Course Overview

This course will cover: the design of electrical installations for, and specification of, electric vehicle charging equipment installations; the requirements detailed in Section 722 of BS 7671:2018; and recommendations of the IET Code of Practice for Electric Vehicle Charging Installations, 3rd Edition. It provides an understanding of the key requirements for protection against electric shock, including selection and use of earthing systems, and introduces vehicle-as-storage, wireless power transfer (WPT) and smart infrastructure installations.

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.

7 January 2018 Principal Speaking at Seminar 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 should be used for new designs from 1 January 2019. 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.

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.

RCD protection for socket-outlets in the 18th Edition (BS 7671:2018)

(c) IET anbd BSI

Image from IET web-site

The publication of the 18th Edition of the IET WIring Regulations (forthcoming BS 7671:2018) is imminent, and BSI and the IET have publicised some of the key changes, which can be viewed on the IET web-site.

When Amendment No. 3 to BS 7671:2008 was published in 2015, we reported on changes to RCD protection for socket-outlets in Regulation 411.3.3, with socket-outlets in AC systems rated up to and including 20 A requiring RCD protection unless a risk assessment stated otherwise.

With the 18th Edition, Regulation 411.3.3 requires all socket-outlets in AC systems rated up to and including 32 A to be protected by a 30 mA RCD, the only exception being for installations other than in dwellings, where a documented risk assessment determines RCD protection is not necessary.

The salient facts here for Regulation 411.3.3 that designers will be obliged to consider are:

  1. The upper rating for socket-outlets requiring RCD protection in accordance with Regulation 411.3.3 has increased from 20 A to 32 A.
  2. There is no longer an exception to Regulation 411.3.3 for dwellings, regardless of whether a risk assessment was in place, and regardless of the appliance(s) to be served. An AC appliance that is not compatible with 30 mA RCDs in dwellings must therefore be permanently connected to the electrical installation, unless it is rated for use with a socket-outlet exceeding 32 A.
  3. If an exception is made in installations other than dwellings, to omit RCD protection for socket-outlets rated at 32 A or less, there must be a documented risk assessment that determines RCD protection is not necessary.
