18th edition

If you weren't already aware, a revised version of the 18th Edition IET Wiring Regulations became mandatory on 1st January 2019. These changes including, new and revised regulations, additional chapters and reorganised sections, have been made to improve the safety of installers and to tighten the focus on energy efficiency

Note: Electricians should obtain their own copy of the BS7671:2018 regulations and follow the requirements outlined in the 18th edition of the IET Wiring Regulations - this blog is only a brief overview of the changes made.

  • An extra category (section 730 that caters for electrical shore connections and inland navigation vessels) has been added to cater for this specialised location.
  • Some new definitions have been added and certain existing definitions have been altered. For example, the word 'departure' has been added. This term can be used when an intentional decision is made not to comply with BS7671.
  • A new appendix (appendix 17) has been added that focuses on energy efficiency. This appendix makes recommendations so that designers can optimise the construction, assembly and installation of electrical components so they are energy efficient.
  • Arc fault detection devices have a more prominent place in chapter 42. They provide protection against electrical fires caused by faulty AC circuits.
