New build with recycled parts on a ridiculous budget 120cm*60cm work area

2. Run a dedicated 32amp 5 wire 3 phase socket from the board (This is what I will do) and then tap 1 of the phases with a junction box to power the machine.

Is this then in a commercial environment if so.
You have to be careful with running a second 13A socket from the board and make sure it is on the same phase as the other.
I think there are rules to avoid have rings on different phases close together. Reason being is that although each socket would provide 230V there would be around 415V between the two lives from each socket.
