New wiring regulations now in full effect

ECA’s #Project18 is helping industry get up to speed with important changes to the Wiring Regulations (BS7671).

The 18th Edition of the Wiring Regulations, also known as BS 7671, came into full effect on 1 January 2019. The changes were first introduced in July 2018.

The new publication is essential for all electrotechnical designers and installers. Changes vary from simple rewordings to some complete Regulation overhauls.

BS 7671 is not retrospective – installations designed after 31 December 2018 are to comply with BS 7671:2018.

ECA recommends installations are kept up-to-date by carrying out regular maintenance inspections alongside periodic testing of electrical systems, to highlight any potential failings and areas of improvement.

ECA Senior Technical Engineer Gary Parker commented:“The way we design, install and use installations is rapidly evolving with new technologies, shifts in end-user behaviour, and lessons learned from previous editions of the book. The 18th Edition ensures that UK technicians stay ahead of the curve and continue to design, install and maintain electrical installations to a world-class standard.”

Key changes in the 18th Edition include:

  • The requirements on SPD (surge protection device) consideration and usage have been revised
  • There are new requirements for AFDDs (arc fault detection devices) have been considered
  • Requirements for cabling support and fixings have changed
  • More emphasis has been placed on protective devices being selected properly and working together in a system
  • There have been some changes applying to work within special locations
  • There is a new appendix on energy efficiency
