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:

Island mode earthing arrangements: New Guidance in the Second Edition of the IET Code of Practice on Electrical Energy Storage Systems

Graham Kenyon, our Managing Director, has co-authored an article with Dr Andrew Crossland, Director of Advance Further Energy Ltd, for the latest Issue 84 of the IET’s Wiring Matters industry magazine.

Read the article here

The article looks at earthing arrangements for electrical installations that can operate in island mode (when the mains supply is lost) when they have a battery storage system connected. Importantly, it highlights changes in the earthing requirements introduced in the 2nd Edition of the IET’ Code of Practice for Electrical Energy Storage Systems, of which Graham is co-author along with fellow industry expert Martin Cotterell.

Free webinar – Responsibilities for those in an electrical installation design role

On 2nd February 2021, our Managing Director, Graham Kenyon, is joining John Peckham, of Astute Technical Services Limited, to provide an insight into the requirements of an electrical design role. The presentation will cover the fundamental principles of BS 7671, and review the duties on some other legislation and standards for electrical installation designers.

The event will be hosted by Colin Penfold, of the Operations department of Defra, and Colin, John and Graham will be answering live questions raised during the Webinar.

Working safely with energy storage and smart control technologies

Imaged linked from IET Wiring Matters web-site

Many electrical installations now incorporate new technologies, including embedded generation and home or building automation systems. As use of these technologies becomes more widespread, we need to be ever mindful that control of power to a circuit no longer relies on simple human switching operations. Electrical energy storage technologies that are capable of operating in island mode, continue to provide power when the grid is isolated.

Some incidents that have occurred recently when implementing energy storage systems outside the UK prompted Dr Andrew Crossland and myself to write an article for IET’s Wiring Matters. The article highlights the risks, and discusses safe isolation.

Further guidance on electrical energy storage systems can be found in the IET Code of Practice for Electrical Energy Storage Systems.
