Model forms for certification and reporting (informative). Contains model certificates and schedules for initial verification of electrical installation ‘EIC and Minor Works’. Plus model condition report and schedules for existing electrical installations ‘EICR’.

Regulation 514.12 (Notices: periodic inspection and testing) now contains an exception for domestic (household) premises in certain situations.Flag’ any questions you’re unsure of and re-visit at the end of the exam. Do not leave any questions unanswered. There are also a number of useful considerations to take into account on Periodic Testing & Inspection. Amendment 2 is an essential update to provide for the safety of electrical installations in the UK and it is now imperative that the industry is ready to work to this amendment before BS 7671:2018+A1:2020 is withdrawn.”

Understanding how to use the Wiring Regulations is recognised across the industry as an increasingly important skill. For that reason, there is a recognised qualification that tests your ability to use the 18th Edition book. Has much changed since the 17th Edition? Chapter 36: Continuity of service. 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.

Regulation 514.9.2 has been introduced to advise that all diagrams, charts, and information or instruction notices comply with the applicable standards specified. With so many changes afoot, it is easy to see the importance of maintaining and updating your knowledge of the Regs as an electrotechnical professional. 18th Edition Book in Practice

Chapter 53: Protection, isolation, switching control and monitoring is the largest chapter in Part 5 and concerns the devices used to turning things off. Whether it’s for overload, fault, fire or overvoltage protection, isolation or just control switching. Plus, the need to monitor parts of the installation when it’s impractical to turn circuits off for safety reasons. Regulation 443.5 (Risk assessment method) has been deleted and Annex A443 (examples of calculated risk level CRL for use of SPDs) has also been deleted. Section 514 - Identification and notices The 18th Edition book is predominantly used by, but not limited to, electricians and electrical contractors. If you are an electrician, you are probably already extremely familiar with the Regs. It not only supports domestic and commercial installations, but it also underpins electrical practices in environments like agricultural premises, caravans, external lighting, mobile units, temporary installations, fairgrounds, highway equipment and street lighting. Part 1 of the BS 7671 shows what sorts of installations are covered by the 18th Edition Regulations. It outlines what the regulations are meant for the basic requirements to follow for safety.

Corrigendum (May 2023) to BS 7671:2018+A2:2022

Chapter 42: Protection against thermal effects is the protection against the effects of heat, smoke and fire within an installation and preventing the loss of safety services. Escape routes and fire protection (informative). Cables in protected escape routes and fire sealing of cable penetrations within buildings. Determining prospective fault current (informative). Measured, calculated or enquiry. Line to line = (L to N) x √3 and between all line conductors = (L to N) x2.
