Last chance to have your say on the 18th Edition!

21 August 2017

There are just two days left in which to have your say on proposed changes to the Wiring Regulations. 

Some of the proposed changes that Prysmian consider to be significant in the draft of BS7671:2018 Requirements for Electrical Installations are outlined below

  • Chapter 42 Protection against thermal effects. Calls for the installation of arc fault detection devices in electrical equipment to mitigate against fire
  • Chapter 44 Protection against voltage disturbances and electromagnetic disturbances. Has been redrafted to state that protection against transient over-voltages of atmospheric origin, such as lightning strikes, are in place where the consequences would affect human life, public services or commercial activity
  • Chapter 52 Selection and erection of wiring systems. This proposed regulation requires cables to be adequately supported against their premature collapse in the event of a fire throughout the installation and not just in escape routes as is currently the case.  
  • Section 753 Floor and ceiling heating systems. Extending the scope of the section on embedded electric heating systems to include both indoor and outdoor surface heating, such as those for de-icing or frost protection.
  • Part 8 Energy Efficiency One of the most significant of the proposed changes to this document is the addition of a new section, Part 8. This has been introduced to reduce the energy consumption of electrical installations; it covers several energy efficiency areas including limiting the voltage drop within an installation in order to reduce power losses in the wiring system which are evident as heat.

The Wiring Regulations apply to the design, erection and verification of electrical installations in commercial, residential, public and industrial premises along with infrastructure and even caravans. The proposals have the official status as draft for public comment and once all public comments are addressed, or incorporated, then a final version can be expected to come into effect on 1st Jan 2019, meaning all installations designed after 31st Dec 2018 must comply with the new standard.

The closing date for comments is Wednesday 23 August
