I think i would agree with that, DSkelton,
559.6.2.3 allows a 3-phase circuit to be split across three single phases sharing the same neutral as long as the three single phase circuits are isolated and protected by one 3-phase MCB/MCCB. Therefore treating the whole as a single three phase circuit.
However, it only specifically mentions lighting and not sockets. But then it doesn't condemn the use of other single phase outlets. So it might be a case of reducing ambiguity and applying common sense and waying up the probabilities of a possible loss of neutral where portable appliances are used.
I believe 'they' call it 'Risk Assessment'.....
