Hi guys, iv been doing loads of basic new build single phase.
The next one is going to be 3 phase and a bigger house. I will treat as normal apart from adding a 3 phase board and balancing on the phases.
The owner has asked me to set up a temp supply. Can I do this but setting up say a garage board and couple of sockets, but using just one phase and not connecting the other two in, obviously neutral and earth will be connected. Thank you for any help
If the 3 phase meter is installed then you could do worse than fit one of these 4 pole isos beside it,

and then take L1 and N on some meter tail to any old single phase box with an RCD incomer feeding a board full of sockets. The switch stays and makes it easier to hook up and test the final 3ph board later.
I have used a wooden trestle in the past (yes this sort of thing, really that crude ) with plywood board on it with a DIN box RCD and a couple of breakers on one side, and about 8 double sockets on the other
If the decorators are in as well, it can be waterproofed with a bin bag or two, This is for when all the walls are being plastered, and there was no wish to leave a funny patch where the temp board was. I have even been known to screw it to the floorboards for the duration,,,
The RCD means it is not so serious if the earthing is a bit hit and miss.
