Is it safe to supply a single phase machine from a 3 phase 5 pin commando socket?

Mike Hancock

The socket rating is ok (32A, FLA of machine is 24A), but current would only be drawn on one phase

    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.
