The bit about never re-using cable of the correct spec is rather vague. It
may have been straight off the drum and clipped to a beam etc with hardly
being bent - or flexed many times while routing through walls and under
floors, etc. So common sense would apply. Although I doubt in practice
it's much of an issue unless extending an existing installation where it
might be thought all the cabling must be replaced?
