Can you tap off a 3 phase supply to meter block to suppy a 230 board.

Yes of coarse you can.

 

[irishsailor]

thank you for your swift reply what is the best way to do it

Just do as you would for a 230v head.

Exactly pick a phase and then tap into it exactly as you would do as if it was just single phase and you were adding another board in. Make sure you have a 4 pole isolator at the origin so as you can isolate both the 3 phase and single phase board from 1 point.

and ( hope not teaching to suck eggs) pick the phase with least load, to balance

Last time I tried tapping off a three phase supply I ended up spending the week on the couch.

Probably should have consulted her before asking her best mate......
