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 The information covered in this section is general and related to fundamental principles you will need to adopt prior to beginning design work. The first step to answering a real life problem or any exam question for that matter is to ask yourself. ‘What part of the book does this relate to?’ Remember the key facts attributed to each ‘part’ of the book. Think about the essential pieces of information you would need when physically undertaking an installation task. Appendix 4 includes minor changes concerning a cable surrounded by thermal insulation.

The IET’s (Institute of Engineering and Technology) Requirements for Electrical Installations goes by many aliases; the 18th Edition, BS7671:2018, the Big Blue Book, Wiring Regs, or simply the Regs. But regardless of what you call it, one thing is for sure – if you’re involved in the design, installation or maintenance of electric wiring, you’re going to need it.
