16TH EDITION IEE WIRING REGULATIONS EXPLAINED AND ILLUSTRATED SEVENTH EDITION PDF

It was once said, by whom I have no idea, that ‘rules and regulations
are for the guidance of wise men and the blind obedience of fools.’
This is certainly true in the case of the IEE Wiring (BS 7671)
Regulations. They are not statutory rules, but recommendations for
the safe selection and erection of wiring installations. Earlier editions
were treated as an ‘electrician’s Bible’: the Regulations now take
the form primarily of a design document.

It must be remembered that the Regulations are not a collection
of unrelated statements each to be interpreted in isolation; there
are many cross-references throughout which may render such an
interpretation valueless.

In using the Regulations I have found the index an invaluable
starting place when seeking information. However, one may have to
try different combinations of wording in order to locate a particular
item. For example, determining how often an RCD should be tested
via its test button could prove difficult since no reference is made
under ‘Residual current devices’ or ‘Testing’; however, ‘Periodic
testing’ leads to Regulation 514–12, and the information in question
is found in 514–12–02. In the index, this Regulation is referred to
under ‘Notices’.
