Get ready for the 18th Edition

The long-awaited changes to the 18th Edition of the IET Wiring Regulations are set to be published within weeks. Hager technical and training manager Paul Collins outlines the background to the proposed changes and the key areas professional electricians need to be aware of

What are the IET Wiring Regulations?

While the outlined changes are important, it’s also essential for electrical contractors to understand the rationale behind the changes in order to ensure they remain compliant. Re-ferred to as ‘The Regs’ throughout the industry, the IET Wiring Regulations are the national standard for the design and erection of electrical installations in domestic, commercial and other buildings and installations.

Why are they changing?

The 18th Edition changes have been undertaken for four primary reasons:

1. To ensure harmonisation with current European CENELEC standards
2. To further clarify existing IEC regulations
3. To further improve safety standards
4. To allow for new technology and methods to be used in future years

They are in response to the ways in which technology continues to develop and evolve. However, while a large part are as a result of technological advancements, another key driver is to fall in line with European standards, largely based on an IEC and on European CENELEC harmonised documents (HDs). As a full member of the European Standard CENELEC, the UK has to adopt the technical intent of the 60364 standard published by the International Electrotechnical Commission (IEC) to ensure harmonisation. Importantly, Brex-it will have no effect on the planned changes.

What are the proposed changes?

At Hager, we believe some of the most significant changes include:

  • Recommendations for Arc Fault Detection Devices (AFDDs) in AC final circuits
  • Changes to the requirements for the inclusion of surge protection devices
  • Supporting wiring systems within buildings against their premature collapse in the event of a fire
  • Provision of overload protection of devices within assemblies
  • Consideration for the use of different types of RCDs.
  • With a number of key areas in the spotlight, Hager is committed to helping ensure electri-cal contractors have a full working understanding of what will be different once the new regulations come into full force on 1 January 2019.

    As part of our commitment, we’ve recently launched ‘Regs Live’, an initiative developed to make sure electricians are fully aware of what they will need to do differently going for-ward.

    As part of Regs Live, a Hager team will be attending a number of key trade events through-out the year where Hager experts will be on hand to answer questions from electrical pro-fessionals and offer guidance concerning the revised regulations.
