Re: Re: House wiring - follow up

" Where cable runs are concealed behind plaster they must be installed
in
'acceptable zones' which are intended to reduce the danger to the cables
and
to people who drill holes or knock nails into walls.  Cable runs must only
follow paths which are horizontal or vertical from an outlet, or be within
150mm of the top (but not the bottom) of the wall, or within 150mm of the
angle formed by two adjoining walls.  Where a cable run has a diagonal, it
must be protected by being enclosed in steel conduit, or must be a cable
with an earthed metal sheath (such as mineral insulated cable), or an
insulated concentric cable.  In this latter case, the phase conductor will
be surrounded by the neutral so that if a nail or screw penetrates the
cable
it will be impossible for it to become live.  The internal partition walls
of some modern buildings are very thin, and where cables complying with the
requirements are within 50mm of the surface on the other side they will
require protection."

that

our resident 16th regs man (Mr Hoyle?)  may be able to find his OSG before
