Yup that is true, so the sparks could argue it is legit... not sure if
the socket counts as a "visible" accessory though...

In other words (getting back to the point of the rule) if you were going
to drill into the wall you might avoid directly above the double socket,
but would you also avoid horizontally aligned with the other socket if
it is hidden behind the extractor duct?



Oh sure. I didn't say that this was a good idea, but I don't think
that it explicitly breaks the regulation.


526-06-06 (applies to hidden, unprotected cables at 50mm depth)

".. be installed within 150mm of the top of the wall or partition or
within 150mm of an angle formed by two adjoining walls or partitions.
Where the cable is connected to a point, accessory or switchgear on
the wall or partition, the cable may be installed outside these zones
only in a straight run either horizontally or vertically, to the
point, accessory or switchgear."

The On-Site Guide shows an illustration of this and has a cable at an
angle (not allowed in this context) to show the point. However, it
doesn't have this example.

I suppose that it's better to do it as has been done in this case than
to go at an angle. A completely correct way from this perspective
would have been to run the cable up from each socket to the 150mm band
near the ceiling and back down again.

Personally, I always trace the cables anyway.
