cable colour? 4

[mtchufi]

Dear all,
I ve a little simple problem with my installation.
As I’ve learn in collage and read some reference book, the green yellow cable is only used for the grounding cable.
What I find here is, the green yellow cable is used for phase. The Distribution cable color is yellow, blue, black, and green yellow. The contractor was connected the green yellow, black, and yellow to phase, and the blue to neutral. The ground is pulled sparately by a rope cupper conductor.The installation is 380 VAC 50 Hz, 3 phase+N.
My Question is,
1. Does any standard or rule that allowed the green yellow connected to phase?
2. How to Connect the system with that cable colour?
I can’t complain to the installator as I don’t have any reference.
I would thanks if any one could give me any PDF file on reference.

Regards,
MTCHUFI

I 've same idea with you, and I connected as what the vendors ask.
I put a large size banner of Warning letter/Notasion in the sub distribution panel, so every one who will work with this panel know that the connection inside is not standard and would pay more attention..
///Before you do that, read carefully the contract documentation since there may be something in the fine print. You may be required to contact the Client regarding this for its preference.\\\

You might apply proper colored tape to the wrongly colored cables at the ends and everywhere that the cable insulation is exposed. This is an acceptable alternative in the USA under NEC Rule 250.119 where green insulation is not available for grounding conductors.

jghrist,

That method is recognised in the UK, although personally I prefer heatshrink sleeving if it is a practical proposition to apply it (easier in the panel shop than the field!) because it does not degenerate into a mass of sticky slime over a period of years. Good thought.

Jbartos,
I've seen the contract of purching and istallation, but there is no subject descripted relevant with this case.

JSright,Scotty.
Its a good idea to give the coloiuring tape, and thats what have done here. If this methode (giving coloured tape) is an acceptable way, I think there is no any problem any more.
Heat srinking is good idea, but its difficult to realize here.

Any way, the Vendors was accepted with the colouring tape methode, thanks for your advise and suggestion.
