New 18th Edition March 2022<\/figcaption><\/figure><\/div>\n\n\n\n

Let\u2019s take a quick run through the new 18th<\/sup> Edition Wiring Regulations book, which includes Amendment 2 that was introduced in March 2022, BS7671:2018+A2:2022<\/strong>. <\/p>\n\n\n\n

We\u2019ll go into more detail and get you ready to pass your 18th<\/sup> Edition exam when we go through the book together fully in your 18th Edition online course at the-regs.co.uk<\/a>. <\/p>\n\n\n\n

There\u2019s eight Parts including the new Part 8, Functional Requirements<\/strong> and seventeen Appendices, however, Appendices 7 and 12 are empty, leaving just fifteen in this latest version of BS7671. <\/p>\n\n\n\n

\n ****\n<\/p>\n\n\n\n

Part 1: Scope, object and fundamental principles. <\/strong>This is made up of three chapters.\n<\/p>\n\n\n\n

Chapter 11: Scope<\/strong> is what the book does and doesn’t apply to. \n
Chapter 12: Object<\/strong> sets out the objectives and aims of the book. \n
Chapter 13: Fundamental Principles<\/strong>, sets out the criteria for the rest of the book and is a collection of basic rules that all electrical installations, whether commercial, industrial, or domestic should adhere to without going into detail as that is done within Parts 3 to 8 of the book.\n<\/p>\n\n\n\n

\n ****\n<\/p>\n\n\n\n

Part 2: Definitions<\/strong> is very useful and basically a dictionary of common terms and abbreviations used throughout the book. So, if you’re a bit rusty on some of the terminology within the 18th<\/sup> Edition, it’s worth spending a little extra time in Definitions. \n<\/p>\n\n\n\n

\n ****\n<\/p>\n\n\n\n

Part 3: Assessment of general characteristics.<\/strong> I like to think that Part 3 as all the things you would need to consider if you were designing an electrical installation from scratch. \n<\/p>\n\n\n\n

Chapter 31: Purposes, supplies and structure<\/strong>. What the installation is for, how it\u2019s supplied and how the installation is laid out.
Chapter 32: Classification of external influences<\/strong>. Although an empty chapter that just refers to Appendix 5, its aim is for the designer to consider any environmental conditions that may impact the installation.
Chapter 33: Compatibility<\/strong> This is where you would assess if any part of the installation will have a detrimental influence on any other parts of the installation.
Chapter 34: Maintenance<\/strong>. Here is where you would need to consider the frequency and quality of maintenance during the lifetime of the installation, including considerations for regular periodic reporting.
Chapter 35: Safety services.<\/strong> What safety services \u2018fire alarm, emergency lighting etc\u2019 are going to be within the installation and how are they going to be supplied.
Chapter 36: Continuity of service<\/strong>. Consider if there any parts of the installation where it may be more dangerous to lose the supply in the event of a fault i.e., life-support systems and if so, how we are going to overcome this. <\/p>\n\n\n\n

****<\/p>\n\n\n\n

Part 4: Protection for safety<\/strong> is where we start getting busy. Five chapters all about ensuring the safety of the users and occupants as well as the building itself. \n<\/p>\n\n\n\n

Chapter 41: Protection against electric shock<\/strong> contains methods used to reduce the risk to users of receiving an electric shock under normal and fault conditions. \n
Chapter 42: Protection against thermal effects <\/strong>is the protection against the effects of heat, smoke and fire within an installation and preventing the loss of safety services. \n
Chapter 43: Protection against overcurrent<\/strong>. Methods of protecting individual circuits from the effect of overload\/fault currents including which and when circuits won\u2019t need overcurrent\/fault current protection. \n
Chapter 44: Protection against voltage disturbances and electromagnetic disturbances <\/strong>covers the safety of installations from voltage and electro-magnetic disturbances which includes voltage surges due to, earth faults, atmospheric origin, switching and electromagnetic disturbances and undervoltage or loss of voltage. \n
Chapter 46: Isolation and switching<\/strong> is all about turning things off whether it\u2019s isolation for maintenance or to functionally control a circuit or in an emergency.\n<\/p>\n\n\n\n

\n ****\n<\/p>\n\n\n\n

Part 5: Selection and erection of equipment<\/strong> or choosing and using as I like to say and it’s all about the equipment and materials used to comply with Part 4. \n<\/p>\n\n\n\n

Chapter 51: are Common rules<\/strong> that may apply to all electrical installations and concerns the operational conditions, conductor colours and labelling. \n
Chapter 52: Selection and erection of wiring systems.<\/strong> It\u2019s about cables, conductors, installation, connection, and protection from external influences, such as water, heat, impact etc. \n
Chapter 53: Protection, isolation, switching control and monitoring<\/strong> is the largest chapter in Part 5 and concerns the devices used to turning things off. Whether it\u2019s for overload, fault, fire or overvoltage protection, isolation or just control switching. Plus, the need to monitor parts of the installation when it\u2019s impractical to turn circuits off for safety reasons.\n
Chapter 54: Earthing arrangements and protective conductors.<\/strong> The most important conductors in any electrical installation are the various types of earth conductors, main-earth, protective conductors, and bonding conductors. Here you can discover what size and where when to use each.\n
Chapter 55: (all) Other equipment.<\/strong> All the rest of the electrical equipment not covered in other Parts of BS7671 except Part 7. Generator, motors, transformers, auxiliary \u2018control circuits\u2019 and lighting.\n
Chapter 56: Safety services<\/strong> concerns the selection and installation of supplies for safety services within an electrical installation. Remember it\u2019s supplies to, and not the individual safety service e.g. the fire alarm installation itself.\n<\/p>\n\n\n\n

\n ****\n<\/p>\n\n\n\n

Part 6, Inspection and testing.<\/strong> Remember, this Part doesn’t go into details on how to physically complete inspection and testing, it\u2019s all about the requirements.\n<\/p>\n\n\n\n

Chapter 64, Initial verification<\/strong>. It’s what you need to do to verify compliance with BS7671 of new electrical installations
Chapter 65, Periodic inspection and testing<\/strong> is reporting on the condition of existing installations.
(Includes in each chapter what certification, reports and documentation will need to be completed in each case.)<\/em> <\/p>\n\n\n\n

Part 7: Special installations or locations<\/strong>. Twenty sections covering twenty installations, environments, or locations where there’s an increased risk of electric shock. Usually due the presence of ordinary, unskilled, and unsupervised people and wet conditions or where things may get knocked about, or a combination of all.\n<\/p>\n\n\n\n

\n So, for safety there are additional regulations concerning these areas which you need to be aware of.\n<\/p>\n\n\n\n
