Bought some 3+E cable from a wholesaler a bit back, the colouring of that cable confused me too as it was Brown, Black, Grey and earth(Green)...

just wait till you get a 5 core (3+N+E) that now got the blue in it for the neutral. connect it up to an older install with old colours ( blue for L3 and black for N) and your in for a right bit of confusion!
Andrew Wildman:
Dave, the book is pretty good. Using the welder as the autotransformer was my idea and wiring in the volt meters was also not in the book but the book covers the rest. there is a bit of pulling together various bits that are scattered through the book to suit your installation but it is not too difficult.
DavidA:
Andrew,
Thanks. The book should be here in the next couple of days and I am looking forward to planning the project.
I've a pretty good idea of what will be involved (I was an apprentice industrial electrician many years ago, before I switched to Diesel mechanic) and don't see any big problems.
The voltmeters to monitor each phase is a good idea. I may steal it.
Dave.
Andrew Wildman:
look forward to seeing your progress. The voltmeters are just ebay cheepos but they are sufficient to ensure that the voltages are fairly balanced and to ensure that you are getting 3 phase.

When I started my apprenticeship TP colours were Red White and Blue neutral was Black earth was Green
a couple of years later White became Yellow
but as has been said the old colours were better in low light and dirty conditions
TRS was mucky Red, mucky Black and evan more mucky Green , get some founder dust on them and a bell set was your friend
personally I do not like the new style TP&N colours
