18th Edition 3rd Amendment 2024 – Wiring Regulations Update

Introduction:

The 3rd Amendment for the 18th Edition of IET Wiring Regulations, BS 7671 is about to bring a big change in this space. This public comment draft—available from May 8 through June 5, 2024—proposes amendments to address several important areas of electrical installation and safety. In this article, we explore what’s being proposed, what effect it could have, and how electricians can stay on the right side of the law.

Background:

BS 7671:2018 is the formal title for the 18th Edition of the Wiring Regulations and provides requirements for electrical installation and safety throughout the UK. The regulations undergo changes at periodic intervals to be in line with technological advances, safety enhancements, and feedback from industry.

The original version of the 18th edition was a blue book in 2018. The latest real change was with the introduction of Amendment 2 (AMD2) in 2022 moving to a brown book. Whilst the AMD2 brown book still applies, Amendment 3 will be a

The 3rd Amendment belongs to this continuing history, where new regulations and clarifications are put up to enrich and enhance electrical safety and practices of installations.

KEY CHANGES PROPOSED:

Connections of RCDs and Circuit-Breakers:

This amendment trails a BEAMA information bulletin that casts clarification on disparate connections of unidirectional and bidirectional RCDs and circuit-breakers. These changes are aimed to better the safety and reliability of electrical installations, especially those in residences where RCDs are commonly found.

Energy Efficiency:

New guidelines have stronger practical guidance regarding the energy-efficient design and installation practices. This will prompt the use of energy-efficient material and techniques that cut down on the overall use of energy in electrical installations.

Surge Protection:

Enhanced requirements for protection of electrical systems by Surge Protection Devices against transient over-voltages caused by lightning strikes and switching surges. SPDs are going to be made more essential for more types of installations, ensuring better safety for people and equipment.

Inspection and Testing:

The changes in the procedures for periodic inspection and testing to comply with the most up-to-date safety standards. Up-to-date methods of carrying out periodic electrical installations, which will ensure they remain compliant with BS 7671.

Installations of Electric Vehicle Charging Points:

Specific requirements for electric vehicle charging installations arise from the increased demand for safe and efficient EV charging infrastructure.

Impact on Electricians

The amendments being proposed in the 3rd Amendment are going to make electrical installations safer and efficient. For one to keep business as an electrician, he or she must welcome the changes so that they can also be up to the same level as they were before. Some of the critical steps that electricians must take include:

Training and Certification:

It is important that electricians get trained in new regulation regulations so that they get to understand the practical aspect of what they will be expected to do during implementation.

Update of Practices:

Put the new rules into day-to-day practices, with special attention to be made about RCD connections, energy efficiency, and surge protection.

Staying Informed:

Regularly check back for updates from the IET, amongst others related to get an idea of trends in updates and when these are going to be mandatory. You can reach the IET update page about this here: https://electrical.theiet.org/bs-7671/updates-to-18th-edition/

Conclusion – 18th Edition 3rd Amendment:

The prospective 3rd Amendment of the 18th Edition Wiring Regulations is a significant move in ensuring electrical safety and efficiency in the UK. Electricians can remain in compliance, by learning and making the above-noted changes, and therefore continue to provide safe and reliable installations for their customers. Watch for upcoming issues, and most importantly, be sure to participate in public consultation.
