Regulation 717.411.4 has been expanded to take account of PME. Section 722 - Electric vehicle charging installations Chapter 6.1 - new guidance on the provision of horizontal movement joints on masonry clad buildings and increasing cavity wall performance standards COLREGS set out the conduct of vessels in any condition of visibility, specifically when in sight of each other, and also in or near areas with restricted visibility.They make it clear when you are the stand on vessel, the give way vessel and the correct action to take when in close quarters with other vessels to avoid a collision. They also help you to anticipate the actions of another vessel. This is a new appendix that provides guidance for the types of safety signs, warning signs and instructions required to be applied to electrical installations. Appendix 13 Escape routes and fire protection Additional, supplementary information relating to other parts of the book – eg Appendix 6 has copies of the certificates and reports used with Inspection and Testing – Part 6 and Appendix 3 has the maximum disconnection times for RCDs and current/time graphs for protective devices which ties into Part 4 etc.

Regulation 514.12 (Notices: periodic inspection and testing) now contains an exception for domestic (household) premises in certain situations. Additional requirements have been added for installations where the generating set or sets may operate in parallel with other sources including systems for the distribution of electricity to the public.Part 6: What inspections and tests should be done to show it’s safe and the certificates to be used. The wiring regulations have been regularly updated ever since to reflect both new developments in wiring and updated modes of best practice. They remained the responsibility of the Society who later became known as the Institute of Electrical Engineers. They now tend to be referred to by their acronym, the IET. Over the years, regulatory standards across nations and continents have become increasingly aligned. This began in 1981 when the regulations aligned with those of the International Electrotechnical Commission (IEC). In 1992, the British Standards Institute ( BSI) formalised the wiring standards under BS 7671. More recently, the European Committee for Electrotechnical Standardization has harmonised wiring regulations further. The following paragraphs review how a specific ‘part’ of the book may materialise in an examination question format. We’ll be using section 6 for this, which alludes to the inspection and testing of electrical installations. The examination consists of sixty questions, and must be completed within two hours. This gives an average of two minutes per question. Candidates are allowed to enter the examination hall with a copy of the 18th edition bs7671 book. You should use the book in accordance to the questions asked. Time Considerations

For all other cases, protection against transient overvoltages shall be provided unless the owner of the installation declares it is not required due to any loss or damage being tolerable and they accept the risk of damage to equipment and any consequential loss. Regulation Group 643.3 has been redrafted. The requirements for testing insulation resistance where equipment is likely to influence the verification test or be damaged has been clarified and reference is made to a 250 V DC test following the connection of equipment. Regulation 514.9.2 has been introduced to advise that all diagrams, charts, and information or instruction notices comply with the applicable standards specified. Lastly, it is an unfortunate truth that some electricians wrongly advise clients that installations have failed testing, basing their assertions on regulations set out in outdated edition guides. Whether this is to secure additional work or due to the tradesman’s ignorance is irrelevant; all electricians should arm themselves with the current legislation. This may not be key information for your exam, but honesty and transparency should be leveraged in whatever activity you undertake as an electrician- trainee or otherwise. In summary I’ve also been qualified tutor since 2008 and have taught electrical installation ‘C&G, EAL and Logic’ courses and we’ve been successfully teaching the Wiring Regulations online here at the-regs.co.uk since 2014 and have had hundreds of students pass 18th Edition exam – why not join them today? Recent PostsRegulation 443.4 for determining if protection against transient overvoltages is needed has been redrafted. Regulation 443.4.1 now requires protection against transient overvoltages to be provided where the consequence caused by the overvoltage could result in: The 18th Edition exam is an assessment of your ability to use the Wiring Regulations BS7671 2018 out there in the big world. As such problems and questions may not always be worded exactly as you come across them in the book. Whilst the IET allows the book to be taken into the exam with above assistive learning tools, the IET wiring regulations books are not allowed to contain any of the following: Regulation 443.4.2 requires protection against overvoltages to be considered in the case of equipment likely to produce switching overvoltages or disturbances and gives conditions. The BS7671:2018 examination is the same regardless of whether you’re entirely new to the field, or if you’ve completed examinations on historic wiring regulation editions. But if you’re fully up to speed on the last Regs book, you may feel confident enough to focus your revision on the changes that have occurred this time around.

Regulation 531.3.3 now states that RCD Type AC shall only be used to serve fixed equipment, where it is known A new Regulation 514.16.1 has been introduced requiring a label to indicate the presence of SPDs. However, there is an exception for domestic (household) premises or similar. Chapter 53 - Protection, isolation, switching, control and monitoring Regulation 531.3.2 indent (ii) highlights the use of RCBOs for individual final circuits in residential premises to Some of these are general good behaviour rules while others are very specific, prescribed obligations.Modifications have been made to Regulation Group 543.7 concerning earthing requirements for the installation of equipment having high protective conductor currents. Understand the requirements for selection and erection of equipment for electrical installations (14 questions, 23%)

An increased focus on energy efficiency, including recommendations around the design and erection of electrical installations. The table below outlines what is covered in the BS 7671 book outlining the IET Requirements for Electrical Installations. It also highlights the number of questions in the exam will target the different sections covered in the book. The ‘Test Value (%)’ column serves to show how much of your time should be spent revising each book section. This is based on the total number of questions covered by each book section out of the 60 that will be asked. Book Part Finally don’t forget, if you do find yourself of need of legal advice relating to the COLREGS, the RYA Legal team can assist all RYA members with free guidance on the interpretation and scope and application of the rules. Regulation 411.3.3 has been redrafted and now has three indents. There is still an exception to omit RCD protection where, other than BA1, BA3 or children (BA2, BA3) and mobile equipment (not exceeding 32 A) for use outdoors, a suitably documented risk assessment determines that RCD protection is not necessary. Determine which ‘part’, sub-section and regulations within the 18th edition book the question alludes to. This is extremely important!The above examples could be produced in alignment with any ‘part’ of the 18th edition book. However, this set of inspection and testing guidelines serve to offer an insight into format, content style, and tone of questioning across the full examination. This understanding should be carried into revision endeavours on all topics included within the 18th edition book.
