IEE Regs do not care about that, but it states something about the
insulation of the lower voltage cables has to be to mains spec.. Data
cables are not rated for mains voltages, so there has to be some sort of
physical barrier separating them. I would imagine that the data cable in
its own trunking would be OK.

That is a beter explantion of what I understand to be the case, than mine.
