BS 7671:2018+A2:2022, expected to publish in spring 2022, will be the first full, consolidated Amendment to the 18th Edition IET Wiring Regulations, which was published in 2018. It will also include Amendment 1:2020, which was published as a standalone PDF in February.What are the proposed changes?One of the largest proposed changes in Amendment 2 is a new Part 8 – Functional Requirements. This includes Chapter 82: Prosumer’s Low-Voltage Electrical Installations. A prosumer is both a producer and consumer of electricity. This new chapter sets out the requirements for Prosumer Electrical Installations (PEIs), including considerations for interaction with the smart grid, safety requirements (including earthing arrangements), proper functioning and implementation. Electrical installers will have a large part to play in the selection of the most appropriate equipment and a comprehensive knowledge of this area will be key as prosumer technologies develop.Important changes to fire safety requirements are proposed in Chapter 4, covering the design of electrical installations in industrial, commercial and multiple-occupancy homes, as well as new information for ‘protected escape routes’.
