What labelling needs to be on a new CU?

Ive got the RCD/date of inspection/circuit info labels, I know i need a label for different coloured conductors.

Do I need a label on the MET? Also, the supply is through a DP isolator, does that need a label?

Ive got an Elecsa assessment shortly so needs to be right :crazy:

Thanks.
 
The mixed colour wiring sticker annoys me. If you don't know what colour means what on both the new and old colours then you have no business poking around in there.

Whilst I don't disagree there is more scope for confusion in a three-phase installation given that what was a phase conductor is now the neutral conductor and what was the neutral conductor is now a phase conductor (or line conductor to ensure that my terminology complies with the 17th Edition!).

what are these new colours? are they changed from red/yellow/blue/black?
 
I use PIRform for my certs - and this has the option to print off a circuit schedule, which I then laminate and pass to the client to keep by the CU. This includes my contact details.
 
Think Tel and I prefer the more technical approach to circuit labeling, on the back of one of these. They can also be used for any design calcs and of course any cartridge fuse replacements, the silver paper just about covers any load size

and, most importantly, you can use the proliferation of stickers to hold the lid on when the pillars the screws go in break, blank off unused ways, even try to get a tripping RCD to hold.
