Err, yes :-(. I haev seen some lethal wiring in my time that was
installed by so-called 'professionals'.
Not lethal, but when I was studying at Bristol, we moved a 3-phase pillar
dril lfrom one lab to the next. Upon plugging it ino to the 3-phase
socket in said lab, it ran backwards. I probalby violated
$deity-knows-how-many rules by removign the cover of the motor switch box
and swapping over 2 of the wires.
However, quite why 2 sockets on opposite sides fo the same wall were
wired with a differnet phase sequence is beyond me.
