It doesn't matter whether it excuses compliance with current Regulations.
The fact remains that the IET are never going to say that a situation which was deemed safe in previous editions is now unsafe. (The legal ramifications would be enormous.)
BS7671 requires us to make observation on non-compliances which may give rise to danger.
If the Regs. do not consider a non-compliance which complied at the time of construction to be unsafe, how can you then state the situation is potentially dangerous?
Well they have, there are many things which were once required by the regulations which are no longer compliant, fused neutrals being one example.
If the regs do not now consider an item which complied at the time to be unsafe now then it is not unsafe, however if the regulations do now consider it to be unsafe then it should be coded.
Fused neutrals complied with a previous edition.
Unfused supplies complied with a previous edition.
Bare conductors on cleats complied with a previous edition.
Green being used for L3 complied with a previous edition.
Open fronted switchgear complied with a previous edition.
Bare conductors encased in a wooden moulding complied with a previous edition.
The point is that if an item does not comply with current regulations and it is immediately dangerous then it is a C1
If an item does not comply with current regulations and is potentially dangerous it is a C2
If an item does not comply with current regulations and an improvement can be recommended for safety based on current regulations then it is a C3
