Hi there fellow sparks,

I'm hoping some kind soul would refresh an old memory of any precautions I should bear in mind when rewiring a large open plan office (Primarily IT equipment);

All the wiring will be contained within skirting trunking, and there are around 180 DSSO's to be had, probably wired something like 10 doubles per MCB.

I'm proposing that this should be spread about the three phases, to balance loads etc, thus having 60 doubles per phase.

Now, the sockets are very evenly distributed around the skirting, and each socket will be within human reach of the next.

Are there any regulations, or special precautions I should be taking, knowing that in this situation, it would be possible for a monitor to be on red phase, and base unit on blue phase.

I always over-worry when working on three-phase - it's what you get for spending a long time on domestic work :-)

Any tips & pointers are welcome.

Have a nice day, y'all [Linked Image]
