16TH EDITION IEE WIRING REGULATIONS EXPLAINED AND ILLUSTRATED SEVENTH EDITION PDF
As a result of many years developing and teaching courses devoted
to compliance with the IEE Wiring Regulations, it has become
apparent to me that many operatives and personnel in the electrical
contracting industry have forgotten the basic principles and concepts
upon which electric power supply and its use are based.
As a result of this, misconceived ideas and much confusion have arisen over the interpretation of the Regulations. It is the intention of this book to dispel such misconceptions and to educate and where necessary refresh the memory of the reader.
In this respect, emphasis has been placed on those areas where
most confusion arises, namely earthing and bonding, protection, and
circuit design. Much of Part 5 of the Regulations is not mentioned,
since it deals with selection of accessories etc. which needs little
or no explanation. Part 6 which deals with special installations or
locations, has now been included.
The current sixteenth edition of the IEE Wiring Regulations, also
known as BS 7671, to which this book conforms, was published
in June 2001. The philosophy and concepts that this book seeks to
explain remain unchanged, regardless of the edition. It is not a guide
to the Regulations or a replacement for them; nor does it seek to
interpret them Regulation by Regulation. It should, in fact, be read
in conjunction with them; to help the reader, each chapter cites the
relevant Regulation numbers for cross-reference.
It is hoped that the book will be found particularly useful by
college students, electricians and technicians, and also by managers
of smaller electrical contracting firms that do no normally employ
engineers or designers. It should also be a useful addition to the
library of those studying for theC&G 2381 qualification.
The IEE Wiring Regulations are divided into seven parts. These
follow a logical pattern from the basic requirements to the final
testing and inspection of an installation:
Part 1 indicates the range and type of installations covered by the
Regulations, what they are intended for, and the basic requirements
Part 2 is devoted to the definitions of the terms used throughout the
Part 3 details the general information needed before any design
work can usefully proceed.
Part 4 informs the designer of the different methods available for
protection against electric shock, overcurrent etc., and how to apply
Part 5 enables the correct type of equipment, cable, accessory etc.
to be selected in accordance with the requirements of Parts 1–4.
Part 6 deals with particular requirements for special installations
such as bathrooms, swimming pools, construction sites etc.
Part 7 provides details of the relevant tests to be performed on a
completed installation before it is energized.
