It's not. It just shows how thick the great unwashed really are.

There is a junction box in the loft here, it's *something* to do with the
lighting (ie depower the lighting and it is depowered...). It's a four
way box with at least 5 if not 6 cables into it a couple of which are 3
core and earth. When I was putting down the loft flooring several of
these cables took interesting routes over the top of joists or just
generally curious paths. I simply numbered each cable, and noted to which
terminal the wires in each cable went to. Took the wiring apart, fixed
the floor, put it back together according to my notes. Everything works
as it did, no fusen popen. I still haven't any idea what thoase cables do
other than in the vaugest guessing terms.

So why doesn't the great unwashed when presented by the wires/cables in a
loop thru/switch drop ceiling rose mark 'em and note down which one goes
where it's not difficult, unless you are thick.

Not to mention taking a photo first. For me that's now standard
procedure before disconnecting or disassembling anything non-trivial.
