC.
I think you guys know my thoughts already on the constant changes being made to wiring colours.
New Zealand used the British standard for wiring control panels up until 1992, in factories at least.
In '92, all that went out the window, now factories that I've been part of, have added on bits and pieces with "new colour codes".
Phase is purple and the Neutral Black w/White stripe.
I wish someone would make up their mind, this is confusing us all to hell!.
But on the same side of the coin, I've also made a point of labelling the panel with a decal stating the colour codes used throughout the installation.
As for the chosen EU colours, they couldn't be a worse combination IMHO, at least with R-Y-B you had some idea of the colours in poor light, it seems like some clown that has never done a days work as an Electrician dreamed that idea up.
Just my $0.02 worth.
