Requirements for Electrical Installations, IET Wiring Regulations, Eighteenth Edition, BS 7671:2018+A2:2022 (Electrical Regulations)

Product Information

British standards which are referenced within BS7671 (normative). This is a long list of British standards mentioned in the book e.g., BS EN 60898.

Developing new, and amending existing regulations ahead of the next edition of the Wiring Regulations is a rigorous process. It not only involves standardisation with CENELEC and IEC regulations, but there is also a public consultation period or draft for public consideration (DPC). The DPC period is three months long, and means members of the UK public can offer comments for consideration ahead of a final draft and publication. Candidates must be aware that ‘Initial Verification’ is only practicable in the first instance of electrical installation. Any future testing of this circuit should be referred to under the periodic inspection banner. Initial Verification The technical content of this section has been extensively revised and expanded. Requirements of this section now apply to:Once you have decided what Part of the 18th Edition BS7671 your problem relates to go to the table of contents for that particular Part and find which Chapter it relates to.

On September 26 th, 1881 the world’s first fully electric-powered public street lighting was turned on in a town called Godalming in Surrey. These lights were provided by the German firm Siemens and used to replace the gas lighting system. However, all was not completely well with the new system. Indeed, as soon as power was switched on there were reports of problems with the wiring. This was particularly apparent on the side streets where the lights barely lit up the ground below them. More concerning, were reports of people coming to harm on exposed wires. By 1884 the town abandoned the project. Chapter 51: are Common rules that may apply to all electrical installations and concerns the operational conditions, conductor colours and labelling.
