Guidance Note 3: Inspection & Testing is a fundamental guidance book for all those involved with the testing and inspection of electrical installations. It also contains essential guidance for those studying for inspection and testing qualifications and has been fully updated to BS 7671:2018. The 18th Edition of the IET Wiring Regulations published in July 2018 and came into effect in January 2019. Changes from the previous edition include requirements concerning Surge Protection Devices, Arc Fault Detection Devices and the installation of electric vehicle charging equipment as well as many other areas.

Guidance Note 8: Earthing & Bonding includes information from BS 7430 Code of Practice for Earthing. It covers key guidance for all involved with specifying, designing, installing or verifying electrical installations and has been fully updated to BS 7671:2018+A2:2022. BS 7671:2018+A2:2022 incorporates changes from the first amendment, published in 2020, regarding Electric Vehicle Charging Installations to provide greater guidance on embracing changing technology within this sector. Additional changes within the second amendment include protection against thermal effects and fire caused by electrical equipment, protection against voltage disturbances and electromagnetic disturbances, and a new chapter on prosumer's low-voltage electrical installations covering energy efficiency measures, the interface with the smart grid, the management of electricity consumption, the management of renewable sources of electricity, and energy storage.

Guidance Note 8: Earthing & Bonding

The complexity of integrating the earthing of a 25kV electrified railway with various electrical distribution systems and exposed conductive parts, means that it is impossible to prescribe one earthing and bonding design solution that addresses the needs of every railway. Therefore, this creates different earthing designs for individual railways. The guide implements a common earth system formed by bonding lineside assets and structures to the traction return system, effectively forming a low impedance meshed earth network. The guide covers: Description of the AC traction electrification distribution system Mass of earth as part of the traction return system Traction return requirements and circuit configuration Protective provisions for humans Electrification system assets excluding the traction return Assets not forming part of the traction return System measurements Functional requirement of lightning protection for civil railway structures Principles of earthing at AC DC Interface Safe working during maintenance, renewal and decommissioning Electrical safety is required to minimise the potential difference between all exposed conductive parts and systems sharing the system earth. This new guide explains the principles of a 'common earth' system (traction and non-traction) which is able to provide a robust and low impedance path to earth. This guide aims to assist infrastructure owners, railway designers and installation contractors in adopting a harmonised approach towards earthing and bonding design philosophy for 25kV railway infrastructure.

This is the 4th edition of the IET's Code of Practice for Inservice Inspection and Testing of Electrical Equipment. The book has been revised to take account of the PAT aspects of Professor Löfstedt's report and the HSE view that promotes a proportionate riskbased approach when assessing the safety of electrical equipment and appliances. This will help users, those responsible for the equipment and testers of the equipment to maintain safety. HSE encourages the adoption of this approach and the changes will also be reflected in the City & Guilds 2377 course. The Code of Practice enables duty holders to understand the requirements placed on them in law to maintain electrical equipment, using correct documentation, that falls under their control and to understand what inspection and testing involves. It also gives guidance to those carrying out inservice inspection and testing of electrical equipment (PAT).

The Code of Practice for Electric Vehicle Charging Equipment Installation, 3rd Edition has been updated to align with the current requirements of BS 7671. This includes updated guidance on the electrical installation requirements of BS 7671:2018 (Section 722 Electric vehicle charging installations) to be published in July 2018. The Code of Practice provides an overview of electric vehicle charging equipment, considerations needed prior to installation, physical installation requirements, relevant electrical installation requirements of BS 7671:2018 and specific requirements when installing electric vehicle charging equipment in location's such as dwellings, on-street locations, commercial and industrial premises. Also included are useful installation checklists and risk assessment templates. Therefore this publication provided useful guidance for anyone interested in the installation of electric vehicle charging points. This is a practical guide for use by anyone planning to install electric vehicle charging equipment. It provides specific electrical installation requirements for electrical contractors as well as essential guidance for anyone planning to specify, procure or manage the installation of such equipment.

The IET Wiring Regulations are of interest to all those concerned with the design, installation and maintenance of electric wiring in buildings. The market includes electricians, electrical contractors, consultants, local authorities, surveyors and architects. This book will also be of interest to professional engineers, as well as students at university and further education colleges. All users of the IET Wiring Regulations need to be aware of the coming changes in the 18th Edition (BS 7671:2018). This is intended to come into effect on 1st January 2019, although industry needs to start preparing for this from its point of publication (2nd July 2018).
