Amendment to IET Wiring Regulations is now published

The Institution of Engineering and Technology (IET) has called on  electrical professionals to get up to speed with the latest amendments to the IET Wiring Regulations.

IET Wiring Regulations BS 7671:2008 incorporating Amendment 3:2015 were launched on January 5th and are now available in both print and digital formats.

The amended regulations set out the national standard for which all new and amended electrical installations need to comply. The IET is urging all electrical professionals to ensure they are familiar with the new requirements as all installations designed after June 30th, 2015, are to comply with BS 7671:2008 incorporating Amendment 3:2015.

This latest amendment, the third following Amendment 1 which was published back in 2011 and Amendment 2 in 2013, has been published as a new consolidated book. The amended regulations include changes to the electrical condition report section, new requirements for mobile and transportable electrical units and changes for the installation of luminaires and light fittings – bringing them in line with the latest international and European standards.

A new requirement is new Regulation 421.1.201 which requires that within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and shall have their enclosure manufactured from non-combustible material, or enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12. This has been developed to safeguard against the risk of fire caused by overheating of connections in consumer units. Regulation 421.1.201 does not come into effect until January 1st, 2016, but this does not preclude compliance with this regulation prior to this date.

Geoff Cronshaw, Chief Electrical Engineer at the IET said: “The launch of the IET Wiring Regulations BS 7671:2008 incorporating Amendment 3:2015 marks the launch of an update to the way all electrical professionals are required to carry out their work in order to safeguard themselves and the public. With this in mind, it is essential that all electrical professionals ensure that they are up to speed with the new requirements.

The amended IET Wiring Regulations are available in print and online from the IET’s new digital platform, Electrical Standards Plus.
