Ring final circuit test – updated guidance

Issue 89 (March 2022) of the IET’s Wiring Matters magazine contains an article by our Managing Director, Graham Kenyon, which examines the readings expected in Step 3 of the ring final circuit continuity test.

Read the article here

The article looks into why a mismatch between resistance per metre of the line and protective conductors leads to the reading not being the same at each test point on the ring for longer circuit lengths, for example when the circuit is wired in 4.0/1.5 mm2 twin-and-earth cable.

Updated guidance on the expected readings is provided in the 9th Edition of IET Guidance Note 3 Inspection & Testing, which Graham has updated.

The 9th Edition of Guidance Note 3 Inspection & Testing is due to be published on 28 March 2022, and is now available for pre-order from the IET Bookshop.

Graham Chairs discussion panel in National Conference on Competence and Building Safety

Our Managing Director, Graham Kenyon, was honoured to Chair a discussion panel at the recent IET National Conference for Electrotechnical & Building Safety Competence, on 31 January 2022.

The conference featured, keynote speaker, Dame Judith Hackitt, who discussed key points relating to accountability and competence including reference to her post-Grenfell report ‘Building a Safer Future’ (Jun 2019) which identified that the current system of building regulations and fire safety were not fit for purpose and that a culture change is needed to support the delivery of safe buildings.

Both parts of the National Conference are available to view on YouTube:

BS 7671:2018 18th Edition of the IET Wiring Regulations Interpreted by the experts

Hear about key changes being introduced in 18th Edition, from key committee experts.

BS 7671:2018 Requirements for Electrical Installations was issued on 2 July 2018. If you’ve been wondering what has changed and what you might need to do differently, attending this update seminar just four days later will give you the answers. A further date has now been added, 7 January 2019 at the IET, Savoy Place, London.

The three experts have active roles in the JPEL/64 committee led approach to the IET Wiring Regulations, so are well-placed to interpret the new edition and explain how it impacts the way you work.

Benefit from the discussion encouraged throughout the day, with plenty of time for delegates to question what, why and how with our panel as well as other delegates. You won’t get such comprehensive clarification by reading articles or sifting through the Regs themselves…
