    Do the rules make any mention on wiring a small 3 phase installation. Is it required to be the brown, black, grey colours, or is the standard twin + earth allowed out to final circuits these days?

    If your sockets are 3 phase stick to the 3 phase colours. If they are single phase , brown blue and earth.

    Well for any 3 phase circuits its likely a 5 core cable with proper colours is used if circuits are not being wired with individual pvc single core cables. Im just curious is any mention of it made in rules now.

    I was thinking that alright, its really about being able to use PVC/PVC wiring etc. So that looks fine anyway.
