What danger do you envisage might occur?

One thing to check is whether the equipment manufacturer has a specific overcurrent protective device rating (some German machines, for example, specify 25 A, which can be tricky in the UK.

And of course, if using a socket-outlet rated up to 32 A, is the outlet RCD protected in line with Regulation 411.3.3?

Thank you for the note about specific over current protective device rating.

I was wondering if there would be a danger associated with the loads being unbalanced for the 3 phase breaker supplying the socket.
