Colour coding of electrical panels and transformers
Colour coding of electrical panels and transformers
(OP)
Hi everyone
I am trying to find out if there is a standard out there that states which colour electrical panels and transformers should be - according to their voltage.
At one company they make the 380V panels/transformers orange, 11kV panels/transformers green and 66kV panels/transformers grey.
Is this according to a certain standard?
I am looking for a electrical colour coding standard that I can use in a coal mining environment.
Thanks in advance...

For the all types of panels today in EU : standard color is RAL7035, some type of gray, before was RAL7032.
Water industry: blue and white .

As far as conductors go, yes there are standards:
Others can correct me if I'm wrong but standard practice is for 480V systems:
Brown Yellow Orange for Phase Conductors
White for Nuetral
Green for Ground
120v/208v systems:
Black Blue Red for phase
White for nuetral
Green for ground

I've never seen orange equipment but I have seen plenty of examples where for some reason clients put the aesthetics of a project as a higher priority than the functionality of it.

So true, once worked on a project where the Architect wanted the fire alarm break point changed to green as the redd stood out too much !!!!!
