Phases in dado trunking.

[Swa33er]

Hi all and thanks in advance for any replies.
I was wondering if whether when having more than one phase inside a dado trunking are you required to mark up the trunking with a 400v marker/label like you would at a multi gang light switch??

No requirement.
According to bs 7671 a warning label is only required when the line to earth voltage exceeds 230 volts ac. You would only have 400volts between phases.
I still however label a 3phase db with a 400v sticker/warning notice just the way I was taught and I think it's good practice

No there is no requirement.

Agree with Lee. Same goes for light switches.

I don't know if it's a requirement (ignore that cheers lee) but I certainly would, not a big sticker but maybe the smaller etched ones placed on the lid, just in case someone who isn't competent decides to have go at chucking a couple of extra sockets in.
