Layout of BS7671 Wiring Regulations

The secret to knowing how to pass City & Guilds 2382-15 and to using BS7671 Wiring Regs is to know which regulations to apply and how to find them.

At 496 pages the Requirements for Electrical Installations, IET Wiring Regulations, BS 7671:2008+A3:2015 (Electrical Regulations), is a big book. Every page is densely packed with critical information and regulations. With so much information it is not possible to remember every regulation all the time. To find your way around the book a clear understanding of the organisation of the regulations is critical.


Wiring Regs - organisationThe Wiring Regs is organised into parts, chapters, sections and regulations.

Each part contains a chapter, each chapter contains sections, each section contains regulations. The Regulations themselves may contain multiple clauses.

Although there are 7 parts and 16 Appendices, the 17th Edition Wiring Regulations can best be understood by considering it as organised into four chunks of information:

  1. Part 1- Scope, object and fundamental principles
    This section outlines general requirements for installations
  2. Part 2 – Definitions
    This section details the 290 definitions which are used in the Regulations
  3. Part 3 to Part 7
    This is the body of the regulations, each part deals with a critical area of wiring regulations. Parts 3 to 6 describe general regulations in details and the longest part, Part 7 deals with special installations and locations.
  4. Appendices
    The extensive appendices provide detail information related to the Wiring Regulations
